    Full Text Available We report a case of aniridia associated with congenital aphakia and secondary glaucoma. A 35-year-old male presented with aniridia, congenital aphakia and secondary glaucoma in both eyes. After an unsuccessful medical management, he underwent trabeculectomy with mitomycin C and anterior vitrectomy under local anesthesia in his left eye. Postoperatively, at the end of six months, intraocular pressure (IOP in his left eye was controlled without medications. This case highlights the rare association of aniridia with congenital aphakia and secondary glaucoma.

  2. Three cases of post-cataract surgery endophthalmitis due to Rhizobium (Agrobacterium) radiobacter. (United States)

    Moreau-Gaudry, Viviane; Chiquet, Christophe; Boisset, Sandrine; Croize, Jacques; Benito, Yvonne; Cornut, Pierre Loïc; Bron, Alain; Vandenesch, François; Maurin, Max


    We present three unrelated post-cataract surgery endophthalmitis cases caused by Rhizobium radiobacter, hospitalized in three different hospitals. Early diagnosis was obtained in two cases by bacterial DNA detection in vitreous samples. All patients recovered from infection, but pars plana vitrectomy was needed in two patients due to rapid clinical deterioration. PMID:22259203

    Mahmood Joshaghani


    Conclusions: Although piggyback IOL implantation for infantile cataract is optically acceptable as a treatment option, there is no significant difference in visual outcomes compared to aphakia. The incidence in reoperation due to complications in patients aged 6 months or younger is higher than those treated with aphakia.

    Felius, Joost; Busettini, Claudio; Lynn, Michael J.; Hartmann, E. Eugenie; Lambert, Scott R.


    After early surgery for unilateral infantile cataract, both treatment groups in the Infant Aphakia Treatment Study (IOL or contact lens correction of aphakia) showed no difference in the occurrence of fixation instabilities at age 4.5 years. The overall incidence of nystagmus was relatively low.

  5. Implantation of iris-claw Artisan intraocular lens for aphakia in Fuchs′ heterochromic iridocyclitis

    Directory of Open Access Journals (Sweden)

    Ahmad Kheirkhah


    Full Text Available Implantation of iris-claw Artisan intraocular lens (IOL is a surgical option for correction of aphakia; however, these IOLs have not been used in eyes with uveitis including Fuchs′ heterochromic iridocyclitis (FHI due to possible risk of severe postoperative intraocular inflammation. In the case reported here, we secondarily implanted an Artisan IOL in a 28-year-old man with FHI who had aphakia with no capsular support due to a previous complicated cataract surgery. Enclavation was easily performed and no intraoperative complication was noted. Postoperative course was uneventful with no significant anterior chamber inflammation during 12 months of follow-up. Although there were few deposits on the IOL surface, the patient achieved a best-corrected visual acuity of 20/20 without developing glaucoma or other complications. Therefore, Artisan IOL may be considered for correction of aphakia in patients with FHI. However, studies on large number of patients are required to evaluate safety of the procedure.

  6. The validity of labeled parameters of aphakia-correcting soft contact lenses. (United States)

    Molinari, J F; Semes, L


    This study examines the validity of labeled parameters of aphakia-correcting soft contact lenses. The Nikon Projection Lensometer (NPL) and the Hydro-Vue Soft Lens Analyzer (HSLA) were used by two independent inspectors to measure 51 aphakia-correcting lenses. The contact lens power, diameter, and base curve were measured by each of the inspectors and compared to the labeled parameters. All parameter relations that were analyzed revealed that measurements made by the inspectors were not statistically different (p greater than 0.05) from each other and that their combined measurements were not statistically different (p greater than 0.05) from the labeled values.

    Kenta Wada

    Full Text Available Microphthalmia is a severe ocular disorder, and this condition is typically caused by mutations in transcription factors that are involved in eye development. Mice carrying mutations in these transcription factors would be useful tools for defining the mechanisms underlying developmental eye disorders. We discovered a new spontaneous recessive microphthalmos mouse mutant in the Japanese wild-derived inbred strain KOR1/Stm. The homozygous mutant mice were histologically characterized as microphthalmic by the absence of crystallin in the lens, a condition referred to as aphakia. By positional cloning, we identified the nonsense mutation c.444C>A outside the genomic region that encodes the homeodomain of the paired-like homeodomain transcription factor 3 gene (Pitx3 as the mutation responsible for the microphthalmia and aphakia. We examined Pitx3 mRNA expression of mutant mice during embryonic stages using RT-PCR and found that the expression levels are higher than in wild-type mice. Pitx3 over-expression in the lens during developmental stages was also confirmed at the protein level in the microphthalmos mutants via immunohistochemical analyses. Although lens fiber differentiation was not observed in the mutants, strong PITX3 protein signals were observed in the lens vesicles of the mutant lens. Thus, we speculated that abnormal PITX3, which lacks the C-terminus (including the OAR domain as a result of the nonsense mutation, is expressed in mutant lenses. We showed that the expression of the downstream genes Foxe3, Prox1, and Mip was altered because of the Pitx3 mutation, with large reductions in the lens vesicles in the mutants. Similar profiles were observed by immunohistochemical analysis of these proteins. The expression profiles of crystallins were also altered in the mutants. Therefore, we speculated that the microphthalmos/aphakia in this mutant is caused by the expression of truncated PITX3, resulting in the abnormal expression of

  8. Role of ultrasound biomicroscopy in the planning for secondary implantation of intra ocular lens in aphakia. (United States)

    Elfiky, Mohamed; Saad, Hisham; Elseht, Rabab; Selima, Adel


    Purpose This is a prospective investigational study that was performed at Tanta University Eye Hospital, Tanta, Egypt to evaluate the role of ultrasound biomicroscopy (UBM) in planning secondary implantation of intra ocular lens (IOL) in aphakia. Methods Preoperative UBM was performed for the assessment of anterior segment of 30 aphakic eyes admitted for secondary IOL implantation with special attention to central corneal thickness (CCT), anterior chamber depth (ACD), ciliary sulcus (CS), anatomical changes, and posterior capsular (PC) integrity which had been assessed by measuring the remnants of PC with special attention to the 12, 3, 5, 6, 7, and 9 o'clock meridians. Results This study involved 30 eyes in 27 patients; 16 males and 11 females. The mean age was 8.39 ± 2.36 years. The causes of aphakia were: congenital cataract extraction in14 eyes (46.7 %); trauma in 14 eyes (46.7 %); and after extracapsular cataract extraction in 2 eyes (6.6 %). The mean CCT was 0.61 + 0.35 mm and the mean ACD was 3.03 + 0.41 mm. The ciliary sulcus was patent in 28 eyes (93.4 %). Posterior synechia was observed in 8 eyes (26.7 %), lens remnants in 11 eyes (36.7 %), corneal scars in 11 eyes (36.7 %), and vitreous in anterior chamber in 1 eye (3.3 %). The integrity of PC was illustrated with a diagram. Conclusions UBM is a useful device to evaluate aphakic eyes before secondary IOL implantation through good evaluation of the anterior segment with special attention to the posterior capsular integrity, ciliary sulcus, anterior chamber depth, corneal thickness, and detection of any structural changes in the anterior segment resulting from the remote cause of aphakia.

    Celano, Marianne; Hartmann, E. Eugenie; DuBois, Lindreth G.; Drews-Botsch, Carolyn


    Aim To assess motor functioning in 4.5 year olds enrolled in the Infant Aphakia Treatment Study, and to determine contributions of visual acuity and stereopsis to measured motor skills. Method Children with unilateral aphakia randomized to intraocular lens (IOL) or contact lens (CL) treatment were evaluated at 4.5 years for monocular recognition visual acuity, motor skills, and stereopsis by a traveling examiner masked to treatment condition. Motor skills were assessed with the Movement ABC-2. Visual acuity was operationalized as logMAR value for treated eye, best logMAR value for either eye, and intraocular logMAR difference. Results T-tests showed no significant differences in MABC-2 scores between the IOL and CL groups. The mean total score was low (6.43; 18th percentile) compared to the normative reference group. Motor functioning was not related to visual acuity in the treated eye or to intraocular logMAR difference, but was predicted in a regression model by the better visual acuity of either eye (usually the fellow eye), even after accounting for the influence of age at surgery, examiner, orthotropic ocular alignment, and stereopsis. Interpretation Children with unilateral congenital cataract may have delayed motor functioning at 4.5 years, which may adversely affect their social and academic functioning. PMID:26084944

    Full Text Available Purpose: Evaluation of the results of various treatment tactics of patients with post-traumatic retinal detachment pathology combined with aniridia and aphakia.Patients and methods.The analysis of four clinical cases of surgical treatment of post-traumatic retinal detachment in conjunction with aniridia and aphakia was carried out. There was used a gradual approach of optic-reconstructive surgery: vitreoretinal stage by the standard method 23‑25 Ga with tamponade of vitreous cavity with silicone oil in two different ways. In one case, full eyeball tamponade was made, and in the other one it was made up to the diaphragm formed of polypropylene sutures. At the final stage — iridolenticular diaphragm was implanted (Reper-NN, Russia.Results. In all cases, early postoperative reaction proceeded with the phenomena of fibrino-plastic iridocyclitis, which corresponded to the severity of the initial state and the volume of surgical intervention. Periods of observation of patients in the postoperative period ranged from 3 to 12 months. In three cases where the diaphragm was formed from polypropylene sutures there was noticed full retina adaptation, wherein silicone oil, introduced in the vitreous cavity, did not penetrate into the anterior chamber during the entire period of observation. In one case, where there was a complete eyeball tamponade with silicone oil epithelial and endothelial corneal dystrophy developed. Such an outcome of a clinical case, despite high functional results, is apparently related to the severity of the initial state, the need to re-intervention for recurrent retinal detachment and relatively early stages of iridolenticular diaphragm implantation.Conclusion. Reconstructive surgery of posttraumatic aniridia and aphakia combined with retinal detachment requires a multistage approach. Reconstruction of anterior segment of the eye is preferably to carry out in long-term periods as after the trauma so after surgical treatment

Preoperative data collected included demographics, etiology of aphakia, previous surgeries, preoperative eye pathology, intraocular pressure, clinical signs of endothelial cell loss, and best corrected visual acuity. Operative data and postoperative outcomes included the best corrected visual acuity, lens position, intraocular pressure, pigment dispersion, clinical signs of endothelial cell loss, development of macular edema, and other complications.Results: Thirty-one patients were included. The mean follow-up was 25.2 months (range: 4–48 months. The mean best corrected visual acuity postoperatively was 0.64 logarithm of the minimum angle of resolution (logMAR and varied from 0 logMAR to 3 logMAR. Some patients had a low visual acuity preoperatively because of preoperative eye pathologies. In 22 patients the visual acuity improved, in two patients the visual acuity remained unchanged, and seven patients showed a decreased visual acuity. Complications were peaked pupils (n=10 and retinal detachment in one case. Four patients showed an iris atrophy and high intraocular pressure was observed only in one patient.

    Directory of Open Access Journals (Sweden)

    Umut Duygu Uzunel


    Full Text Available We present a case of transpupillary argon laser cyclophotocoagulation (TALC in a patient with traumatic aniridia and aphakia secondary to blunt trauma who had previous bilateral trabeculectomy. Four months after the trauma the patient’s intraocular pressure (IOP rose to 35 mmHg despite topical antiglaucomatous medication. Inferior 180 degrees cyclophotocoagulation was performed with transpupillary argon laser in the first session and his IOP fell to values of 12-17 mmHg. Twelve weeks after TALC, his IOP rose to 22 mmHg and we had to apply TALC to the residual ciliary processes. Seven months later his IOP was 13 mmHg with topical dorzolamide/timolol and latanoprost administration. TALC may be an effective treatment alternative for lowering IOP in patients with visible ciliary processes who do not respond to conventional medical or laser treatment.

  14. Correlation between clinical data and antibiotic resistance in coagulase-negative Staphylococcus species isolated from 68 patients with acute post-cataract endophthalmitis. (United States)

    Chiquet, C; Maurin, M; Altayrac, J; Aptel, F; Boisset, S; Vandenesch, F; Cornut, P L; Romanet, J P; Gain, P; Carricajo, A


    Coagulase-negative staphylococci (CNS) cause the majority of post-cataract endophthalmitis, which can lead to anatomical and/or functional loss of the eye. This study reports the antibiotic susceptibilities of CNS isolates associated with acute post-cataract endophthalmitis cases and correlates antibiotic resistance with severity and outcome of infection in these patients. Clinical data (initial ocular examination, final prognosis, antibiotic treatment) and the antibiotic susceptibilities of the isolated CNS strains were obtained from 68 patients with post-surgical endophthalmitis recruited during a 7-year period by the FRench Institutional ENDophthalmitis Study (FRIENDS) group. The CNS strains displayed 100% susceptibility to vancomycin, 70% to fluoroquinolones, 83% to fosfomycin, 46% to imipenem and 18% to piperacillin. The most effective antibiotic combinations were fosfomycin plus a fluoroquinolone and imipenem plus a fluoroquinolone, which were considered adequate in 80% and 58% of patients, respectively. Methicillin resistance was significantly associated with older age (p 0.001), diabetes mellitus (p 0.004), absence of fundus visibility (p 0.06), and poor visual prognosis (p 0.03). Resistance to fluoroquinolones was significantly associated with absence of fundus visibility (p 0.05) and diabetes mellitus (p 0.02). This large prospective study demonstrates that methicillin resistance and, to a lesser extent, fluoroquinolone resistance in CNS strains causing postoperative endophthalmitis are both prevalent in France and associated with a poorer visual prognosis. These results emphasize the need for an effective surveillance of this antibiotic resistance and the development of new diagnostic tools for rapid detection for early optimization of antibiotic therapy in endophthalmitis patients.

Two eyes had CME detected only by FFA and one eye only by OCT. The agreement between the two examinations was good (Kappa = 0.7331; p=0.0001 with no tendency to have neither more positive nor negative findings (p=1.0. CONCLUSION: According to these preliminary data, OCT seems to be as effective as FFA to detect CME with a good agreement between the two techniques.OBJETIVO: Avaliar a concordância entre tomografia de coerência óptica (OCT e angiofluoresceinografia (AF no diagnóstico do edema macular cistóide (EMC secundário a cirurgia de catarata. MÉTODOS: Estudo retrospectivo observacional comparativo de 25 olhos com provável EMC. Pacientes com baixa de acuidade visual e alterações na biomicroscopia de fundo após cirurgia de catarata foram submetidos aos exames de OCT e AF na mesma visita. O diagnóstico do EMC foi realizado considerando a presença de vazamento de fluoresceína na angiografia e o espessamento retiniano e/ou espaços cistóides e/ou líquido subretiniano pela OCT. RESULTADOS: Vinte e cinco olhos de 25 pacientes foram avaliados. Vinte e dois olhos mostraram resultados semelhantes no OCT e AF, sendo que 15 olhos apresentaram EMC e 7 olhos não apresentaram EMC. Dois olhos com EMC foram diagnosticados apenas pela AF e um olho apenas pelo OCT. A concordância entre os exames foi boa (Kappa = 0,7331; p=0,0001 sem tendência para achados positivos ou negativos (p=1,0. CONCLUSÃO: Conforme este estudo preliminar, OCT parece ser tão efetiva quanto a AF na detecção do EMC com boa concordância entre os dois métodos.

  9. Surgery for Congenital Cataract


    David Yorston FRCS FRCOphth


    The management of congenital cataract is very different to the treatment of a routine age-related cataract. In adults, surgery may be delayed for years without affecting the visual outcome. In infants, if the cataract is not removed during the first year of life, the vision will never be fully regained after surgery. In adults, if the aphakia is not corrected immediately, it can be corrected later. In young children, if the aphakia is not corrected, the vision will never develop normally.

  15. Anterior chamber fixation of a posterior chamber intraocular lens: A novel technique

    Directory of Open Access Journals (Sweden)

    A Sahap Kükner


    Full Text Available We aimed to evaluate the implantation of a posterior chamber intraocular lens (IOL in the anterior chamber (AC with the haptics passing through two iridectomies to the posterior chamber. A total of 33 eyes of 33 patients with inadequate posterior capsular support due to either previous aphakia or posterior capsular rupture during cataract extraction were included in the study. A double iridectomy was performed on all patients using a vitrectomy probe on the midperiphery of the iris. IOLs were implanted in the AC, and the haptics were passed through the iridectomies to the posterior chamber. The mean follow-up time was 25.3 months. AC hemorrhage occurred in five patients during the iridectomy procedure. Corneal edema was detected in eight of 14 patients with primary IOL insertions. Haptic dislocation was detected in only one patient. This technique may be a good alternative to scleral-fixated IOL implantation in eyes with aphakia.

    Glaucoma surgery can be classified as either cyclodestructive (reducing inflow) or filtering (increasing outflow). Filtration has traditionally been the procedure of first resort because of its efficacy and relative predictability, whereas ciliary destruction has been reserved for more refractory cases of glaucoma and in eyes which have little or no visual potential. Refractory glaucomas include neovascular glaucoma, post-traumatic glaucoma, glaucoma associated with aphakia, severe congenital...

All patients underwent phacoemulsification and intraocular lens implantation. Patients were divided into two equal groups (n = 43 [eyes]: a control group given topical dexamethasone 0.1%, four times/day for 12 weeks postoperatively and a study group given topical ketorolac tromethamine 0.4% twice daily in addition to topical dexamethasone 0.1% four times daily for 12 weeks. Patients were examined at 3, 6, and 12 weeks postoperatively for evaluation of CME development. The main study outcome was the change in the retinal fovea thickness measured with ocular coherence topography.Results: Ten eyes developed CME (11.6%; eight eyes in the control group and only two eyes in the study group. Mean retinal fovea thickness was significantly higher in the control group compared to the study group. Moreover, eyes of the control group developed CME significantly earlier than those of the study group.Conclusion: Prophylactic postoperative ketorolac 0.4% may have a role in reducing the frequency and severity of CME in diabetic eyes post-cataract surgery.Keywords: diabetes mellitus, cataract surgery, central macular edema, ketorolac, dexamethasone

  3. Sir Nicholas Harold Lloyd Ridley: 10 July 1906 - 25 May 2001. (United States)

    Apple, David J


    Sir Harold Ridley invented and refined the modern miracle of replacing lenses obscured by cataracts with plastic optical lenses, thus rendering a complete cataract cure. This operation, broadly termed the cataract-intraocular lens (IOL) operation, has since brought sight to many millions of people throughout the world, and continues to improve the quality of life of more than 10 million patients worldwide each year. Ridley not only launched this powerful and irreversible forward movement in the field of ophthalmology and the visual sciences, but through it he also helped give birth to the exciting and new field of artificial biodevice implantation as well as transplantation techniques now applied to many other organs and tissues of the body. He has therefore been credited with healing to create the relatively new specialty of biomedical engineering. Few of the millions of patients worldwide who now enjoy the benefits of the modern cataract - IOL operation are aware of the origin of this innovation. Indeed, few eye care professionals - even ophthalmic surgeons who implant them almost daily - are aware of the origin of the IOL - an invention that, as Harold himself liked to say, 'cured aphakia'. (The word aphakia comes from teh Greek, meaning absence of lens, the situation that occurs when a cataractous lens is surgically removed.) PMID:18543467

  4. [Results of intraocular lens implantation in cataract complicated by medium and high myopia]. (United States)

    Plotnikova, Iu A; Chuprov, A D; Volkov, D V


    Results of surgical treatment of cataract complicated by medium and high myopia are analyzed. The main group consisted of 90 patients (96 eyes) subjected to extracapsular cataract extraction with implantation of posterior-chamber intraocular lenses and the reference group of 128 patients in whom cataract was extracted without implantation of artificial lens. The study included creation of a mathematical model of myopic eye with estimation of pressure fluctuations in various zones of the eye, developing during transposition of the vitreous during patient's movements (head movements, jumps, falling) and the damping effect of the lens in the ocular system. It was proven by mathematical calculations that transpositions of jelly fractions of the vitreous decreased by 70% in an eye with the lens in comparison with their transposition in aphakia. Clinical studies demonstrated the efficiency of intraocular correction of aphakia in high myopia: implantation of an intraocular lens decreases the risk of detachment of the retina during the postoperative period and helps attain the desired refraction.

  5. A truly knotless technique for scleral fixation of intraocular lenses: Two-year results

    Directory of Open Access Journals (Sweden)

    Naresh K Yadav


    Full Text Available Scleral fixated intraocular lens (SFIOL is a safe and effective option for managing optical aphakia. Suture related complications like suture erosion, suture breakage, endophthalmitis, etc. are unique to SFIOL. The knots can be covered by partial thickness flaps or they can be rotated into scleral tissues without flaps to reduce the complications. We performed a recently described novel technique which obviates the need for knot and scleral flaps in securing the SFIOL. This novel 2-point Ab externo knotless technique may reduce the knot related problems. Twenty-three eyes undergoing this knotless SFIOL procedure were analyzed for intraoperative and postoperative complications. Twenty-two eyes either maintained or improved on their preoperative vision. All patients had a minimum follow-up of 24 months.

    Full Text Available Daniel Gologorsky, Harry W Flynn Jr Department of Ophthalmology, Bascom Palmer Eye Institute, University of Miami Miller School of Medicine, Miami, FL, USA Abstract: Cataract surgery in patients with pathologic myopia and high axial length can be challenging for a variety of reasons, including imprecise intraocular lens calculations in eyes with posterior staphylomas and intraoperative complications such as suprachoroidal hemorrhage, posterior capsular rupture, and retinal tears. Although most surgeons recommend standard phacoemulsification and preservation of the posterior capsule in these cases, an alternative approach presented in this series entails the removal of the lens through the pars plana and removal of formed vitreous during the concurrent procedure.

  7. [The surgical results in traumatic cataract]. (United States)

    Chiseliţă, D; Vancea, P P; Filimon, O; Brănişteanu, D; Bredetean, M; Poiata, I


    The retrospective analysis of the postoperative course in 204 traumatic cataracts (140 isolated, simple cataracts and 64 aggravated ones) showed an apparent functional improvement in the simple cases (preoperative and postoperative visual acuity 0.0139 and 0.8520, respectively); the incidence of postoperative detachment of retina was of 4.9%, that of postoperative endophthalmitis that of cystoid macular edema of 3.2%; complications more commonly occurred in aggravated traumatic cataracts and partially accounted for the poorer functional results. During the investigated interval (1988-1992) a rapid shift to extracapsular cataract extraction and posterior chamber lens implants was made. The crystalline grafts preserved binocular vision in 92% of the cases and contact lens in 50% of the cases. Lens implant remains a matchless solution for the visual rehabilitation of the patients with aphakia. PMID:7654673

  8. A computer model for the evaluation of the effect of corneal topography on optical performance. (United States)

    Camp, J J; Maguire, L J; Cameron, B M; Robb, R A


    We developed a method that models the effect of irregular corneal surface topography on corneal optical performance. A computer program mimics the function of an optical bench. The method generates a variety of objects (single point, standard Snellen letters, low contrast Snellen letters, arbitrarily complex objects) in object space. The lens is the corneal surface evaluated by a corneal topography analysis system. The objects are refracted by the cornea by using raytracing analysis to produce an image, which is displayed on a video monitor. Optically degraded images are generated by raytracing analysis of selected irregular corneal surfaces, such as those from patients with keratoconus and those from patients having undergone epikeratophakia for aphakia.

  9. Conjunctival inclusion cyst following repair of tube erosion in a child with aphakic glaucoma, leading to endophthalmitis

    Directory of Open Access Journals (Sweden)

    Roy, Avik Kumar


    Full Text Available Introduction: Glaucoma in aphakia is a major long term complication following congenital cataract surgery. Implantation of glaucoma drainage device provides an effective approach to manage refractory paediatric glaucoma. However implant surgery in young individuals is not free of complications. The prompt detection and management of tube erosion is of utmost importance to prevent devastating sequel of endophthalmitis. Implantation cyst following repair of tube erosion has not been reported so far. This case illustrates the rare occurrence of inclusion cyst following repair of tube erosion, the possible causes and its consequences. Case description: A 2-year-old child with aphakia developed intractable glaucoma. Following a failed glaucoma filtering surgery he underwent sequential Ahmed Glaucoma Valve implantation in both the eyes. Six weeks following right eye surgery, the child presented with conjunctival erosion overlying the tube, which was treated with scleral patch graft and conjunctival advancement. One month after the repair of tube erosion, the child presented with implantation cyst under the scleral patch graft, which was treated by drainage with a 29G needle. The child presented with endophthalmitis of his right eye following an episode of bilateral conjunctivitis. This was managed by an emergency pars plana vitrectomy, intraocular antibiotics and tube excision. At the last follow up visit, the IOP was 20 mmHg with 2 topical antiglaucoma medications in the right eye following a trans scleral photocoagulation.Discussion: Lifelong careful follow-up of paediatric eyes with implant surgery is mandatory to look for complication such as tube erosion. It is important to place additional sutures to secure the patch graft during implantation of glaucoma drainage devices in children to prevent graft displacement and consequent tube erosion. During repair of tube erosion, it is crucial to remove all the conjunctival epithelium around the tube

    Full Text Available Context: Children admitted in blind schools need low vision assessment for improving functional vision (useful residual vision. Aim: To ascertain the need for spectacles and magnifiers as low vision devices (LVD in children with useful residual vision, attending blind schools. Setting and Design: Cross-sectional study conducted in 13 blind schools in Delhi, North India. Materials and Methods: Of a total of 703 children (less than 16 years of age examined, 133 (18.91% with useful residual vision were refracted and analyzed. High addition plus lenses (range 5-30 diopters were used as spectacle magnifiers for near LVD assessment. "World health organization (WHO/ prevention of blindness (PBL eye examination record for children with blindness and low vision", was used to collect data. SPSS (statistical package for the social science, version 10.0 was used for analysis. Results: Based on the vision of 133 children at initial examination, 70.7% children were blind and 12.0% were severely visually impaired (SVI. 20.3% children improved by at least one WHO category of blindness after refraction. With best correction, 50.4% children were still blind and 13.5% were SVI. Visual acuity in the better eye after refraction in 47 children (35.3%, improved with spectacles. Children with aphakia (17, coloboma (5, refractive error (5 and microphthalmos (4 benefited from spectacles. Of 124 children with low vision but having useful residual vision, 51 (41.1% were able to read N-10 unaided or with distance spectacles and 30 children (22.6% improved to N-10 with spectacle magnifiers and were prescribed the same. Conclusion: Visually impaired children with aphakia and congenital anomalies of the eye benefit from refraction and low vision services.

    Full Text Available Purpose: To compare the outcomes of iris claw anterior chamber intraocular lens (ICACIOL with that of scleral fixation posterior chamber intraocular lens (SF-PCIOL implantation during pars plana vitrectomy (PPV as initial surgery to correct aphakia. Methods: Twelve patients with complicated cataract surgery or trauma who had suffered nucleus, whole crystalline lens or intraocular lens (IOL drop into the vitreous cavity, and undergone PPV with IC-ACIOL implantation over a period of one year were evaluated for the purpose of this study. Uncorrected visual acuity (UCVA, best corrected visual acuity (BCVA, central corneal thickness (CCT, spherical equivalent (SE refractive error, astigmatism and complications were recorded. The results were compared to outcomes of another group of 13 patients who had previously undergone PPV with SF-PCIOL implantation. Results: Mean improvement of UCVA was greater in IC-ACIOL eyes as compared to the SF-PCIOL group (-1.17±0.28 versus -0.89±0.21 logMAR, P=0.01, corresponding values for postoperative BCVA were 0.24±0.17 and 0.44±0.22 logMAR (P=0.041, respectively. Average postoperative SE was comparable in the IC-ACIOL and SFPCIOL groups at 0.6±1.03 and 0.56±1.23 diopters, respectively (P=0.290. However, 10 (83.3% IC-ACIOL eyes versus 6 (46.1% SF-PCIOL eyes had SE within 1 diopter of emmetropia (P=0.048. Mean postoperative increase in CCT was comaparble between the study groups (P=0.126. Conclusion: In the absence of sufficient capsular support, the use of an IC-ACIOL for correction of aphakia during PPV can be a good alternative and seems to entail better visual outcomes as compared to SF-PCIOL.

  12. On the delights of being an ex-cataract patient: Visual experiences before and after cataract operations; what they indicate (United States)

    van Nes, Floris L.


    This paper is about changes in the author's visual perception over most of his lifetime, but in particular in the period before and after cataract operations. The author was myopic (-3D) until the operations, and emmetropic afterwards - with mild astigmatic aberrations that can be compensated with cylindrical spectacles, but in his case rarely are, because of the convenience of not needing to wear distance glasses in daily life anymore. The perceptual changes concern color vision, stereopsis and visual acuity. The post-cataract changes were partly expected, for example less yellow and more blue images, but partly wholly unexpected, and accompanied by feelings of excitement and pleasure; even delight. These unexpected changes were a sudden, strongly increased depth vision and the sensation of seeing suddenly sharper than ever before, mainly at intermediate viewing distances. The visual acuity changes occur after, exceptionally, his distance glasses are put on. All these sensations lasted or last only for a short time. Those concerning stereopsis were dubbed 'super depth', and were confined to the first two months after the second cataract operation. Those concerning acuity were termed 'super-sharpness impression'; SSI. These can be elicited more or less at will, by putting on the spectacles described; but will then disappear again, although the spectacles are kept on. Ten other ex-cataract patients have been interviewed on their post-operation experiences. The 'super-depth' and SSI experiences may be linked to assumed neurophysiological mechanisms such as the concept of Bayesian reweighting of perceptual criteria.

    Full Text Available Abstract Background An observational case series was used to study the virulence characteristics and genotypes of paired Staphylococcus epidermidis isolates cultured from intraocular samples and from periocular environment of patients with postcataract surgery endophthalmitis. Methods Eight S. epidermidis isolates were obtained from three patients (2 from patients #1 and 2 and 4 from patient #3 whose vitreous and/or anterior chamber (AC specimens and preoperative lid/conjunctiva samples were culture positive. Cultures were identified by API-Staph phenotypic identification system and genotypically characterized by Fluorescent Amplified Fragment Length Polymorphism (FAFLP and checked for their antimicrobial susceptibility. The isolates were tested for biofilm-production and methicillin-resistance (MR by PCR amplification of icaAB and mecA gene respectively. Results Four out of eight S. epidermidis strains showed multiple drug resistance (MDR. All the eight strains were PCR positive for mecA gene whereas seven out of eight strains were positive for icaAB genes. In all three patients FAFLP typing established vitreous isolates of S. epidermidis strains to be indistinguishable from the strains isolated from the patient's conjunctival swabs. However, from patient number three there was one isolate (1030b from lid swab, which appeared to be nonpathogenic and ancestral having minor but significant differences from other three strains from the same patient. This strain also lacked icaAB gene. In silico analysis indicated possible evolution of other strains from this strain in the patient. Conclusion Methicillin-resistant biofilm positive S. epidermidis strains colonizing the conjunctiva and eyelid were responsible for postoperative endophthalmitis (POE.

Retrospective analysis of 136 eyes that received a B-K-Pro type 1 between 1999 and 2012 was performed. Five eyes with a diagnosis of exogenous endophthalmitis after B-K-pro type 1 were identified and information about demographic data, indication for K-Pro, post-operative bandage contact lens use, post-operative prophylactic antibiotic use, timing and clinical presentation of endophthalmitis, gram stain and culture results of intraocular fluid and preoperative and post-operative visual acuity were collected. The incidence of endophthalmitis was 3.67% (5 of 136 eyes) and average time to develop endophthalmitis was 5.62 months (range 2 days to 8 months). Mean patient age was 31.4 years (5 to 65 years). The surgical indications included corneal injury due to chemical burns (n = 2), multiple failed grafts secondary to microbial keratitis (n = 2) and congenital glaucoma with congenital herpetic keratitis (n = 1). Post-Boston K-Pro, the visual acuity ranged from light perception (LP) to 20/50. K-pro was explanted in 4 patients. There was bacterial and fungal growth in two patients each and one vitreous did not grow anything. All the eyes were phthisical at last visit. Infectious endophthalmitis after K-Pro implantation in our study had a higher incidence, early onset and extremely poor visual outcome compared with post-cataract surgery endophthalmitis, as reported in literature. Not only bacterial but also fungal infections are an important etiology for infectious endophthalmitis in these cases. PMID:25183460

    Full Text Available Purpose: To assess the accuracy of the potential acuity meter (PAM in predicting postcataract surgery visual acuity outcome in patients with healed inactive maculopathies. Study Design: Prospective interventional clinical trial. Patients and Methods: Patients scheduled for phacoemulsification had preoperative and 1 month postoperative best-corrected visual acuity (BCVA, PAM test, fluorescein angiography, and macular optical coherence tomography. Patients were grouped to following preoperative BCVA: PRE1: 0.29 and better, PRE2: 0.25-0.13, and PRE3: 0.1 or worse; age: G1 70 years. PAM accuracy was divided into: Grade 1: Postoperative BCVA ≤1 or less line error of the PAM score, Grade 2: Between 1 and 2 lines error, and Grade 3: ≥3 lines or more error. Results: This study enrolled 57 patients with a mean age of 71.05 ± 6.78 years where 34 were females. There were 21 (36.84% patients with diabetic maculopathy and 36 (63.16% with age-related macular degeneration. The mean preoperative BCVA was 0.198 ± 0.12 (0.1-0.5. The mean PAM score was 0.442 ± 0.24 (0.1-1.3. The mean postoperative BCVA was 0.4352 ± 0.19 (0.17-1.00. The PAM score was in Grade 1, 2, and 3 in 46 (80.7%, 54 (94.7%, and 56 (98.2, respectively. There was a highly significant correlation between the PAM score and the postoperative BCVA (P < 0.001, Chi-square test. There was no correlation between the PAM test accuracy and age, gender, diagnosis, and preoperative BCVA (P = 0.661, 0.667, 0. 0.991, 0.833, Chi-square test; respectively. Conclusion: The PAM is an accurate method of predicting postoperative visual acuity for eyes with nuclear cataracts Grade I and II and inactive maculopathies.

  19. Pitfalls in aphakic contact lens fitting

    Directory of Open Access Journals (Sweden)

    Dada Vijay


    Full Text Available We examined 23 consecutive cases of unilateral aphakia reporting to the contact lens office for endothelial count and morphology, corneal thickness and toricity. The fellow eye served as a control in all the cases. It was found that there is a significant drop in the central endothelial cell density, and change in the size and shape of the cells. These observations indicate a thermodynamically unstable state. The aphakic corneas were thicker than the controls but not to a significant extent. The cell count and pachymetry had no statistical correlation. Toricity of the aphakic corneas make successful fitting of a lens difficult. Since prolonged use of extended wear gas permeable as well as hydrogel lenses have a deleterious effect on the endothelium it is suggested that a careful case selection be made and strict monitoting carried out at follow up. These corneas are liable for decompensation with only mild noxious stimuli. This article is intended to acquaint the ophthalmologist with the pitfalls in aphakic contact lens fitting so that a cautious follow up may be planned.

    Full Text Available Purpose: The purpose of this study was to evaluate the clinical efficacy and safety of modified posterior chamber intraocular lens (PCIOL implantation with transscleral fixation. Design and Setting: This is a study, which is conducted at Department of Ophthalmology, Jinan Eye Hospital, Jinan Second People′s Hospital. Materials and Methods: A total of 82 patients who were scheduled for sutured PCIOL were divided randomly into modified and conventional groups. The former underwent PCIOL through pars plana fixation with knot buried and without scleral flap and the latter underwent transscleral fixation of PCIOL in the ciliary sulcus. The main outcome measures included operative time, postoperative visual acuity, and postoperative complications. Results: The mean operative time of the modified group was 39.95 ± 5.87 min, which was significantly less than that of the conventional group (45.77 ± 5.21 min; P < 0.05. No difference was found in postoperative visual acuity between the two groups. There were no significant postoperative complications, including knot exposure, endophthalmitis, and retinal detachment in either group. The optical clamping of PCIOL was prone to occur in the conventional group. Conclusion: Modified sutured PCIOL implantation is a safe, effective, and feasible technique for the correction of aphakia in eyes without adequate posterior capsular support.

  1. Optical explanation of the gradual disappearance of flying dots in posterior vitreous detachment. (United States)

    Serpetopoulos, C


    It is well-known that flying dots (muscae volitantes) in posterior vitreous detachment gradually disappear. An analogy for this phenomenon is the optical effect of planets casting conic shadows as they are lighted by the sun (in this case the pupil serves as the light source) and these shadows shrink as the planets near the sun. When the opacities move forward in the vitreous cavity, their shadows are not long enough to reach the retina, so the flying dots disappear. They can also disappear when their shadows fall on the optic disk or when they are mixed with the random pattern of bright and dark areas of the retinal image in ordinary conditions. Pupil dilatation makes the conoid shadow shorter; thus, the flying dots became fainter. In advanced cataract, stray light makes the retinal image less sharp, reducing the perception of dots. Replacement of the opacified lens by an intraocular lens restores the sharpness of the retinal image, because the light entering the eye becomes less diffuse, making the flying dots more obvious. The same reasoning explains similar phenomena in aphakia and large ametropias with and without corrective spectacles, as well as opacities of any etiology in the vitreous. PMID:9265706

  2. Mouse models of congenital cataract. (United States)

    Graw, J


    Mouse mutants affecting lens development are excellent models for corresponding human disorders. The mutant aphakia has been characterised by bilaterally aphakic eyes (Varnum and Stevens, J Hered 1968;59:147-50); the corresponding gene was mapped to chromosome 19 (Varnum and Stevens, Mouse News Lett 1975;53:35). Recent investigations in our laboratory refined the linkage of 0.6 cM proximal to the marker D19Mit10. Several candidate genes have been excluded (Chuk1, Fgf8, Lbp1, Npm3, Pax2, Pitx3). The Cat3 mutations are characterised by vacuolated lenses caused by alterations in the initial secondary lens fibre cell differentiation. Secondary malformations develop at the cornea and iris, but the retina remains unaffected. The mutation has been mapped to chromosome 10 close to the markers D10Mit41 and D10Mit95. Several candidate genes have been excluded (Dcn, Elk3, Ldc, Mell8, Tr2-11). The series of Cat2 mutations have been mapped close to the gamma-crystallin genes (Cryg; Löster et al., Genomics 1994;23:240-2). The Cat2nop mutation is characterised by a mutation in the third exon of Crygb leading to a truncated gamma B-crystallin and the termination of lens fibre cell differentiation. The Cat2 mutants are interesting models for human cataracts caused by mutations in the human CRYG genes at chromosome 2q32-35. PMID:10627821

  3. Photobinding of 3H 8-methoxypsoralen to monkey intraocular tissues

    International Nuclear Information System (INIS)

    Young (less than 1 year) and old (greater than 15 years) Rhesus monkeys were utilized in this study in order to determine whether ultraviolet (UV) radiation at ambient levels induces psoralen photobinding in primate eyes (in particular the lens and retina). Unilateral aphakia or pseudophakia was induced surgically and the eyes were allowed to heal. The animals then were given a single intraperitoneal injection of 3H 8-methoxypsoralen (8-MOP) and immediately exposed to BLB lights (of measured radiation intensity at the corneal surface). The animals were killed at varying time periods (2-6 weeks), and the eyes were removed immediately. One-half of each cornea and lens was frozen for subsequent optical spectroscopy and the remaining ocular tissues were fixed for histopathologic studies and autoradiography. These data demonstrate that low level UV radiation (less than 0.4 mW/cm2) can cause 8-MOP photobinding to lens proteins and DNA and to aphakic, pseudophakic, and young phakic primate retinas. The older phakic primate lens serves as a protective UV filter and prevents psoralen photobinding within the retina. These data suggest that older aphakes and pseudophakes may require UV radiation protection to prevent direct as well as photosensitized retinal photodamage

    Purpose: To assess the visual outcome after cataract surgery in a south Indian population. Materials and Methods: Population-based cross-sectional study of subjects aged 40 years or more. Three thousand nine hundred and twenty-four rural subjects from 27 contiguous villages and 3850 urban subjects from five randomly selected divisions were studied. All subjects underwent a comprehensive ophthalmic examination that included visual acuity, refraction, slit-lamp biomicroscopy, applanation tonometry, gonioscopy, and dilated retinal examination. Statistical Analysis: Chi square test, t test and multivariate analysis were used. Results: Five hundred and twenty-eight (216 males, 312 females, 781 eyes) rural subjects (13.5%, 95% confidence interval (CI) 12.4% to 14.6%) and 406 (197 males, 209 females, 604 eyes) urban subjects (10.5%, 95% CI 9.6-11.5%) had undergone cataract surgery. Outcome of cataract surgery was defined based on visual acuity. Using best-corrected visual acuity for classification, the single most important cause for visual impairment was cystoid macular edema in the aphakic group and posterior capsule opacification in the pseudophakic group. Aphakia (visual acuity of visual acuity of visual acuity of visual acuity of visual impairment. The urban cataract-operated population had significantly more pseudophakics (P visual impairment. Conclusions: Surgery-related complications were major causes for visual acuity of <20/60. PMID:20413926

  5. Intraocular lenses and clinical treatment in paediatric cataract

    Directory of Open Access Journals (Sweden)

    Camila Ribeiro Koch Pena


    Full Text Available Pediatric cataract is the most common treatable cause of blindness in children. Prevalence, etiology and morphology vary with the socioeconomic development. The treatment goal is to reduce amblyopia, being difficult management especially in unilateral cases. The decision on aphakia or primary intraocular lens should be individualized as well as correction with contact lens or spectacles. The intraocular lens single-piece hydrophobic acrylic are the most implanted in children and the preferably is in the capsular bag. The Sanders-Retzlaff-Kraff theoretic (SRK/T stressing that is described as more predictable, following Holladay I and SRK II and the recommendation is to under correction +6.0 or +8.0 dioptrias expecting the growth of the eye. The posterior capsule opacity is the most frequent complication and varies with the material choice of the lens. Glaucoma is the most serious postoperative complication and depends on the timing of the surgery, primary lens implantation and time of post surgical follow-up. The adherence to occlusion therapy with patching is critical to the visual prognosis and is determined by the child’s age and laterality of the cataract. There was significant improvement in the surgery and in IOLs, however the final visual prognosis is still not desirable.

    Khokhar, Sudarshan; Gupta, Shikha; Tewari, Ruchir; Agarwal, Renu; Gogia, Varun; Sinha, Gautam; Agarwal, Tushar


    Cataract surgery in eyes with microcornea is associated with frequent complications such as corneal edema, posterior capsular rent, and risk of unplanned aphakia. We describe an improved surgical technique for the creation of surgical incisions during phacoemulsification in eyes with cataract associated with microcornea. A retrospective analysis of eight patients (8 eyes) operated at our center was undertaken. The mean age of the patients was 29.5 ± 10.9 years. All eyes were operated using the scleral pocket incision for phacoemulsification. This scleral pocket incision was tangential to the limbus and created approximately 2.5 mm behind limbus through which phacoemulsification probe was inserted. Because of the posterior placement of incision, the anterior chamber crowding was minimized. There was no incidence of port-site peripheral corneal edema. Fifty percent eyes developed transient central corneal edema, the intraocular lens in bag was implanted in 5/8 eyes, and none developed Descemet's membrane detachment. Mean best-corrected visual acuity improved from 1.85 ± 0.38 logarithm of minimum angle of resolution (LogMAR) to 1.26 ± 0.70 LogMAR postoperatively (P = 0.01; paired t-test). Posterior incision placement during phacoemulsification in microcornea helps achieve favorable postoperative outcomes in contrast to outcomes using clear corneal approach described in literature.

    Full Text Available Background: The northeastern region (NER of India is geographically isolated and ethno-culturally different from the rest of the country. There is lacuna regarding the data on causes of blindness and severe visual impairment in children from this region. Aim: To determine the causes of severe visual impairment and blindness amongst children from schools for the blind in the four states of NER of India. Design and Setting: Survey of children attending special education schools for the blind in the NER. Materials and Methods: Blind and severely visually impaired children (best corrected visual acuity < 20/200 in the better eye, aged up to 16 years underwent visual acuity estimation, external ocular examination, retinoscopy and fundoscopy. Refraction and low vision workup was done where indicated. World Health Organization′s reporting form was used to code anatomical and etiological causes of visual loss. Statistical Analysis: Microsoft Excel Windows software with SPSS. Results: A total of 376 students were examined of whom 258 fulfilled the eligibility criteria. The major anatomical causes of visual loss amongst the 258 were congenital anomalies (anophthalmos, microphthalmos 93 (36.1%; corneal conditions (scarring, vitamin A deficiency 94 (36.7%; cataract or aphakia 28 (10.9%, retinal disorders 15 (5.8% and optic atrophy 14 (5.3%. Nearly half of the children were blind from conditions which were either preventable or treatable (48.5%. Conclusion: Nearly half the childhood blindness in the NER states of India is avoidable and Vitamin A deficiency forms an important component unlike other Indian states. More research and multisectorial effort is needed to tackle congenital anomalies.

    Full Text Available Purpose: To evaluate the effect of silicone oil (SO on the corneal endothelium in SO filled phakic and pseudophakic vitrectomizied eyes. Methods: This prospective comparative consecutive case-control study evaluated the corneal endothelial characteristics of 64 SO filled vitrectomizied eyes (case group as compared to 46 vitrectomizied eyes without SO injection (control group. Endothelial cell densities (ECD, coefficient of variation (CV, and percentage of hexagonal cells (hexagonality at the corneal center were evaluated preoperatively, 1 month and 6 months after surgery using noncontact specular microscopy and were compared between the two groups. Exclusion criteria were previous vitreoretinal surgery, aphakia, any degree of anterior chamber inflammation, SO bubbles in the anterior chamber and increased intraocular pressure in the postoperative period. Results: Six months after SO injection, mean ECD was 2,438.2±327.6 cell/mm 2 in the case group and 2,462.6±361.7 cell/mm 2 in the control group (P = 0.714 and mean hexagonality was 49.6 ± 6.8 and 54.6 ± 8.9, in the case and control groups, respectively (P = 0.004. Six months after operation, CV in the case group was 39.3 ± 5.6 and that in the control group was 35.7 ± 6.4 (P = 0.003. Conclusion: Although the presence of SO in the vitreous cavity of phakic and pseudophakic eyes causes slight reduction in the number of endothelial cells, however it leads to significant changes in endothelial cell morphology. Thus, removal of SO after reaching the desired tamponade effect is recommended.

    İbrahim Tuncer


    Full Text Available Objectives: To compare the results of scleral buckling surgery with and without use of operating microscope for primary rhegmatogenous retinal detachment (RRD. Materials and Methods: This comparative study consisted of 74 eyes of 74 patients who underwent scleral buckling for primary RRD. Group 1 consisted of 35 patients (17 male and 18 female who were operated using operating microscope and Group 2 consisted of 39 patients (19 male and 20 female who were operated without operating microscope. Patients with post-equatorial breaks, retinal breaks greater than 90°, proliferative vitreoretinopathy (≥C2, and those with follow-up period of less than sıx months were excluded from the study. The two groups were compared based on age, sex, etiology, anatomic success, and surgical complications (scleral perforation, iatrogenic retinal breaks, vitreous hemorrhage, buckle malposition, and vortex vein damage. Results: Mean age was 64.11±7.91 years (range, 55-79 years in Group 1 and 65.20±6.15 years (range, 56-80 years, in Group 2. Mean age and gender were not statistically significantly different between the groups (p=0.508 and p=0.990, respectively. Etiological causes were revealed as myopia, peripheral retinal degeneration, pseudophakia, aphakia, trauma, and idiopathic. Etiological causes were not significantly different between the two groups (p>0.05, for all. Surgical complication rates were higher in Group 2, however, the differences were not statistically significant (p>0.05, for all. Anatomical success rates was similar between the two groups (80% in Group 1 and 79.5% in Group 2, p=0.956. Conclusion: The results of scleral buckling surgery with and without use of operating microscope were not significantly different; However, operating microscope should be used especially in presence of risk factors for scleral complications.

    To determine the changes in visual acuity in patients undergoing Trans-Scleral Sutured Posterior Chamber Intra-Ocular Lens (TSSPCIOL) implantation at a tertiary care hospital in Karachi, Pakistan. Study Design: Case series. Place and Duration of Study: LRBT Tertiary Eye Hospital, Karachi, from January 2006 to December 2010. Methodology: Records of all patients undergoing implantation of TSSPCIOL were reviewed. Patients with diagnosed glaucoma, diabetic retinopathy, macular degeneration, history of recurrent uveitis, corneal haze or central corneal scars were excluded. For the final analysis, 70 eyes out of a total of 75 were selected. Main outcomes of interest were pre and postoperative visual acuities and surgical complications. SPSS 21 was used for data analysis. Results: Pre-operatively, the average Best Spectacle-Corrected Visual Acuity (BSCVA) was 6/36 on the Snellen chart. This improved to 6/12 postoperatively. The mean improvement seen was 2.4 lines on the Snellen chart (p < 0.05). Complications include transient intraocular pressure elevation in 25 eyes (36%), IOL tilt in 4 eyes (7.1%), Cystoid Macular Edema (CME) in 4 eyes (5.7%), vitreous haemorrhage in 2 eyes (2.9%), hyphema in 2 eyes (2.9%), uveitis in 1 eye (1.4%), and retinal detachment 1 eye (1.4%). No IOL subluxation, suture erosion, iris capture, choroidal effusion or endophthalmitis was encountered and no re-operations were needed. Conclusion: TSSPCIOLs are a good management option for patients with aphakia in whom PC IOLs cannot be placed. (author)

    Full Text Available ABSTRACTPurpose:To assess the ability of spectral domain optical coherence tomography (SD-OCT to diagnose macular changes pre- and post-cataract surgery and to identify changes in central foveal thickness (CFT relative to age, sex, and presence of concomitant ophthalmic pathologies, for a period of 6 months post-surgery.Methods:A prospective study of patients evaluated by SD-OCT within 5 h before surgery at 7, 30, 60, 90, and 180 days post-op, with respect to CFT and presence of maculopathy.Results:Ninety-eight eyes of 98 patients were evaluated, with the following mean results: age = 71.4 years, pre-op VA = 0.27 logMAR, and final VA = 0.73 logMAR. There were 21 eyes in patients with diabetes mellitus (DM and 10 eyes with age-related macular degeneration (AMD, three with epiretinal membrane, and four with glaucoma. Sixty eyes had no other ophthalmic-related pathologies (NOO, and had a mean pre-op CFT of 222 μm, which progressively increased up to the 60thday post-op, reaching a mean of 227.2 μm. No pseudophakic cystoid macular edema was observed. The mean CFT was statistically significantly different (p<0.001 between NOO and diabetic patients from 30 days post-op. Four eyes presented with preoperative diagnosis of AMD as measured by ophthalmoscopy. After completion of the OCT, which was performed within 5 h before surgery, six additional patients were found to have AMD. Of the 98 total eyes, 10 were diagnosed with maculopathy only by OCT exam. Binocular indirect ophthalmoscopy (BIO was unable to detect such changes.Conclusion:OCT diagnosed preoperative maculopathies in 21.4% of the patients, and was more effective than BIO (11.2%. OCT showed a progressive increase in CFT in diabetics up to 180 days post-operatively, as well as greater CFT in male patients and patients older than 70 years.

    Using high luminance point-of-light stimuli, Vernier judgments can be made in the presence of markedly degraded retinal imagery. Without coaching, observers perform center-of-gravity assessments of relative locations of degraded point images. We seek to defined, presurgery, individuals who will derive the most benefit from advanced cataract removal (a form of triage), and to determine which of two cataractous eyes has the better postsurgical visual prognosis. There are incredible and growing backlogs of patients with severe cataracts (and other dense media opacities) in the developing world, and generally, limited resources are available for provision of health care. Postcataract surgical failure rates for good visual function are often high, and only one eye is operated on in over 95% of indigent patients treated. Prior to initiating advanced studies in the developing world, at Berkeley we conducted preliminary research on Vernier acuity test techniques on normal adult subjects. We sought to determine the number of repeat trials necessary; to compare a two-point and a three-point Vernier display; to determine the shape of the measured response function at large gap separations between test points (required when testing advanced cataract patients); to assess the effect(s) of a broad range of uncorrected refractive errors on outcomes; and to consider means to minimize refraction-based errors. From these and prior data and analyses, we defined a protocol for use in the developing world. Using a newly designed and rugged precision instrument, these tests were repeated on an advanced cataract population at Aravind Eye Hospital in Madurai, India. Although we had much prior experience in India, the initial protocol required major revision on site. Necessary changes in test methods and analytical approaches were made, and next stages in this program were planned. And a new and simple gap `visual acuity' (gap `VA') test was added to the protocol, which greatly facilitated

    Periasamy Sundaresan

    Full Text Available OBJECTIVE: We investigated whether previously reported single nucleotide polymorphisms (SNPs of EPHA2 in European studies are associated with cataract in India. METHODS: We carried out a population-based genetic association study. We enumerated randomly sampled villages in two areas of north and south India to identify people aged 40 and over. Participants attended a clinical examination including lens photography and provided a blood sample for genotyping. Lens images were graded by the Lens Opacification Classification System (LOCS III. Cataract was defined as a LOCS III grade of nuclear ≥4, cortical ≥3, posterior sub-capsular (PSC ≥2, or dense opacities or aphakia/pseudophakia in either eye. We genotyped SNPs rs3754334, rs7543472 and rs11260867 on genomic DNA extracted from peripheral blood leukocytes using TaqMan assays in an ABI 7900 real-time PCR. We used logistic regression with robust standard errors to examine the association between cataract and the EPHA2 SNPs, adjusting for age, sex and location. RESULTS: 7418 participants had data on at least one of the SNPs investigated. Genotype frequencies of controls were in Hardy-Weinberg Equilibrium (p>0.05. There was no association of rs3754334 with cataract or type of cataract. Minor allele homozygous genotypes of rs7543472 and rs11260867 compared to the major homozygote genotype were associated with cortical cataract, Odds ratio (OR = 1.8, 95% Confidence Interval (CI (1.1, 3.1 p = 0.03 and 2.9 (1.2, 7.1 p = 0.01 respectively, and with PSC cataract, OR = 1.5 (1.1, 2.2 p = 0.02 and 1.8 (0.9, 3.6 p = 0.07 respectively. There was no consistent association of SNPs with nuclear cataract or a combined variable of any type of cataract including operated cataract. CONCLUSIONS: Our results in the Indian population agree with previous studies of the association of EPHA2 variants with cortical cataracts. We report new findings for the association with PSC which is

    Objective To report visual outcomes, complication rate, and safety of retropupillary iris-claw intraocular lens (ICIOL) in ectopia lentis in Marfan syndrome (MFS). Design Retrospective study. Methods Six eyes of three MFS patients with ectopia lentis underwent surgery for subluxation lens and retropupillary ICIOL implantation from October 2014 to October 2015 at the Department of Ophthalmology, Santa Maria Hospital in Lisbon, Portugal. Demographics, preoperative and postoperative best-corrected visual acuity (BCVA), and intraocular pressure were evaluated. Endothelium cell count was assessed using specular microscopy; anterior chamber depth was measured using Pentacam postoperatively; and intraocular lens position was viewed by ultrasound biomicroscopy. All patients were female; mean age was 20±14.264 years (range: 7–38 years). Results The average follow-up period was 6.66 months (range: 4–16 months). Preoperative BCVA was 0.568±0.149 logMAR units, and postoperative BCVA was 0.066±0.121 logMAR units. The mean BCVA gain was −0.502±0.221 on the logMAR scale. Postoperative average astigmatism and intraocular pressure were 1.292±0.697 mmHg (range: 0.5–2.25 mmHg) and 16 mmHg (range: 12–18 mmHg), respectively. The average endothelial cell density decreased from 3,121±178 cells/mm2 before surgery to 2,835±533 cells/mm2 after surgery (measured at last follow-up visit) and in the last follow-up, representing an average endothelial cell loss of 9.16%. Mean anterior chamber depth was 4.01 mm (±0.77 mm), as measured by Pentacam. No complications were found intra- or postoperatively in any of the six studied eyes. Conclusion Retropupillary ICIOL implantation is a safe and effective procedure in the treatment of aphakia in MFS eyes, without capsular support after surgery for ectopia lens. The six eyes that underwent lensectomy and retropupillary ICIOL implantation have had excellent visual outcomes with no complications so far. PMID:27382335

    vitrectomy with a transconjunctival technique using the TSV-25 Millennium system. METHODS: Twenty consecutive patients (20 eyes that underwent transconjunctival vitrectomy with the TSV-25 Millennium system, between July 2003 and January 2004, were prospectively postoperatively followed for a minimum period of one month. Eyes with macular hole, epiretinal membrane, macular edema, rhegmatogenous retinal detachment, endophthalmitis, and vitreous hemorrhage with or without tractional retinal detachment were included. Intra and post-operative complications and difficulties were recorded. RESULTS: All 20 patients completed at least one month postoperative follow-up. There were 4 macular holes, 2 epiretinal membranes, 2 cystoid macular edemas post-cataract surgery, 1 diabetic macular edema, 5 rhegmatogenous retinal detachments, 5 vitreous hemorrhages (2 associated with tractional retinal detachment, and 1 endophthalmitis. Mean postoperative day one intraocular pressure was 15.7 mmHg (6 - 46 mmHg and at one postoperative month it was 14.2 mmHg (8 - 22 mmHg. There were no cases of sclerotomy-related retinal breaks, postoperative endophthalmitis, or ocular hypotony. Three of 5 eyes (60% with retinal detachment needed further surgical intervention (all pseudophakic and 4 of 5 eyes (80% with vitreous hemorrhage had postoperative residual hemorrhage. All cases with macular diseases and phakic retinal detachments were successful with one surgery. CONCLUSION: This transconjunctival vitrectomy technique showed as its main benefits the low incidence of sclerotomy-related breaks and postoperative ocular hypertension. An adequate case selection seems to be crucial.
