The aim of the study was to investigate the presence of Demodex in the hair follicles of eyelashes and their potential participation in the aetiology of chalazion in patients in Poland. The study of the correlation between the presence of Demodex spp. and chalazion has never been performed in patients in Europe. There is, therefore, a justified necessity to check whether Demodex mites can be a potential risk factor in the development of chalazion in the European population. The samples were examined by light microscope, using standard parasitological methods. A positive result was assumed in the presence of Demodex spp. Demodex was detected in 91.67% of patients with a chalazion. The presence of Demodex was found in subjects from all examined age groups. The results of statistical analysis unambiguously determined the existence of an interrelationship between the presence of Demodex and chalazion. Our results clearly indicate the existence of a correlation between the occurrence of Demodex spp. and chalazion. Confirmation of the positive correlation between Demodex and chalazion in a European population provides further evidence for the pathogenic role of Demodex in the development of eye diseases.

The patient was a 73-year-old man who had had a nodule on the left lower eyelid for two years. He was referred to our hospital with a diagnosis of a swollen chalazion. The clinical and histopathological records were reviewed and the mass was excised. Histopathological examination revealed a mucinous sweat gland adenocarcinoma. Postoperative magnetic resonance imaging and positron emission tomography excluded systemic metastases. After the histopathological findings, a complete surgical excision of the margins of the adenocarcinoma was performed, with histopathological confirmation of negative margins. After the final histopathological examination, the patient was diagnosed with a primary mucinous sweat gland adenocarcinoma of the left eyelid. Six months after the surgery, no recurrence has been observed. Because the appearance of mucinous sweat gland adenocarcinoma of the eyelid is quite variable, the final diagnosis can only be made by histopathological examination. A complete surgical excision is recommended.Keywords: complete surgical excision, eyelid, initial stage, mucinous sweat gland adenocarcinoma
Full Text Available BACKGROUND Children are affected by various eye disorders like refractive error, eye infections, and squint. Uncorrected refractive errors are a common, but avoidable problem. The presence of uncorrected refractive error in children has a considerable impact on their physical, mental, and behavioural development. Early detection and timely intervention can improve a child’s potential tremendously during the formative years. AIM To find out the magnitude of ocular morbidities among school children of Thoubal, a rural District of Manipur and the type of refractive error prevalent in that region. METHODS A cross sectional study was conducted among school children of Thoubal, a rural area of Manipur. Excluding absentees and non-responders, students were examined by trained Ophthalmologists and Ophthalmic Assistants. Visual acuity was assessed in all students using Snellen’s chart and refraction performed when required. Patients with no improvement by the above method were further examined at the tertiary hospital. Data was tabulated and analysed. RESULTS A total of 1700 students aged from 5 to 15 were examined out of which 53% were boys and 47% girls. Prevalence of ocular morbidity was 17.7% of which refractive error was found in 16.4%, cataract in 0.1%, squint in 0.1%, corneal opacity in 0.1%, chalazion/stye in 0.4%, conjunctivitis in 0.3%, and blindness in 0.1%. A significant proportion of girls suffer from refractive error (57% as compared to boys (43%. Refractive errors prevail highest among the age group 10-12 years. Astigmatism was the most common refractive error (48% followed by Myopia (34% and Hypermetropia (18%. CONCLUSION The study concludes that vision screening in school children is very useful in early detection of refractive errors and other ocular morbidities leading to early treatment and prevention of development of visual disability and amblyopia as most of the children were unaware of the problem.

Cutaneous leishmaniasis is regarded as a re-emerging disease due to its increase in spread and rate of transmission over the past decade due to a proportionate increase in global human movements. This study was therefore carried out to review epidemiology, laboratory diagnosis and treatment with in-depth discussion on some of the rare clinical presentations of the disease capable of influencing its control. The study was based on literature review on clinical and laboratory features of cutaneous leishmaniasis from original research articles, review articles, short communications, letters to editor and case reports on the disease for the past10 years (April 2000to April 2010). The results were analysed using simple descriptive methods. The rarest presentations of leishmaniasis encountered were peritibial ulcerations, hard painful nipple in a male, swollen upper lip, dermatofibro sarcoma protuberans, sternal proliferative growth, turban tumour, post operative granuloma, chalazion-like0.00%, and cutaneous sterile pyogranuloma with asymmetrical alopecia0.00% each. Others include infected sebaceous cysts0.45%, syphilis 0.19%, yaws0.13%, thrombotic ulcerations0.40%, mycetoma 0.90%, sarcoidosis0.67%, painless nasal solitary nodule0.00%, tuberculous lymphadenopathy0.25% and unilateral erythema nodosum0.28%. Physicians practicing in cutaneous leishmaniasis endemic, but most especially in the non-endemic areas should bear in mind that the disease may not be that rare in the context of the present global village phenomenon; and that, the next case could just be that of cutaneous leishmaniasis, the clinical picture of the patient notwithstanding.

Full Text Available When acute inflammation in anterior eye segment of a forward piece of an eye was stopped, ophthalmologists face a problem of absence of acute inflammation signs and at the same time complaints to the remain discomfort feelings. It causes dissatisfaction from the treatment. The complaints are typically caused by disturbance of tears productions. No accidental that the new group of diseases was allocated — the diseases of the ocular surface. Ocular surface is a difficult biologic system, including epithelium of the conjunctiva, cornea and limb, as well as the area costal margin eyelid and meibomian gland ducts. Pathological processes in conjunctiva, cornea and eyelids are linked with tears production. Ophthalmologists prescribes tears substitutions, providing short-term relief to patients. However, in respect that the lipid component of the tear film plays the key role in the preservation of its stability, eyelids hygiene is the basis for the treatment of dry eye associated with ocular surface diseases. Eyelids hygiene provides normal functioning of glands, restores the metabolic processes in skin and ensures the formation of a complete tear film. Protection of eyelids, especially the marginal edge from aggressive environmental agents, infections and parasites and is the basis for the prevention and treatment of blepharitis and dry eye syndrome. The most common clinical situations and algorithms of their treatment and prevention of dysfunction of the meibomian glands; demodectic blepharitis; seborrheic blepharitis; staphylococcal blepharitis; allergic blepharitis; barley and chalazion are discussed in the article. The prevention keratoconjunctival xerosis (before and postoperative period, caused by contact lenses, computer vision syndrome, remission after acute conjunctiva and cornea inflammation is also presented. The first part of the article presents the treatment and prevention algorithms for dysfunction of the meibomian glands, as well as

Full Text Available Aim: To present three patients with ocular disease who developed a range of complications following use of traditional medications. Settings and Design: Case series Methods: Three patients who were examined in the Ophthalmic department of a tertiary care teaching hospital in the Sultanate of Oman between 2003 and 2004, seeking care following use of traditional medicines and or healing practices for various ophthalmic problems described below. Results: The first patient was a computer professional with a chalazion; the patient used a plant extract from ′Calotropis procera′ as a part of the treatment. He developed corneal edema with decrease in vision in his left eye following application of the plant extract. Treatment with topical steroids and antibiotics resulted in a complete clinical and visual recovery. The second patient developed a fungal corneal ulcer (dermatophyte - Trichophyton mentagrophyte after sustaining injury with an animal tail to the right eye and used honey for pain relief prior to presentation. She responded poorly to anti-fungal treatment, underwent a penetrating keratoplasty with recurrence of infection in the graft that resulted in a vascularized corneal scar. The third patient was a five-year-old child who was treated with ′wasam′ on the occiput for intraocular inflammation following bilateral uncomplicated cataract extraction. Following this treatment the topical steroid was discontinued. The "Wasam" treatment indirectly resulted in exacerbation of the intraocular inflammation and secondary glaucoma and poor vision as well as ′Wasam ulcers′ on the occiput. Despite treatment of the intraocular inflammation, the visual outcome was poor. Conclusion: Traditional medicine in Oman is sought by many for variable reasons. Lack of evidence-based scientific data on its safety or efficacy does not deter the Omanis from flocking the traditional healers. However, when applied in the treatment of ocular diseases
