Introduction: Pterygium is a centripetal proliferation of fibrovascular tissue, which proceeds from the bulbar conjunctiva towards the center of the cornea. Excision of the pterygium may cause visual acuity improvement and surgical excision aims to achieve a topographically regular ocular surface. The improvement of the visual acuity results from the alteration of the refractive corneal power, that is measured in the topography as alteration of the topographic astigmatism. The objective of this study was to evaluate the variation of the […]

OBJECTIVE: To evaluate the surgical technique for excision of primary pterygium with fibrin glue, as the symptoms and epidemiological data. METHODS: Clinical prospective non-controlled and randomized study with 30 patients of the Hospital Universitário Lauro Wanderley, consistent with the term informed consent, approved by the Ethics in Research. The surgeries were evaluated at 1, 7 and 21 postoperatively (PO). RESULTS: Of the 30 operated patients, 16 (53,3%) were female, aged 21-67 years (42.2). As for the degrees of pterygium (1-3): […]

OBJECTIVE: This study aims at observing the inhibition of cell proliferation in primary pterygium by the use in vitro of mitomicyn C, cyclophosphamide, methotrexate. METHODS: Pterigyum was removed from seven pacients between 30 and 60 years and were submitted to culture of epithelial cells. Later the effect of drugs was tested on the cells: cyclophsphamide, methotrexate, mitomicyn. The cells were observed for five days under the microscope to assess cellular proliferation, and the experiments were repeated five times RESULTS: When […]

OBJETIVO: Este é um estudo clínico oftálmico transversal para estimar a prevalência e gravidade de pterígios em uma população específica na bacia Amazônica, Brasil. MÉTODOS: O estudo incluiu 225 indivíduos acima de 20 anos de idade, oriundos de três diferentes residências na cidade de Manaus (grupo 1, n = 89), comunidades ribeirinhas (grupo 2, n = 116) e indígenas que habitam nas florestas (grupo 3, n = 20). Pterígios foram classificados de 1-4 pelo exame com tocha e determinando-se sexo, […]

OBJECTIVE: This is a cross sectional ophthalmic clinic-based study to estimate the prevalence and severity of pterygium in a selected population in the Amazon Basin, Brazil. METHODS: The study included 225 subjects above 20 years age from three different places of residence of Manaus city (group 1, n=89), river based communities (group 2, n= 116) and indigenous rainforest inhabitants (group 3, n=20). Pterygia was graded 1-4 by torch examination and gender, age and occupation determined. RESULTS: were assessed to have […]

OBJETICVE: The authors describes a surgical technique that utilizes autologus delaminated scleral graft for the management of deep scleral ulcers. METHODS: In this technique that were perfomed in 12 eyes of 12 patients, 9 female, 3 male, age from 48 to 82 years, mean age 65.2 years. RESULTS: Occurred good integration of the grafting in all cases without any complications. CONCLUSION: Many techniques have been proposed for the management of scleral ulcers: sclera and dura-mater, autologus derme, auricular cartilage and […]

PURPOSE: Measure of efficacy and the security of intraoperative of mitomycin C (MMC) in the pterygium surgery. METHODS: Realized prospective analysis of 102 patients (204 eyes) divided in two groups submitted intraoperative MMC 0.02 % for 2 minutes or saline solution 0.9%. The patients were available in 1º, 7 º, 21º, 30º, 60º and 90º days of postoperative. RESULTS: The pterygium was more prevalence in females (58,33%). The age various 33 to 69 years. The recidive (9) was in the […]

PURPOSE: To evaluate the prevalence and characteristics of pterygium in small communities along the Solimões and Japurá rivers, State of Amazonas, Brazil. Design: cross-sectional study. METHODS: This study was carried out on populations of the Brazilian Amazon rainforest. Data were collected by two separate ophthalmologists in three expeditions, covering 55 local communities. A total number of 1295 patients were examined, of which 659 were over 18 years old. The patients diagnosed with pterygium answered a questionnaire addressing gender, age and […]
