OBJECTIVE:To determine the refractive profile of presbyopic people in the western brazilian Amazon, establishing as the pilot cities Manaus and other nine of sixty-one cities in the state of Amazonas. METHODS: Retrospective analysis of medical records of 8.225 patients. People who were over the age of 40 in 10 cities in the state of Amazonas (Manaus and 09 municipalities in the hinterland) were examined from september/2008 to december/2011. The data were classified by age, sex, economic activity (retired or not), […]

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): […]

PURPOSE: The present work aimed to present the development of a conjunctival mucosa system for the controlled delivery of cyclosporine A (CsA) in the treatment of keratoconjunctivitis sicca (KCS). METHODS: The conjunctival mucosa system was prepared in the form of films containing chitosan as the polymer and CsA as the drug (25%w/v). The films were applied to the conjunctival sac of one eye from normal rabbits (n=6), and the evaluation of lachrymal production was performed daily, before and after application, […]

OBJECTIVE: To evaluate the effects of diluted topic anesthetic proximetacaine on the symptoms and corneal re-epithelialization in postoperative photorefractive keratectomy (PRK). METHODS: A prospective, comparative and double-blind Study. Patients were divided into two groups: With (n=32) and Without (n=24) the use of Mitomycin C at 0.02% (indicated for eyes with 4 or more diopters). Each patient received two bottles of eye drops one had artificial tear carmellose sodium 0.5%, and other had the same along with 0.125% proximetacaine. The choice […]

PURPOSE: To correlate straylight levels, lens scattering, lens opacity and intraocular aberrometry in patients with nuclear cataract. METHODS: This is a prospective study. Thirty consecutive patients (30 eyes) were including. Ocular Straylight was evaluated using the C-Quant. Lens scattering was evaluated using Scheimpflug anterior segment tomography, using the new software PNS. Dilated slip lamp evaluation was performed and lens opacity was classified according to LOCS III scale. Total wavefront was measured by ray tracing (iTrace); intraocular aberrations were calculated by the […]

OBJECTIVE: To evaluate, retrospectively, in a long time interval, the results of transpupillary thermotherapy in selected cases of choroidal melanoma (CM). METHODS: All patients with melanoma treated with transpupillary thermotherapy as sole therapy or supplement were identified. Cases with less than 60 months follow-up, incomplete records or abandonment of monitoring were excluded. RESULTS: A total of 18 eyes, seven (38.9%) were included. Five (71,4%) patients were treated exclusively with transpupillary thermotherapy, in one (14,2%) eye criotherapy was used simultaneously, one […]

OBJECTIVE: To report a series of macular sparing rhegmatogenous retinal detachment (MSRRD) in patients treated with demarcation laser photocoagulation. METHODS: Retrospective, interventional, and noncomparative case series of 14 eyes in 12 patients with primary MSRRD. Eyes with previous chirurgical intervention were excluded from this study. All eyes received three or more rows of confluent demarcation laser photocoagulation at the margin of retinal detachment. Best corrected preoperative and postoperative visual acuity and progression of retinal detachment during the follow-up were recorded. […]

OBJECTIVE:To present our experience in endoscopic dacryocystorhinostomy, discussing the results with those found in the literature. METHODS: The material in this study consisted of sixteen surgeries performed in twelve patients followed between 2009 to 2011. We analyzed gender, age at surgery, etiology of dacryocystitis, clinical features, number of surgeries required to repair, follow-up. RESULTS: There was a predominance of females compared to males (5:1) aged between 8 and 71 years, mean35.2 years. With regard to etiology, eight were classified as […]
