In the scientific environment there is no information in store. Once a study is over, the strongest desire of researchers is promote by means of publication of scientific articles their results worldwide, in order to consolidate their position as reference in the subject. Among the most organized research teams, which in Brazil typically belong to pos-graduation programs, there are many stimuli for this mentality to prevail, like governamental funds, bonuses, advance in career, besides maintenance of the pós-graduation program accreditation […]

OBJECTIVE: Compare PRK and Epi-LASIK techniques regarding postoperative visual recovery and symptoms. METHODS: Interventional case series study including 38 eyes of 19 patients with myopia up to 5DE and astigmatism up to 1DC. Study included patients with similar refractive errors to be submitted to PRK in one eye and Epi-LASIK in the fellow eye at the same time. Follow-up was 1 year and included refractive error analysis and postoperative discomfort. RESULTS: During the first 12 hours after surgery, 79% (P=0,0003) […]

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.

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 […]

OBJECTIVE:This study aims to identify and critically examine the personal and social autonomy of visually impaired people (blindness) after undergoing rehabilitation services in a single specialized institution. METHODS: The method used in the study possessed qualitative approach, by organizing interviews and questionnaires to collect data. Study subjects are visually impaired people (blindness), who went through rehab, and their family members who accompanied the process.. The study involved the six people with visual impairments, graduates of the Unit for Rehabilitation of […]

The intrastromal corneal ring implant surgery is becoming a surgical procedure in the treatment of keratoconus additive in order to minimize and delay the complications inherent to the pathology. Its action consists in the remodeling cornea, flattening and regulating the central corneal surface. Nowadays with the advent of new technologies, there is an important contribution in the diagnosis of keratoconus, with not only diagnosis but also more effective with better monitoring and prognosis of patients with this disorder ectatic. In […]

The authors report a case of a patient who presented bilateral branch retinal artery occlusion without any meaningful systemic underlying conditions.

Os autores descrevem paciente do sexo masculino, 48 anos, com diminuição visual bilateral há 15 dias por membrana neovascular sub-retiniana secundária a estrias angióides. A acuidade visual com melhor correção no olho direito era 20/80 e no olho esquerdo de conta dedos a 2 metros. Submetido à injeção intravítrea de Ranibizumabe (Lucentis) no olho com pior acuidade visual. Após 15 dias do tratamento, referiu melhora acentuada da visão no olho contralateral com visão de 20/25.
