A 34-year-old white man presented with a sudden unilateral recurrent visual loss. Fundus examination and fluorescein angiography revealed severe retinal vein occlusion. An antiphospholipid syndrome was discovered during etiological check up. A mutation of Leiden V factor was discovered and the patient started long term anticoagulation after the second occlusive event. However, secondary neovascular glaucoma has developed and despite treatment the affected eye had an important reduction of visual acuity. The purpose of this case report is to demonstrate that […]

Paciente do sexo masculino, 34 anos de idade, com baixa da acuidade visual recorrente. Fundoscopia e angiofluoresceinografia demonstraram oclusão venosa retiniana grave. Durante pesquisa etiológica diagnosticou-se a síndrome do anticorpo antifosfolípide com mutação do fator V Leiden. O paciente iniciou anticoagulação após o segundo evento oclusivo. Entretanto, evoluiu com quadro de glaucoma neovascular e, apesar do tratamento, o olho afetado teve importante redução da acuidade visual. O objetivo deste relato de caso é demonstrar que uma oclusão vascular retiniana pode […]

PURPOSE: Assess cost-effectiveness of glaucoma and/or ocular hypertension medical therapy using prostaglandin analogues in the state of Minas Gerais, Brazil. METHODS: This cross-sectional study evaluated the cost (average wholesale price) of different prostaglandin analogues (bimatoprost, latanoprost, travoprost) in relation to its effectiveness in reducing intra-ocular pressure. Monthly, annually and 5-year cost to achieve 1% and 20% of IOP reduction was calculated. Monthly, annually and 5-year cost to reduce 1 mmHg and 8 mmHg from baseline IOP was also calculated. RESULTS: […]

Topiramate is a kind of sulfamate-substituted monosaccharide of oral presentation to be used primarily as an anticonvulsant and it doesn’t have structural relation with any other antiepileptic agents. This wide range antiepileptic drug has been used in the management of migraine, depression and neuropathic pain. Since it was approved as an anticonvulsant, many reports related to ophthalmological adverse effects have been published. The pathological findings include secondary angle closure glaucoma, transitory myopia, ocular hyperemia, uveal effusions, with or without mydriasis.

PURPOSE: Could the central corneal thickness (CCT) change the intraocular pressure (IOP) measured by ICARE (IC) GOLDMANN APPLANATION TONOMETER (GAT) and PASCAL DYNAMIC COUNTOUR TONOMETER (PDCT). METHODS: Before using the anesthesia we have measured the IOP with IC tonometer. After that we have used topical anesthesia to obtain the CCT using an ultrasound pachymeter (Mentor Co.) and the IOP measured by PCDT followed by a drop of fluorescein to measured IOP with GAT. RESULTS: 138 eyes of 71 patients were […]

PURPOSE:To identify the most important variables interfering with the correct topical administration of antiglaucomatous drugs. METHODS: Forty glaucomatous patients under clinical treatment were interviewed and observed while applying antiglaucomatous drugs. The following variables were analyzed: sex; age; income; washing of the hands; number of drops; motor abnormalities; availability of another person to apply the drug; place of the globe reached; bottle-eye contact; previous instruction; positioning for application; development of a burning sensation, pain or irritation. Using the questionary, the variables […]

PURPOSE: To compare measurements of central corneal thickness obtained using a Haag-Streit optic pachymeter and a DGH 500 (Pachette Ttm ) ultrasonic pachymeter in normal patients. METHODS: An evaluation was made of 200 eyes of 100 patients using Optic (PO) and Ultrasonic (PU) pachymeters. Measurements were made in the area of the central cornea (ECC) respecting the 3.0 mm territory, in patients with normal corneas of hypermetropic, emetropic and myopic eyes. Patients with ocular diseases, ocular surgeries, and contact lens […]

The aim of this article is to make a review about glaucoma associated with penetrating keratoplasty, describing since its incidence and risk factors until the different options for treatment.
