The primary congenital entropion of the superior eyelid is more infrequent than the one of the inferior eyelid. The premature diagnosis of this deformity in newborns, although difficult, is very necessary because implies an immediate surgical correction as it is a condition that does not recover spontaneously even leading to corneal ulceration with disastrous consequences for the vision. Many surgical techniques have been described to correct this malformation. The analysis and confrontation of the pre, per and postoperative data of […]

Diabetic macular edema must be assessed as early as possible, to avoid significant vision loss. To achieve this goal, there are many specific diagnostic tests that can be performed. The authors review the most common methods in diagnosing diabetic retinopathy.

PURPOSE: To compare intraocular pressure (IOP) readings of Goldmann applanation tonometry (GAT) and dynamic contour tonometry (DCT), and to correlate central corneal thickness (CCT) with these readings. METHODS: This transversal study included patients in two groups: open-angle glaucoma (OAG) and normal eyes (NE). IOP measurements were obtained in all patients using GAT and DCT. The same examiner made all GAT measurements. Another examiner, who was masked to the GAT readings, made DCT measurements. CCT was determined by ultrasound pachimetry. RESULTS: […]

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: […]

PURPOSE: To evaluate b-wave of the electroretinogram of the burrowing owl (Athene cunicularia), differentiating the retinal electric reply in photopic and scotopic environment. METHODS: Transversal observational study was carried through, with the register of the full field electroretinogram of fourteen eyes; seven were stimulated in photopic environment and seven in scotopic environment using with white light according to the ISCEV protocol. RESULTS: The electrical responses of the retina of the species studied showed no statistically significant difference for the applied […]

OBJECTIVE: To study the frequency of retinopathy of prematurity (ROP) in any stage and its threshold form in premature infants, either treated or non-treated with exogenous surfactant to neonatal respiratory distress syndrome, and evaluate the response of eyes with threshold retinopathy to ablation treatment. METHODS: One hundred and sixty eight premature infants who weighed 1500 grams or less and/or who had a gestational age of 32 weeks or less, were screened for ROP by ophthalmoscopy. We compared findings in 40 […]

PURPOSE: Diabetic dermopathy is the most frequent cutaneous marker of diabetes mellitus. Although diabetic dermopathy and diabetic retinopathy are both considered as manifestations of diabetic microangiopathy, there are only few reports in the literature regarding their possible association. The purpose of this study was to investigate the association between diabetic dermopathy and diabetic retinopathy and to determine the prevalence and the associated risk factors for diabetic retinopathy in type 2 diabetes patients from the Outpatient Diabetic Clinic of the Faculty […]
