Report of four cases of presumed ocular tuberculosis, with involvement of the posterior segment in tree cases. In the first and second case, report anterior involvement of the eye and antecedent of tuberculosis, in a systemic case and the other ocular. In the third case, patient presents coriorretiniana lesion in the left eye. In the fourth case, report lesion serpiginosa-like.The patients under-went the treatment for tuberculosis. The ocular lesions of the tuberculosis are polymorphic and we must be aware of […]

Purtscher-like retinopathy is acute loss of vision associated image of the multiple areas of retinal whitening and hemorrhage in the posterior pole of both eyes. The exact mechanism of injury remains unclear, current evidence suggests that it is embolic in nature. In a variety of conditions are been described including acute pancreatitis, fat embolism syndrome, renal failure, childbirth, and connective tissue disorders. Will are related three cases of the acute pancreatitis which was confirmed by complementary laboratory studies and clinical […]

Assessment of the vitreoretinal interface has been greatly aided by the development of optical coherence tomography, in 1995. This imaging technology has allowed us to study involutional and disease processes that were previously unrecognizable by biomicroscopy and ultrasonography alone.This article will review these studies and illustrate the usefulness of optical coherence tomography in the evaluation of the vitreoretinal interface.

OBJECTIVE: To present a model of assessment of the satisfaction level of the attendants in a short-duration course, considering the financial costs and the acquired knowledge. METHODS: By means of the presentation of questionnaires, a transversal study on a promptly accessible sample of ophthalmologists (n=29) who attended the “II Course on Transfer of Skills on Adaptation to Contact Lenses” at Sirio-Libanês Hospital, was carried out. RESULTS: The sample was formed by 29 individuals, being 58,6% men and 37,9% women (one […]

PURPOSE: To explorethe effect of the thalamosinusotomy ab interno, which is an experimental surgical procedure similar to sclerothalamotomy ab interno, on aqueous humor drainage. METHODS: Enucleated porcine eyes were perfused with Krebs-Ringer’s physiologic solution and trypan blue, in vitro, under different constant pressures after the experimental procedure.The outflow facility and the stained/unstained tissue were measured. RESULTS: The outflow facility and the area under the curve (outflow) increased with the increasing number of thalamosinusotomy incisions (0 to 4). Thalamosinusotomy eyes showed […]

OBJETIVO: Avaliar o efeito da thalamosinusotomia ab interno, que é um procedimento cirúrgico experimental similar a esclerotalamotomia ab interno, na drenagem do humor aquoso. MÉTODOS: Olhos de porco enucleados foram perfundidos com solução fisiológica de Krebs-Ringer e azul de tripan, sob diferentes pressões constantes de perfusão, após o procedimento cirúrgico experimental. A facilidade de drenagem e os tecidos corados/não corados foram medidos. RESULTADOS: A facilidade de drenagem e a área sob a curva (fluxo) aumentaram com o aumento do número […]

PURPOSE: To evaluate intraocular pressure variation due to postural changing of supine to sitting position and, to correlate this variation with visual field defects in primary open angle and normal tension glaucoma patients, as well as normal eyes. METHODS: Thirty-two eyes of 32 POAG patients, 30 eyes of 30 NTG patients and 20 eyes of 20 normal patients were evaluated in the study. Intraocular pressure was measured at 6 o’clock in supine position and 5 minutes after in sitting position […]
