O descolamento da membrana de Descemet pode ser uma complicação grave após a cirurgia de catarata, resultando em edema de córnea e redução da acuidade visual. Este relato descreve um caso raro de descolamento da membrana de Descemet seis meses após cirurgia de catarata com facoemulsificação sem intercorrências, documentado com tomografia de coerência óptica do segmento anterior (OCT; RTVue, Optovue). Foram realizadas descemetopexia pneumática e sutura corneana, com resolução do descolamento e recuperação visual. Este relato procura alertar os médicos […]

The detachment of Descemet’s membrane can be a serious complication following cataract surgery, leading to severe corneal edema and reduced visual acuity. This report describes an unusual case of Descemet’s membrane detachment 6 months after successful phacoemulsification, documented by anterior segment optic coherence tomography (OCT; RTVue, Optovue). The eye was treated successfully with pneumatic descemetopexy and transcorneal suturing, with reattachment of Descemet’s membrane. This report should alert physicians that delayed corneal edema can be related to late-onset Descemet’s membrane detachment, […]

A case of unilateral visual loss and right eye presenting intense pre-orbital bleeding was described in patient 80 years old, after upper and lower bilateral blepharoplasty surgery. Ophthalmologic examination showed clinical profile of posterior ischemic optic neuropath with superior hemianopsia and magnetic resonance imaging (MRI) of normal orbit. Comments are made on possible mechanism involved in the process as well as analysis on the evolution of the retinal nerve layer by optical coherence tomography.

PURPOSE: To evaluate the retinal nerve fiber layer (RNFL) in sickle cell disease with optical coherence tomography (OCT). METHODS:The present study selected patients with sickle cell disease (SS) from the Federal University of Goias, and normalvolunteers, controlled by age and sex. Inclusion criteria for both groups were: visual acuity e” 20/30 without correction, intraocular pressure d” 21mmHg and a reliable and normal 24-2 Sita Standard visual field and optic disc. Thereafter, all subjects were submitted to OCT, Fast RNFL strategy, […]

OBJECTIVE: The objective of this work is to evaluate by means of the OCT Stratus the relation of the macular thickness with the thickness of nervous fiber layers. METHODS: In this work 106 eyes of the service of ophthalmology of the College of Medicine of the ABC had been analyzed. The study included 55 eyes that inside presented values of CFNR or above of the normal values in all the four quadrants and 51 eyes presenting values in only one […]

OBJECTIVE: To compare the thickness of the retinal nerve fiber layer (RNFL)and the macular thickness of the amblyopic eye with those of the non-amblyopic eye in patients with unilateral amblyopia using optical coherence tomography (OCT). METHODS: OCT was performed for13 patients with unilateral amblyopia who had no neurologic disease. Nine male andfour female patients, whose ages ranged from 23 to 63 years, were enrolled in the study. The RNFL thickness average analysis program was used to evaluate mean superior, inferior, […]

Optical coherence tomography was progressively incorporated to the contemporary diagnostic arsenal in Ophthalmology, playing a crucial role in the diagnosis and management of eye diseases, particularly in the specialty of retina and vitreous. The commercial availability of the new generation of devices, coined “spectral” optical coherence tomography, which is based in a distinct physical concept that permits high-speed image acquisition, launched a new era for this investigative ancillary tool. In addition, the recent combination of this new technology with a […]

OBJETIVO: Relatar alterações na camada de fibras nervosas retiniana (CFNR) com o uso da tomografia por coerência óptica (TCO) Stratus em pacientes com lesões do trato óptico. MÉTODOS: Dois pacientes com hemianopsia homônima de longa duração decorrente de lesões do trato óptico foram submetidos a avaliação neuroftalmológica completa e tomografia por coerência óptica Stratus. RESULTADOS: Ambos pacientes demonstraram redução difusa da CFNR nos dois olhos. Nos olhos com a hemianopsia temoporal, a perda da CFNR foi difusa mas com predomínio […]
