Investigar os resultados da injeção intravítrea de Ranibizumab em pacientes com neovascularização de coróide da degeneração macular relacionada a idade, com atrofia geográfica extensa, pré-existente e revisão da literatura. MÉTODOS: Este é um artigo de revisão e também um estudo retrospectivo de 9 pacientes, 10 olhos com neovascularização de coróide da degeneração macular relacionada à idade, com atrofia geográfica extensa, pré-existente. Os pacientes incluídos apresentaram atrofia geográfica, envolvendo a fóvea ou adjacente, antes do desenvolvimento da neovascularização de coróide. A […]

PURPOSE: To determine the reproducibility of the peripapillary retinal nerve fiber layer thickness and optic nerve head parameters measured with the optical coherence tomography (SD-OCT) in normal eyes. METHODS: Thirty-four eyes of 34 healthy patients were included in the study. The Cirrus OCT optic disc cube 200×200 protocol was used to obtain three scans from each eye to evaluate the reproducibility. Intraclass correlation coefficient (ICC) was calculated for the measurements of retinal nerve fiber layer thickness and optic nerve head […]

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 […]

The acute retinal necrosis is a rare and devastating necrotizing retinitis, which can be caused by the herpes simplex virus type 1 or 2. It typically affects healthy patients of all ages. This study report a case of 18 year-old healthy male patient, with the the diagnosis of the acute retinal necrosis due to herpes simplex, and presents its clinical and ultrassonographic features. The acute retinal necrosis results in endofthalmitis because of lack of early diagnosis and therapy.

OBJECTIVE: To demonstrate the morpho-functional profile of the evaluation of patients with diabetic retinopathy without severe loss of visual acuity in a public hospital of reference in endocrinology, determining in this sample, the relation between the time of diabetes, age and visual acuity with the retinal thickness measured by the optical Coherence tomography (OCT) and fundus picture (FP). METHODS: Prospective, linear study was carried through, in transversal cut of 61 consecutive patients with diabetic retinopathy registered in the HRT, and […]

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 […]

The ultrasound is an important method in the evaluation of abnormalities of the posterior segment of the eye. PURPOSE: To compare the advantages and disadvantages of 10 and 20 MHz probe on B- scanning ultra-sonography in evaluation of vitreous and posterior pole diseases, providing recommendations for their use. METHODS: Patients from Hospital das Clinicas of the University of São Paulo (HC-FMUSP), attended between February 2006 and April 2007, were submitted to ultrasound exams using CINE-Scan® (Quantel Medical Inc) B-scan with […]
