1. New perspectives on macular hole surgery at three years of follow-up
RESUMO Objetivo: Determinar, após 3 anos de seguimento, as taxas de sucesso funcional e anatômico e a segurança da cirurgia combinada sem sutura, incluindo remoção da base vítrea e da membrana limitante interna após coloração com azul brilhante (0,5 mg/ml) para o manejo de buracos maculares idiopáticos. Métodos: Quarenta e seis olhos de 46 pacie

2. Ocular abnormalities in morbid obesity
RESUMO Objetivo: A obesidade está associada a doenças oulares, mas as mudanças estruturais subjacentes e os mecanismos patogênicos não foram examinados detalhadamente. Aqui avaliamos os efeitos da obesidade mórbida nos índices morfométricos da doença ocular. Métodos: Voluntários obesos mórbidos (n=101, índice de massa corporal ³40) e indivíd

3. Biomarcadores e desfechos substitutos na neuropatia óptica glaucomatosa: novos desenvolvimentos e uma revisão
RESUMO O glaucoma compreende um grupo de neuropatias ópticas progressivas que tem em comum a degeneração lenta e progressiva das células ganglionares e seus axônios, resultando em aparência única do disco óptico e, simultaneamente, um padrão correspondente de perda visual. Biomarcadores são características medidas objetivamente e avaliadas como in

4. Imaging studies for diagnosing Graves' orbitopathy and dysthyroid optic neuropathy
Although the diagnosis of Graves' orbitopathy is primarily made clinically based on laboratory tests indicative of thyroid dysfunction and autoimmunity, imaging studies, such as computed tomography, magnetic resonance imaging, ultrasound and color Doppler imaging, play an important role both in the diagnosis and follow-up after clinical or surgical treatment

5. Rastreamento em vídeo das características da pupila / Video tracking of pupil features
The study of the pupil s movements has signicant clinical interest because it acts as an objective indicator of retinal sensitivity to light and, consequently, of the optic nerve. Its permanent oscillation is the result of balance between opposing ows of the sympathetic and parasympathetic nervous system. The pupil s state of an individual allows the diagnos

6. Ocular problems in brazilian patients with AIDS before and in highly active antiretroviral therapy (HAART) era
This study determined the total frequency of patients with AIDS and ophthalmologic problems before and after the introduction of combined highly active antiretroviral therapy (HAART), regardless of the use of this treatment; it also determined the frequency of external ocular diseases, intraocular infections and inflammations, and problems of the anterior po

7. "Análise comparativa das medidas de espessura da camada de fibras nervosas da retina de pacientes com atrofia em banda do nervo óptico e de indivíduos normais através da tomografia de coerência óptica e da polarimetria a laser" / A comparative analysis of the retinal nerve fiber layer thickness measurements in patients with band atrophy of the optic nerve and in normal controls using optical coherence tomography and scanning laser polarimetry
Most diseases that affect the optic pathways present clinically with loss of one or more visual functions.When optic pathway injuries involve the anterior visual pathways they may cause loss of the retinal nerve fiber layer (RNFL) and "band atrophy" (BA). The purpose of this study was therefore to compare the ability of the optical coherence tomography (OCT)

8. Comparison of Snellen acuity, VER acuity, and Arden grating scores in macular and optic nerve diseases.
Patients with various macular and optic nerve abnormalities underwent Snellen acuity, transient VER acuity, and Arden grating testing. Snellen acuity was the coarsest of the 3 evaluations, generally falling after Arden scores and VER acuity had already undergone significant degradation. The Arden gratings appeared to be the most sensitive of the 3 tests, equ

9. Optic nerve diameters and perimetric thresholds in idiopathic intracranial hypertension.
AIMS/BACKGROUND--Idiopathic intracranial hypertension (IIH) is a central nervous disorder characterised by abnormally increased cerebrospinal fluid (CSF) pressure leading to optic nerve compression. An indirect estimate of increased CSF pressure can be obtained by the ultrasonographic determination of optic nerve sheaths diameters. Computerised static perime

11. Nerve fibre layer loss in diseases of the outer retinal layer.
We present examples of nerve fibre layer changes in diseases thought to affect primarily the outer retinal layers. These disease processes include cone-rod dystrophies, rod-cone dystrophies, juvenile macular degeneration (Stargardt's disease) and fundus flavimaculatis, vitelliform macular dystrophy, and Leber's congenital amaurosis. All were associated with

12. Clinical features, molecular genetics, and pathophysiology of dominant optic atrophy.
Inherited optic neuropathies are a significant cause of childhood and adult blindness and dominant optic atrophy (DOA) is the most common form of autosomally inherited (non-glaucomatous) optic neuropathy. Patients with DOA present with an insidious onset of bilateral visual loss and they characteristically have temporal optic nerve pallor, centrocaecal visua
