Nerve Fiber Layer Infarcts in Thiamine Deficiency

Journal of Neuro-Ophthalmology, 2015
Thiamine deficiency classically manifests as the triad of Wernicke encephalopathy: acute confusional state, ataxic gait, and ocular motor dysfunction. However, most patients do no present with this classic triad. Optic neuropathy in thiamine deficiency is a rare manifestation and is usually associated with fundus appearances of optic disc swelling or ...

Retinal Nerve Fiber Layer Measured by Heidelberg Retina Tomograph and Nerve Fiber Analyzer

European Journal of Ophthalmology, 2005
Purpose To compare retinal nerve fiber layer (RNFL) thickness measured by Heidelberg retina tomograph (HRT) and nerve fiber analyzer (GDx). Methods Twenty eyes of 20 consecutive healthy subjects were recruited for this study. Each subject had a normal visual field and a normal optic nerve head, which was assessed by slit-lamp biomicroscopy using a 90 ...

Birefringence of the primate retinal nerve fiber layer

Experimental Eye Research, 2005
The purpose of this study was to measure the peripapillary retinal nerve fiber layer (RNFL) thickness, phase retardation (PR), and depth-resolved birefringence (Deltan) of the normal primate eye using Enhanced Polarization-Sensitivity Optical Coherence Tomography (EPS-OCT). Both eyes of two rhesus monkeys were imaged with EPS-OCT.

Optic nerve and retinal nerve fiber layer analyzers in glaucoma

Current Opinion in Ophthalmology, 2002
There is mounting evidence that retinal nerve fiber layer (RNFL) loss precedes detectable visual field loss in early glaucomatous optic neuropathy. However, examination and photography of the RNFL is a difficult technique in many patients, particularly older individuals, and eyes with small pupils and media opacities.

The Retinal Nerve Fiber Layer in Normal Eyes

Ophthalmology, 1989
The retinal nerve fiber layer is different in normal and glaucomatous eyes. The authors used red-free photographs to examine the retinal nerve fiber layer in 234 normal eyes. The retinal nerve fiber layer was most visible in the inferior temporal arcade, followed by the superior temporal arcade, then by the temporal macular area, and finally the nasal ...

Cross-Polarization Photography of the Nerve Fiber Layer

Archives of Ophthalmology, 1984
Cross-polarized photography was used to enhance the visibility of the arcuate bundles of the retinal nerve fiber layer ( NFL ). A fundus camera (Zeiss) was modified to accept a linear polarizing filter in front of the flash and another polarizing filter in front of the film plane. The azimuths of the two filters were kept at right angles to one another.

Retinal nerve fiber layer in multiple sclerosis

Acta Ophthalmologica, 1990
Abstract. To evaluate the usefulness of the retinal nerve fiber layer (RNFL) appearance in estimation of optic nerve damage in MS, we examined 20 patients with definite MS and 20 normal control patients. Photographs of the RNFL in 80 eyes were classified as normal or abnormal by two examiners working independently.
