Retinal Nerve Fiber Layer Measured by Heidelberg Retina Tomograph and Nerve Fiber Analyzer
European Journal of Ophthalmology, 2005Purpose 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.

Retinal Nerve Fiber Layer Photography in Glaucoma
Ophthalmology, 1985Retinal nerve fiber layer (RNFL) photographs can be used for detection of early glaucomatous damage and in the follow-up of patients with established glaucoma. Enlarged black-and-white paper-prints taken with a wide-angle fundus camera as well as stereophotographs of the peripapillary retina have proven quite useful.

Computerized enhancement of retinal nerve fiber layer
Acta Ophthalmologica, 1986Abstract We investigated a number of image processing techniques for enhancing the retinal nerve fiber layer (NFL) in fundus photographs taken with red‐free light. Wedge‐type defects within the NFL were enhanced best by contrast enhancement algorithms such as histogram modification and extremum sharpening.

PHOTOGRAPHY OF THE NERVE FIBER LAYER IN RETINAL DISTURBANCES
Acta Ophthalmologica, 1977The diagnostic value of nerve fiber layer photography is assessed. The series comprised 39 patients with various neuro‐ophthalmological diseases. Photography of the nerve fibers in the retina is time consuming and requires skill on the part of the photographer.

Nerve Fiber Layer Infarcts in Thiamine Deficiency
Journal of Neuro-Ophthalmology, 2015Thiamine 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 in multiple sclerosis
Acta Ophthalmologica, 1990Abstract. 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.

Cross-Polarization Photography of the Nerve Fiber Layer
Archives of Ophthalmology, 1984Cross-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.

Optic nerve and retinal nerve fiber layer analyzers in glaucoma
Current Opinion in Ophthalmology, 2002There 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, 1989The 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 ...

Birefringence of the primate retinal nerve fiber layer
Experimental Eye Research, 2005The 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.
