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.

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 ...

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.

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.

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.

Retinal Nerve Fiber Layer Thickness in Various Retinal Diseases
Optometry and Vision Science, 2018Supplemental digital content is available in the text. SIGNIFICANCE Peripapillary retinal nerve fiber layer (RNFL) thickness measurements may be influenced by the range and severity of lesions that are observed distinctively in each ...

Preservation of Nerve Fiber Layer by Retinal Vessels in Glaucoma
Ophthalmology, 1992The authors evaluated the correlation between various parameters and the local preservation of the retinal nerve fiber layer in 156 glaucomatous eyes. A vessel-associated preservation of the nerve fiber layer was observed in 45 of the 156 glaucomatous eyes.

Retinal Nerve Fiber Layer Thickness in Children With ADHD
Journal of Attention Disorders, 2016Objectives: The current study aims to compare retinal nerve fiber layer (RNFL) thickness, macular thickness, and macular volume between children with ADHD and a control group. Method: The study group included children with ADHD and the control group consisted of age- and gender-matched participants without any psychiatric disorder. In all participants,

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.
