Thickness of the Retinal Nerve Fiber Layer in Primate Eyes

Archives of Ophthalmology, 1980
Thickness of the retinal nerve fiber layer is studied in the eyes of three primate species. Measurements are made at various points throughout the fundus, including the peripapillary, arcuate, macular (area centralis), equatorial, and peripheral parts of the retina.

Retinal Nerve Fiber Layer Thickness in Optic Tract Syndrome

Japanese Journal of Ophthalmology, 2005
Optic tract syndrome (OTS) is characterized by incongruous homonymous hemianopia and a perpendicular pattern of bilateral optic atrophy due to the optic tract lesion. However, loss of retinal nerve fiber layer thickness (RNFLT) associated with OTS has not been quantitatively assessed.A 20-year-old woman with blunt head trauma showed normal visual ...

Reduction in retinal nerve fiber layer thickness in migraine patients

Neurological Sciences, 2012
Migraine is a common disorder and its pathogenesis remains still unclear. Several hypotheses about the mechanisms involved in the pathogenesis of migraine have been proposed, but the issue is still far from being fully clarified. Neurovascular system remains one of the most important mechanisms involved in the pathogenesis of migraine and it could be ...

Peripapillary retinal nerve fiber layer thickness in preeclampsia and eclampsia

International Ophthalmology, 2017
To evaluate peripapillary retinal nerve fiber layer (RNFL) thickness during and after pregnancy in pregnant women with preeclampsia or eclampsia and compare it with normotensive pregnant women as controls.In a prospective comparative case-control study 35 women (70 eyes) with mild to moderate preeclampsia, 70 women (140 eyes) with severe preeclampsia ...

Retinal nerve fiber layer thickness in Vigabatrin‐exposed patients

Annals of Neurology, 2011
Abstract Objective: Vigabatrin‐associated visual field loss (VAVFL) occurs in 25 to 50% of exposed patients and is routinely monitored using perimetry, which has inherent limitations. Using optical coherence tomography (OCT), retinal nerve fiber layer (RNFL) thinning has been described in a ...

Measurement of the retinal nerve fiber layer thickness in clinical routine

Current Opinion in Ophthalmology, 1998
The possibilities and limitations of methods for indirect and direct nerve fiber layer thickness (NFLT) measurements, and a summary of our own clinical studies using Optic Nerve Head Analyzer (Rodenstock, Munich, Germany) (ONHA), Laser Tomographic Scanner (Heidelberg Engineering, Heidelberg, Germany) (LTS), Heidelberg Retinal Tomograph (Heidelberg ...

The Relation Between the Reflectance and Thickness of the Retinal Nerve Fiber Layer

Journal of Glaucoma, 1995
This study examined quantitatively the commonly held assumption that the reflectance of the retinal nerve fiber layer is proportional to its thickness.The reflectance of the retinal nerve fiber layer of an in vitro vertebrate cyecup preparation was measured with an imaging microreflectometer, an instrument that provided quantitative images of a small ...

Retinal nerve fiber layer thickness in benign multiple sclerosis

Multiple Sclerosis Journal, 2013
Background/objective: Retinal nerve fiber layer (RNFL) thickness has been linked to brain atrophy in multiple sclerosis (MS). However, little is known about retinal atrophy in ‘benign’ MS.

Retinal Nerve Fiber Layer Thickness Alteration in Apneic Children

Optometry and Vision Science, 2016
ABSTRACT Purpose We examined retinal nerve fiber layer (RNFL) thickness alterations in children with chronic upper airway obstructions (UAOs) and obstructive sleep apnea syndrome (OSAS). We also investigated whether it was affected by an adenotonsillectomy operation.

Retinal Nerve Fiber Layer Thickness in Normal Human Eyes

Ophthalmology, 1996
To measure the histologic thickness of the retinal nerve fiber layer (RNFL) in normal human eyes.Human eyes were obtained at autopsy within 6 hours postmortem. The retina was dissected into four quadrants and serially sectioned in historesin. The RNFL thickness was measured histologically in all four quadrants at the disc margin and at regular ...
