Analysis of Peripapillary Retinal Nerve Fiber
Distribution in Normal Young Adults.
Objective: To compare mean retinal nerve fiber
layer (RNFL) thickness in patients having pseudo exfoliation (PXF) with normal age matched controls using spectral domain optical coherence tomography (SD-OCT).
Objectives: The presence of retinal nerve fiber
layer (RNFL) split bundles was recently described in normal eyes scanned using scanning laser polarimetry and by histologic studies.
The correlation between retinal nerve fiber
thickness and cognition was observed in the large cohort at baseline, Fang Sarah Ko, MD, said during a press briefing at the Alzheimer's Association International Conference 2016.
Corneal nerve fiber
assessment has great potential as a tool to diagnose and monitor peripheral neuropathy induced by HIV, say scientists at the Johns Hopkins University School of Medicine.
Frequencies and percentages of the contour of neuroretinal rim, appearance of nerve fiber
layer, presence of optic disc hemorrhages, colour of optic nerve head was noted.
To increase the speed at which these signals travel, each nerve fiber
is encased by a sheath formed from a fatty substance, called myelin.
The study is measuring the status of the optic nerve using vision tests and OCT (optical coherence tomography, a quick, non-invasive eye test that can show nerve fiber
damage and health).
This stimulation elicits action potential discharges that propagate along the nerve fiber
, eventually reaching auditory centers in the brainstem.
The results revealed that subepithelial nerve fiber
bundles of the anterior, medium and posterior regions of tongue were arise from deep muscular layer of tongue.
Diabetic neuropathy was associated with progressive, significant reductions in corneal sensitivity (as measured by non-contact corneal aesthesiometry), nerve fiber
density, nerve branch density, and nerve fiber
The team used the current perception threshold test to examine nerve fiber
populations in the workers' shoulders, arms, wrists, and hands.
