Computerized tomographic scan findings in facial fractures associated with blindness.
A retrospective study of 379 consecutive patients who underwent operative repair of facial fractures at the West Virginia University Medical Center found that blindness developed in at least one eye in 21 of the patients studied, and there was no previous report of an optic canal fracture as diagnosed by computerized tomography in the literature.

Electrophysiological discrimination between retinal and optic nerve disorders.
The amplitude of both positive and negative components fall with increasing severity of the disease thus showing that the abnormally long delau in VEP found in some cases is due to retinal disease rather than optic nerve disease. Expand

Analysis of the data obtained with 1 Hz and 10 Hz stimulation suggests that the components of the VEP related to visual acuity occur within the first 60-100 msec of the response, corresponding to the primary evoked response of Chiganek. Expand
The pattern electroretinogram in glaucoma and ocular hypertension.
Criteria have been devised which enable PERG measurements to distinguish all established glaucomatous eyes from all normal controls; these criteria demonstrate abnormalities in some OHT eyes, particularly those at high risk. Expand
Visually evoked potentials and electroretinography in neurologic evaluation.
Electrophysiologic testing of the visual system requires primarily the ERG and the VEP, which is based on electrical information recorded from the visual cortex in response to stimulation of the retina, and the integrity of the entire visual pathway can be tested. Expand

Comparison of preoperative 10-Hz visual evoked potentials to contrast sensitivity and visual acuity after cataract extraction
Cataract patients whose surgical outcomes were in question were referred for testing by visual evoked potentials, elicited through closed eyelids by a luminance stimulus (flash) that appeared 10Expand
10-Hz flash visual evoked potentials predict post-cataract extraction visual acuity
Cataract patients suspected of having disease which might interfere with good postoperative visual function were referred for evaluation. Monocular steady-state luminance visual evoked potentialsExpand
