Pattern Evoked Potential Latency and Contrast Sensitivity in Glaucoma and Ocular Hypertension P. latency for the glaucomatous eyes was significantly longer than the P. latency for the normals and ocular hypertensives. Further, there was no significant difference in mean P. latency between the normals and ocular hypertensives.

Visual Evoked Potential (VEP) Methods of Detecting Misrouted Optic ProjectionsEPs to disappearance or pattern reversal stimuli. Acuity and nystagmus seem to be the two variables most indicative of poor pattern reversal responses. Appearance/disappearance (onset/offset) pattern stimuli are more versatile for detection of abnormalities in the visual system than pattern reversal stimuli.

Early Wavelets in the VECPimplicit times of 23, 30, and 38 mS. It is concluded that the VECP wavelets are not volume conducted from the retina, and probably represent initial arrival of visual information at the cortex or subcortical activity.

Comparison of Visual Field Examination and Visual Evoked Cortical Potentials in Multiple Sclerosis Pons of the visual pathways in MS patients. This study shows that in these cases careful visual field examination may be at least as useful as the assessment of VEP. From our 29 patients (58 eyes) a visual field defect was found in 46 eyes, while a VEP latency delay was found in 32 eyes.

Ethambutol Mainly Affects the Function of Red/Green Opponent Neuronsphysical and electrophysiological methods clearly indicate that signals of all three types of spectrally different cones are present in the visual cortex; however, the signs of color-opponent interactions between the individual cone mechanisms are lacking. Therefore it becomes evident that ETHAMBUTO

Early Components of the Visual Evoked Potential in ManA visual evoked potential of mean latency P20-N26-P34 has been recorded in 93% of normal subjects maximally from an electrode position slightly posterior to the Rolandic/Sylvian fissure and around the upper mastoid process..This potential is topographically separated from the lid ERG and the occipit
