Steady-state pattern electroretinogram and short-duration transient visual evoked potentials in glaucomatous and healthy eyes

Sensitivity and specificity of short-duration transient visual evoked potentials (SD-tVEP) in discriminating normal from glaucomatous eyes.

PURPOSE To evaluate the ability of the short-duration transient visual evoked potential (SD-tVEP) to discriminate between healthy eyes and eyes with early to advanced glaucomatous visual field loss. METHODS We tested 30 eyes of 30 healthy controls and 45 eyes of 35 glaucoma patients. Normal eyes had 20/30 or better visual acuity and normal 24-2 Swedish interactive thresholding algorithm (SITA...

simultaneous pattern visual evoked potential and pattern electroretinogram in strabismic and anisometropic amblyopia

Pattern reversal visual evoked potentials in eyes with macular holes and their fellow eyes.

PURPOSE To investigate whether the pattern reversal visual evoked potential can be useful in the diagnosis and management of macular hole patients. METHODS The pattern reversal visual evoked potential was measured in 66 patients with a macular hole and in 43 healthy control subjects. Check sizes of 34', 17' and 10' were applied. RESULTS Results showed that, for the check sizes of 34', 17' a...

Conscious Wireless Electroretinogram and Visual Evoked Potentials in Rats

The electroretinogram (ERG, retina) and visual evoked potential (VEP, brain) are widely used in vivo tools assaying the integrity of the visual pathway. Current recordings in preclinical models are conducted under anesthesia, which alters neural physiology and contaminates responses. We describe a conscious wireless ERG and VEP recording platform in rats. Using a novel surgical technique to chr...
