However, his visual evoked potential was found to be abnormal upon binocular and monocular testing due to a low amplitude response. [annalsofian.org]

His abnormal visual evoked potentials may be suggestive of ocular involvement, although it was not appreciated on history or physical examination. [annalsofian.org]

This may play a major role in the observed oculomotor symptoms and may also be the cause of the abnormal visual evoked potentials seen in our patient. [annalsofian.org]

Cortical Blindness

Visual evoked potentials recorded during blindness were abnormal in 15 of 19 patients, but did not correlate with the severity of visual loss or with outcome. [ncbi.nlm.nih.gov]

Computed Tomography Scans showed no abnormalities. Visual evoked potential (VEP) was not performed as it was unavailable. [ncbi.nlm.nih.gov]
