“…PVEP latency delays secondary to retinal dysfunction have been reported [5,[8][9][10] and the PERG findings in the one patient in this study with a delayed PVEP are then of particular interest. It has recently been demonstrated [ 10] that the PERG can usually distinguish between PVEP delays due to optic nerve disease and those arising more distally.…”

This study reports the pattern visual evoked potential (PVEP) findings in 10 patients with idiopathic hypothyroidism. Eight of these patients also had pattern electroretinography (PERG) performed and six were additionally seen after treatment with thyroxine. Only one patient had definitely abnormal PVEPs at the time of initial recording. PERGs at this time were of abnormal latency and subnormal amplitude. Following treatment with thyroxine the patient became euthyroid. Repeat electrodiagnostic testing now showed both PERGs and PVEPs within the normal range, having markedly improved in both latency and amplitude. This suggests that the PVEP delay was probably secondary to reversible central retinal dysfunction.

“…Monocular PVEP examination was performed with a high contrast (89%) high luminance (mean 400cd/m 2) moving mirror checkerboard stimulus according to our standard techniques [4,5]. Occipital electrodes were 2 cm anterior and 2cm lateral to the inion recording in relation to ipsilateral sylvian electrodes.…”
