VEP versus subjective perimetry in evaluating thyrotoxic neuropathy

ABSTRACT

Pattern VEP record have been recorded for a group of patients with thyrotoxicosis whose central field and peripheral field records were analysed according to standard parameters of VEP for each record. These records were also compared to subjective perimetry results done for the patients using the Goldmann hemispherical perimeter. Results reflected definite changes in central field and peripheral field records and suggest that VEP is a simple objective method for the diagnosis of the preclinical states of thyrotoxicosis patients and for assessing thyroid optic neuropathy
