Visual evoked potentials as an aid in the diagnosis and treatment of temporal arteritis

A patient who presented with temporal arteritis was followed using pattern visual evoked potentials (VEPs). Prior to treatment, both amplitudes and wave latencies of the VEP were abnormal. Following a two-week course of corticosteroids, both the visual acuity and VEPs returned to normal. It is suggested by this patient, that VEPs may be useful in the diagnosis and management of patients with temporal arteritis.
