Abstract:
The light emitting diode (LED) stimulator was used to record PVEP from 59 eyes (38 patients) with optic neuropathy and 46 eyes (23 patients) with cataract. The amplitude and the latency of P100 in LED PVEP were comparable to those in TV PVEP with insignificant differences (P > 0.05), suggesting that LED PVEP may be used in the evaluation of visual function and prognosis of patients with optic neuropathy or cataract.
