Visual evoked potential (VEP) testing is used frequently and an important ophthalmologic physiological test to examine visual functions objectively. The VEP a complicated waveform consisting of negative named N75 N135, positive P100. Delayed P100 latency greatly attenuated amplitude on are known characteristics for diagnosing optic nerve disease. Acupuncture has been treat wide clinical symptoms with minimal side effects. confirmation the efficacy acupuncture generally relies subjective symptoms. There not much scientific evidence supporting treatments eye diseases up today. However, can evaluate objectively numerically treatment by acupuncture. We analyzed 19 healthy subjects (38 eyes). latencies in group less than 101.7 msec (total average) before stimulations were different those after (98.2 ± 3.0 msec, 98.2 4.0 respectively, p = 0.88, n 17), but longer or equal statistically (104.6 2.8 101.9 3.7 0.006, 21). These results show that stimulation contributes pattern reversal (PR)-VEP some who have delayed latencies, this electrophysiological method valuable technique monitoring effectiveness therapy improvements functions. purpose study effects using PR-VEP normal subjects.
