- Abstract
- This study was carried out to establish normal values and to compare the pattern reversal and light emitting diodes(LED) stimulating visual evoked potential(VEP) in 30 healthy volunteers (20 men and 10 women, age ranged from 24 to 56 years, with a mean age of 34 years). The result summarized in table 1, 2 and 3. VEP wave patterns were similar and easily reproducible with those different types of visual stimulation. As compared of normal values of pattern reversal and LED stimulating visual evoked responses, there are no significant variations of absolute latencies, amplitudes, absolute amplitude differences between two eyes, proportional amplitude differences between eyes, and duration differences between two eyes. Only differences were significant in latency differences between two eyes and duration of p. 100. These results suggest that pattern reversal and LED stimulating VEP test will be useful in clinical test according to various patient's conditions.
