ABSTRACT

OBJECTIVE:

The purpose of this study was to evaluate the relationship between the visual acuity and visual evoked potentials of the amblyopia patients and normal persons for the demonstration of the visual disability.

METHOD:

We performed visual evoked potential study, in 49 eyes of the 43 amblyopia patients and in 76 eyes of 38 normal young adults. Our study was carried out to evaluate the relationship of the visual acuity with N1, P1, N2, P2 latency, P1-N2 amplitude and to compare the latency of N1, P1, N2, P2, and P1-N2 amplitude in amblyopia patients and normal young adults.

RESULTS:

The mean values of N1, P1, N2, P2 latency were prolonged in amblyopia patients compared to normal young adults (p 0.05), but significant correlation was noted between the visual acuity and P1-N2 amplitude (p <0.05).

CONCLUSION:

These results showed prolonged latency of N1, P1, N2, P2 in amblyopia group as well as significant correlation between visual acuity and P1-N2 amplitude in both groups. So, P1 latency and P1-N2 amplitude are good parameters in evaluating the visual disability.
