ABSTRACT
VEPs weie recorded in 222 cases of different disease groups and in 42cases of the control group using a Nicolet CA 1000 system. The latency time of N1, P1, N2, and P2 from the prominent surface peak and the P1-N2 amplitude at full field pattern reversal VEP. The score of each disease group was compared with those of the control group. The results are as follows; 1. Functional amblyopia, optic neuritis, and optic nerve atrophy patients presented a significant derrease in amplitude in comparison to normal subiects. 2. In the P1 implicit time, optic neuritis, and optic nerve atrophy patients presented a marked delay. Functional amblyopia patients presented a moderate delay while other disease group patients presented normal to mild delays. 3. More than half of the optic neuritis and optic nerve atrophy patients presented a detraction of the P1 wave form.
