ABSTRACT
OBJECTIVE@#To study the character of the PRVEPs evoked by different stimulation fields in normal-vision subjects and its value in forensic medicine.@*METHODS@#The PRVEPs were evoked by full-field, central-field and peripheral-field respectively in 30 subjects (60 eyes) and the latency and amplitude of N1 and P1 were analyzed.@*RESULTS@#There was no statistically significant difference in the latency and amplitude of PRVEPs between right and left eyes. The appearance probability of all the waves was 100% at the different stimulations but that of N1 was 36.77% at the central-field. There was statistically significant difference in the latency of N1 at the full field and peripheral field stimulations and there was no statistically significant difference in the amplitude. There was statistically significant difference in the latency and amplitude of P1 at the full field, central field and peripheral field stimulation.@*CONCLUSION@#The PRVEPs evoked by different field stimulations can be used to evaluate the functions of the different area retina and can be used to identify the exaggerated or pretended visual dysfunction.
