Abstract:
Objective [WT5”BZ]To explore significance of multifocal ERG(MERG) in evaluating visual function in patients with retinal detachment(RD). Methods MERG was tested using VERIS 4.0 visual evoked response imaging system for 21 patients with retinal detachment (22 eyes) and 36 normal subjects (42 eyes). The stimulative visual angles subtended ?26.6? horizontally and ?22.1? vertically. Burian Allen contact lens electrode was used to record the responses from 103 retinal locations in 8 min (16 segments). Results The latencies of a wave and b wave at the 4 quadrans, macular area and extra macular area in RD group were significantly delayed and their amplitudes markedly decreased comparing with normal group (P
