Objective 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 plusmn;26.6 deg;horizontally and  plusmn;22.1 deg;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 lt;0.01). The amplitude densities of b wave at detached area, attached area in RD eyes and at the retina in normal eyes were (3.44 plusmn;2.85), (6.34 plusmn;3.31),(21.32 plusmn;6.48) nV/deg2 respectively. There was statistically significant difference among them (P lt;0.05). Conclusion MERG can evaluate objectively and quantitatively the visual function at macular area, posterior polar detached area and attached area in RD. (Chin J Ocul Fundus Dis,2000,16:244-247)
