Abstract:
Objective To observe the changes of the multifocal electroretinograph (mf-ERG) in commotio retinae. Methods The affected eyes (traumatic group) and the fellow eyes (control group) of 31 patients with unilateral commotio retinae were examined by RETI scan 3.15 system. The responses of 61 retinal regions were recorded, and the average amplitude densities of the N 1 (the first negative) wave and P 1 (the first positive) wave in different regions of retinal were analyzed. Results The average amplitude densities of 1-4 rings in N 1 wave and 1-5 rings in P 1 wave were much lower in traumatic group than those in the control. Conclusions The average amplitude densities of N 1 wave and P 1 wave of mf-ERG in retinal affected regions decreases markedly in eyes with commotio retina; mf-ERG may provide the quantificational and orientational detection for the visual ability of the eyes with commotio retinae.
