Abstract: Objective To explore the partial function of the macular area before and after idiopathic macular hole surgery with multifocal ERG (mfERG). Methods Macular hole standard three-line incision vitreous stage III and IV patients with idiopathic cutting-linking and 0.05%indocyanine green stained internal limiting membrane peel plus 20%SF6 gas-iflled treatment, preoperative and postoperative line mfERG were used in the study. Results 1 and 2-ring surgery in patients with a ifrst-order reaction function of P1 wave density were signiifcantly reduced compared with normal eyes. 1 and 2-ring P1 response densities macular hole healing after eye surgery mfERG first-order function of the gradual increased, central peak postoperative mfERG three-dimensional topographic map of gradual recovered, but still lowered than the normal eyes after 6 months. Conclusion mfERG can accurately relfect the local function of the macular area.
