To evaluate macular function before and after successful surgical closure of idiopathic macular holes using multifocal electroretinogram (ERG).
40 patients (40 eyes) with idiopathic macular holes were examined using multifocal ERG both before and after vitreous surgery. The postoperative period was from 1 to 12 months.
Preoperatively, the electrical retinal response densities in the foveal and the perifoveal area were apparently decreased. After a mean postoperative period of 3-6 months, the foveal and perifoveal area electrical retinal response densities improved to two to four times the preoperative level and the improvement continued to 1 year after surgery.
In macular holes, the decrease in retinal electrophysiological response was not limited to the fovea but involved an area of the perifovea of 1.6 disc diameters. The electrical retinal response density of these areas gradually improved after macular hole closure.
使用多焦视网膜电图（ERG）评估特发性黄斑裂孔成功手术封闭前后的黄斑功能。
对40例（40眼）特发性黄斑裂孔患者在玻璃体手术前后均进行多焦ERG检查。术后时间为1至12个月。
术前，黄斑中心凹及中心凹周围区域的视网膜电反应密度明显降低。术后平均3至6个月时，黄斑中心凹及中心凹周围区域的视网膜电反应密度提高到术前水平的两到四倍，且术后1年仍持续改善。
在黄斑裂孔中，视网膜电生理反应的降低不仅限于黄斑中心凹，还累及直径为1.6个视盘直径的中心凹周围区域。黄斑裂孔封闭后，这些区域的视网膜电反应密度逐渐改善。
