Visual loss in eyes with full-thickness macular holes is thought to be caused by the absence of retinal function in the area of the neurosensory defect as well as reduction in retinal function in the surrounding area of neurosensory retinal detachment. To improve characterization of the visual function of eyes after successful macular hole surgery, we studied six eyes preoperatively and postoperatively with macular microperimetry using the scanning laser ophthalmoscope. Best-corrected visual acuity was improved postoperatively in all eyes. Microperimetry performed preoperatively demonstrated an absolute scotoma that corresponded to the neurosensory defect in all eyes, with surrounding concentric isopters of relative scotomata. No detectable absolute scotoma was found in any eye postoperatively. All eyes showed partial or complete resolution of the surrounding relative scotomata. Improvements in visual acuity after successful macular hole surgery may be related to disappearance of a detectable absolute scotoma as well as improvement in the surrounding retinal function.
全层黄斑裂孔眼的视力丧失被认为是由神经感觉缺陷区域视网膜功能缺失以及神经感觉性视网膜脱离周围区域视网膜功能降低所致。为了更好地描述黄斑裂孔手术成功后眼睛的视觉功能，我们使用扫描激光检眼镜对6只眼在黄斑微视野检查术前和术后进行了研究。所有眼睛术后最佳矫正视力均有提高。术前进行的微视野检查显示，所有眼睛均存在与神经感觉缺陷相对应的绝对暗点，周围有相对暗点的同心等视线。术后任何一只眼睛均未发现可检测到的绝对暗点。所有眼睛周围相对暗点均部分或完全消退。黄斑裂孔手术成功后视力的提高可能与可检测到的绝对暗点消失以及周围视网膜功能改善有关。
