Macular detachment causes visual deterioration in 25-75% of patients with congenital optic disc pit. A number of treatment options have been reported to manage the macular detachment in optic pit. An optic disc pit represents a defect in the lamina cribrosa; theoretically, an ideal procedure to treat optic pit associated macular detachment would be one that prevents the flow of fluid across the pit by creating an additional barrier. We present a new surgical technique that employs an autologous internal limiting membrane (ILM) to create this barrier. The technique involves standard vitrectomy along-with ILM peeling. Subsequently, the peeled ILM was inverted and transplanted onto the optic disc pit to close the optic nerve pit. This technique showed satisfactory anatomic result with good functional improvement in visual acuity.
黄斑脱离在25%至75%的先天性视盘凹陷患者中会导致视力下降。据报道,有多种治疗方案可用于处理视盘凹陷中的黄斑脱离。视盘凹陷代表筛板的缺损;从理论上讲,治疗与视盘凹陷相关的黄斑脱离的理想手术应是通过建立额外屏障来阻止液体流经凹陷的手术。我们提出一种新的手术技术,该技术采用自体内界膜(ILM)来建立这种屏障。该技术包括标准玻璃体切除术及ILM剥除术。随后,将剥下的ILM翻转并移植到视盘凹陷处,以封闭视神经凹陷。该技术显示出令人满意的解剖学结果,视力有良好的功能改善。
