摘　　要：目的采用频域光学相干断层扫描技术(special domain optical coherence tomography,SD-OCT)对先天性视盘小凹合并黄斑病变的发病机制进行探讨。方法回顾分析我院眼科2013年1月至2016年1月所诊治的先天性视盘小凹患者18例(18眼),对其SD-OCT结果进行分析总结。结果 18例患者中SD-OCT视盘处扫描均可见视盘小凹玻璃体条索牵拉,玻璃体牵拉可位于小凹的边缘或小凹的内部;视网膜神经上皮层脱离腔或劈裂腔存在与小凹相通的间隙和空间,这一间隙延伸至筛板以下区域,所有患者筛板结构不完整。同时所有患者均未见视网膜神经上皮层脱离腔或劈裂腔存在与玻璃体相通的间隙和空间。结论先天性视盘小凹并不是单一发病因素所引发,而是由于先天解剖异常加上玻璃体交界面上病理生理改变所导致。Objective To analyze the pathogenesis of congenital optic disc pit by special domain optical coherence tomography （SD-OCT）. Methods Eighteen patients （18 eyes） diagnosed as congenital optic disc pit in our hospital from January 2013 to January 2016 were retrospectively analyzed and their OCT scan results were analyzed and summarized. Results The vitreous traction were visible in 18 patients and vitre- ous traction may be located at the edge of the pit or inside a small concave; A communi- cating space or gap existed in all patients of the retinal detachment cavity or cavities of retinoschisis, where the gap extended to the area of the lamina cribiosa,lamina cribiosa structure was not complete in all patients. And all patients showed no communication between retinal and vitreous. Conclusion Congenital optic disc pit is not caused by a single factor, but due to congenital anatomical abnormalities and pathophysiological changes of interface of vitreous and retina.
