目的.目的：采用面光谱域光学相干断层扫描（SD-OCT）技术对特发性全层黄斑裂孔（FTMH）术后视网膜内层缺损（称为同心圆黄斑暗斑（CMDS））的表现进行描述。在一项回顾性队列研究中，作者评价了36例（36只眼）接受标准三孔睫状体平坦部玻璃体切除术联合内界膜（ILM）剥离的大型特发性MH（>400 μ m）患者。所有患者在术前和术后使用B扫描和C扫描面SD-OCT进行分析，以确定视网膜表面的OCT模式。平均随访时间为10个月（± 8.45 SD;范围：3-30个月）。术后3个月，36/36只眼（100%）在正面SD-OCT图像上显示CMDS外观。单次手术后解剖成功率为100%（36/36眼）。一旦它们变得明显，在视网膜表面上观察到的这些暗斑就不会进行性，并且随着时间的推移保持稳定。特发性MH手术后，当ILM剥离时，经常发生视网膜内缺损。据作者所知，该特征之前未使用正面SD-OCT成像报告，并且其由视神经纤维相同方向的多个CMDS组成。研究中的所有患者均在术后3个月显示出这种典型的OCT模式。因此，作者认为，这是一个有用的，非侵入性的技术，以评估完整的ILM去除FTMH手术，如果CMDS的外观在视网膜表面的报告。（Invest Ophthalmol维斯科学。2011;52：8349-8355）DOI：10.1167/iovs.11-8043
PURPOSE. To describe the appearance of inner retinal defects using en face spectral domain optical coherence tomography (SD-OCT) after idiopathic full-thickness macular hole (FTMH) surgery, referred to as concentric macular dark spots (CMDS).METHODS. In a retrospective cohort study, the authors evaluated 36 eyes of 36 patients with large idiopathic MH (>400 mu m) who underwent standard three-port pars plana vitrectomy with internal limiting membrane (ILM) peeling. All patients were analyzed using B-scan and C-scan en face SD-OCT before and after surgery to determinate the OCT pattern of the retinal surface.RESULTS. Mean follow-up was 10 months (+/- 8.45 SD; range, 3-30 months). Three months after surgery 36 of 36 eyes (100%) showed a CMDS appearance on en face SD-OCT images. Anatomic success rate was 100% (36/36 eyes) after a single surgical procedure. Once they were evident, these dark spots observed on the retinal surface were not progressive and remained stable over time.CONCLUSIONS. Inner retinal defects frequently occurred after idiopathic MH surgery when ILM was peeled. To the authors' knowledge, this feature has not been previously reported using an en face SD-OCT imaging, and it consisted of numerous CMDS in the same direction of the optic nerve fibers. All patients in the study showed this typical OCT pattern 3 months after surgery. Thus, the authors suggest that this is a helpful, noninvasive technique to assess complete ILM removal in FTMH surgery if CMDS appearance on the retinal surface is reported.
