To investigate the displacement of foveal retinal layers in surgically closed macular holes (MHs) after removal of the internal limiting membrane (ILM).
Medical records of 26 consecutive patients who underwent vitrectomy and removal of the ILM for idiopathic MH were retrospectively reviewed. En face optical coherence tomography images were exported at the level of the choroid, ellipsoid zone (EZ), and inner plexiform layer (IPL) at baseline and at 1, 3, and 6 months. The foveal center of the EZ and IPL was marked in the choroid en face image. The choroidal images were overlapped to match the vasculature in each patient, and the postoperative displacement of the foveal center was compared to baseline.
The center of the EZ and IPL was displaced significantly toward the disc during the first 3 months. The mean horizontal displacement at 1, 3, and 6 months was 52.7 μm, 112.5 μm, and 115.4 μm, respectively, for the EZ and 75.2 μm, 117.1 μm, and 136.5 μm, respectively, for the IPL. The location of the foveal center was significantly correlated between the EZ and the IPL (P ≤ .016).
The fovea was displaced nasally and slightly inferiorly after removal of the ILM. The displacement of the photoreceptor and inner retinal layers was concurrent. [Ophthalmic Surg Lasers Imaging Retina. 2019;50:414-422.].
研究去除内界膜（ILM）后手术封闭黄斑裂孔（MH）时黄斑区视网膜各层的移位情况。
回顾性分析26例因特发性MH接受玻璃体切除术并去除ILM的连续患者的病历。在基线、术后1个月、3个月和6个月时，导出脉络膜、椭圆体带（EZ）和内丛状层（IPL）水平的正面光学相干断层扫描图像。在脉络膜正面图像中标注EZ和IPL的黄斑中心。将脉络膜图像重叠以匹配每位患者的血管系统，并将黄斑中心的术后移位与基线进行比较。
在术后前3个月，EZ和IPL的中心显著向视盘移位。EZ在1个月、3个月和6个月时的平均水平移位分别为52.7μm、112.5μm和115.4μm，IPL分别为75.2μm、117.1μm和136.5μm。EZ和IPL的黄斑中心位置显著相关（P≤0.016）。
去除ILM后，黄斑向鼻侧及稍下方移位。光感受器层和视网膜内层的移位是同时发生的。[《眼科手术、激光与影像学视网膜》。2019；50：414 - 422。]
