PURPOSE
To report the clinical features of tractional internal limiting membrane (ILM) detachment in highly myopic eyes with posterior staphyloma.
DESIGN
Observational case report.
METHODS
We reviewed the optical coherence tomography images of 249 eyes in the high myopia clinic. ILM detachment was observed in six eyes (2.4%). We investigated the clinical feature of this finding.
RESULTS
Myopic foveoschisis (MF) was present in four of the six eyes (67%) (six patients, two men and four women; mean age, 57.3 years). The mean axial length was 29.3 mm and the mean refractive error was -15.0 diopters. The best-corrected visual acuity levels ranged from 20/400 to 20/13.
CONCLUSIONS
Rigidity of the ILM seems to cause tangential traction and results in a major cause of a disease specific to high myopia; that is, MF.
目的
报告高度近视合并后巩膜葡萄肿患者的牵引性内界膜（ILM）脱离的临床特征。
设计
观察性病例报告。
方法
我们回顾了高度近视门诊249只眼的光学相干断层扫描图像。在6只眼（2.4%）中观察到ILM脱离。我们研究了这一发现的临床特征。
结果
6只眼中有4只眼（67%）存在近视性黄斑劈裂（MF）（6例患者，2例男性和4例女性；平均年龄57.3岁）。平均眼轴长度为29.3mm，平均屈光不正为-15.0屈光度。最佳矫正视力范围为20/400至20/13。
结论
ILM的僵硬似乎会导致切线牵引，并导致高度近视特有的一种疾病的主要原因，即MF。
