随着技术水平不断提高，光学相干断层扫描(optical coherence tomography，OCT)对特发性黄斑裂孔(idiopathic macular hole，IMH)术后效果的评估有着越来越重要的价值。术前测量的黄斑裂孔最小直径、裂孔基底最大直径、裂孔最大高度、黄斑裂孔指数、裂孔形成因子、裂孔牵拉指数、黄斑裂孔愈合指数、光感受器内外节连接、中心凹视锥细胞外节尖端线、中心子区视网膜厚度以及黄斑裂孔内口直径等形态学参数与术后视力和裂孔解剖复位情况存在一定相关性。认识各种预测指标、熟悉其价值有助于手术者直观地对术后情况进行判断，也有助于加深对黄斑裂孔形态、功能学改变的了解。

[Abstract]
Accompanying with the development of technological level, optical coherence tomography plays a more and more important role in predicting the surgical outcome for idiopathic macular hole. Preoperative morphologic parameters like minimum diameter, base diameter, maximum height, macular hole index, hole form factor, tractional hole index, macular hole closure index, photoreceptor inner-outer segment junction, cone outer segment tips line, central subfield retinal thickness and macular hole inner opening diameter were proved correlated to postoperative visual acuity and anatomical results. It has important application value to know these predictors to judge the surgical outcome and deepen understanding of idiopathic macular hole.
