目的探讨特发性黄斑裂孔修补术后黄斑裂孔角度等光谱域光学相干断层扫描（SD-OCT）参数与术后解剖及视力的相关性。观察玻璃体黄斑牵引力、黄斑裂孔处的视网膜前膜和囊状边缘等定性参数，以及裂孔顶部最大直径、边缘间最小直径、鼻侧和颞侧垂直高度、最长基底直径和视网膜边缘与视网膜色素上皮之间的黄斑裂孔角度等定量参数。计算黄斑裂孔指数（MHO）、直径裂孔指数（Diameter Hole Index）和牵引裂孔指数（Tractional Hole Index）。以最终视力（VA）和闭合类型为因变量，SD-OCT参数为自变量，分别进行单因素和多因素回归分析。
Aim To evaluate correlation of various spectral-domain optical coherence tomography (SD-OCT) parameters including macular hole angle as well as various indices with anatomical and visual outcomes after idiopathic macular hole repair surgery.Methods Retrospective study of 137 eyes of 137 patients who underwent idiopathic macular hole repair surgery between January 2008 and January 2014 was performed. Various qualitative parameters such as presence of vitreomacular traction, epiretinal membrane and cystic edges at the macular hole as well as quantitative parameters such as maximum diameter on the apex of the hole, minimum diameter between edges, nasal and temporal vertical height, longest base diameter and macular hole angle between the retinal edge and the retinal pigment epithelium were noted. Indices including hole form factor, Macular Hole Index (MHO, Diameter Hole Index and Tractional Hole Index (THI) were calculated. Univariate and multivariate regression analysis was performed separately for final visual acuity (VA) and type of closure as dependent variable in relation to SD-OCT parameters as independent variables.Results On multivariate regression only minimum diameter between edges (p
