目的：探讨黄斑裂孔不同大小、形态与预后的关系。方法回顾性分析30例特发性黄斑裂孔的临床资料、OCT影像学表现及术后视力。结果视力未提高组裂孔基底径、最小径高于视力提高组（P＜0．05），两组裂孔高度差异无统计学意义（P＞0．05）。Spearman相关性分析显示，术后视力改善与基底径（r＝-0．636）、最小径（r＝-0．469）呈负相关（P＜0．05）。结论特发性黄斑裂孔术前行OCT检查可通过裂孔基底径和最小径判断预后情况，其中基底径是更好的判断指标。“,”Objective To explore the prognostic factors of idiopathic macular hole based on form of the macular hole. Method The clinical data of 30 patients with idiopathic macular hole were retrospectively analyzed.Results The base diameter and minimum liner diameter of patients with improved visual acuity were smaller than those of patients without improved visual acuity,and there was a negative correlation between those two indicators and prognosis.The difference between height of macular holes had no statistical significance.Conclusion Base diameter and minimum liner diameter are good indexes for prognosis of idiopathic macular hole.
