摘　　要：目的:分析频域光学相干断层扫描(SD-OCT)参数评估黄斑裂孔内界膜撕除术后视力改善情况的应用价值。方法:回顾性分析2019-05/2021-02于我院行玻璃体切除+内界膜撕除+长效气体填充术治疗的特发性黄斑裂孔(IMH)患者82例82眼的临床资料,分析术后3mo IMH闭合情况与SD-OCT参数的相关性,并评估影响术后视力改善不良的危险因素。结果:Spearman秩相关分析显示,术后3mo IMH闭合情况与术前外界膜(ELM)缺损直径呈正相关(r_(s)=0.308,P<0.05),与术前黄斑裂孔指数(MHI)呈负相关(r_(s)=-0.266,P<0.05)。Logistic回归分析显示,术前MHI≥0.5是影响术后视力改善不良的保护因素(OR=0.691,P<0.05)。结论:SD-OCT可通过检测术前MHI及ELM缺损直径等参数预测手术疗效,对判断视功能改善情况有利。AIM:To analyze the application value of spectral domain-optical coherence tomography(SD-OCT)parameters on evaluating visual acuity improvement after internal limiting membrane peeling of macular hole.METHODS:The retrospective analysis was performed on the clinical data of 82 patients(82 eyes)with idiopathic macular hole(IMH)who underwent vitrectomy+internal limiting membrane peeling+long-acting gas tamponade in the hospital between May 2019 and February 2021.The correlation between IMH closure and SD-OCT parameters at 3mo after surgery was analyzed,and the risk factors for poor postoperative visual acuity improvement were evaluated.RESULTS:Spearman rank correlation coefficient analysis showed that IMH closure at 3mo after operation was positively correlated with preoperative external limiting membrane(ELM)defect diameter(r_(s)=0.308,P<0.05),and it was negatively correlated with preoperative macular hole index(MHI;r(s)=-0.266,P<0.05).Logistic regression analysis revealed that preoperative MHI≥0.5 was a protective factor affecting poor postoperative visual acuity improvement(OR=0.691,P<0.05).CONCLUSION:SD-OCT can predict the surgical efficacy by detecting the preoperative MHI and ELM defect diameter,and it is beneficial to judging the improvement of visual function.
