目的观察基于OCT不同分期的特发性黄斑前膜(IMEM)手术前后视力及黄斑微结构的改变。方法选取2021年10月至2023年1月于沧州爱尔眼科医院确诊为IMEM的患者82眼纳入研究,所有患者行25G经睫状体扁平部玻璃体切除联合黄斑前膜及内界膜(ILM)...目的观察基于OCT不同分期的特发性黄斑前膜(IMEM)手术前后视力及黄斑微结构的改变。方法选取2021年10月至2023年1月于沧州爱尔眼科医院确诊为IMEM的患者82眼纳入研究,所有患者行25G经睫状体扁平部玻璃体切除联合黄斑前膜及内界膜(ILM)剥除、空气填充,其中59眼联合白内障超声乳化摘除、人工晶体植入术。依据2017年IMEM分期标准分为A组21眼(2期),B组39眼(3期),C组22眼(4期)。分别于术前及术后3个月行最佳矫正视力(BCVA)、光学相干断层成像(OCT)检查。结果3组术后BCVA(LogMAR)较术前均降低(P均<0.05)。术前3组比较BCVA(LogMAR)差异无统计学意义(P>0.05);术后3组BCVA(LogMAR)比较差异有统计学意义(P<0.05),两两比较差异均有统计学意义(P均<0.05)。A组术后黄斑中心凹厚度(CMT)较术前差异无统计学意义(P=0.393);B组和C组术后CMT较术前均降低(P均<0.01)。术前3组CMT比较差异有统计学意义(P<0.05),两两比较差异均有统计学意义(P均<0.05);术后3组CMT比较差异有统计学意义(P<0.01),A组和B组、A组和C组比较差异均有统计学意义(P均<0.01),B组和C组比较差异无统计学意义(P>0.05)。82眼术后BCVA(LogMAR)与术前BCVA(LogMAR)、术前CMT、术后CMT均呈正相关(P均<0.01)。En face OCT发现7眼黄斑区可见同心圆状改变,B扫描呈柱状或锯齿状改变。结论特发性黄斑前膜患者OCT分期越早,术后视力及黄斑微结构恢复越好。应用OCT进行分期可以为手术时机选择及预后判断提供重要的依据。展开更多
