To study the characteristics of optical coherence tomography (OCT) in idiopathic macular epiretinal membranes (IMEM) and the relationship between the thickness of fovea and the vision of affected eyes.
A total of 67 cases (73 eyes) with clinical diagnosis of IMEM using direct, indirect ophthalmoscope, three mirror contact lens, fundus color photography or fundus fluorescein angiography (FFA) were examined with OCT.
Epiretinal membranes (ERMs) with macular edema were found in 32 eyes, proliferative ERMs in 20 eyes, ERMs with macular pseudoholes in 14 eyes and ERMs with laminar macular holes in 7 eyes. Based on OCT, the ERMs were clearly and partially seperated from the retinal (27 eyes, 38. 36%), the retinal thickness of the fovea was the thickest in the proliferative ERMs and the thinnest in the ERMs with laminar macular holes. The statistical analysis showed there was a negative correlation between the thickness of fovea and visual acuity (r = - 0. 454, P = 0. 000).
There were four types of images of OCT in IMEM: ERMs with macular edema, proliferative ERMs, ERMs with macular pseudohole and ERMs with laminar macular hole; and the thicker the fovea under the OCT, the poorer the vision acuity in the affected eyes with ERMs.
研究光学相干断层扫描（OCT）在特发性黄斑视网膜前膜（IMEM）中的特征以及黄斑中心凹厚度与患眼视力之间的关系。
对67例（73只眼）经直接检眼镜、间接检眼镜、三面镜接触镜、眼底彩色照相或眼底荧光血管造影（FFA）临床诊断为IMEM的患者进行OCT检查。
发现32只眼存在伴有黄斑水肿的视网膜前膜（ERM），20只眼为增殖性ERM，14只眼为伴有黄斑假性裂孔的ERM，7只眼为伴有板层黄斑裂孔的ERM。基于OCT，ERM与视网膜清晰且部分分离（27只眼，38.36%），增殖性ERM中黄斑中心凹的视网膜厚度最厚，而伴有板层黄斑裂孔的ERM中最薄。统计分析显示，黄斑中心凹厚度与视力之间存在负相关（r = -0.454，P = 0.000）。
IMEM的OCT图像有四种类型：伴有黄斑水肿的ERM、增殖性ERM、伴有黄斑假性裂孔的ERM和伴有板层黄斑裂孔的ERM；OCT下黄斑中心凹越厚，患有ERM的患眼视力越差。
