方法：根据术前OCT检查显示的视网膜各层形态的完整状况将80例81眼患者分为完整组和不完整组，所有患者均进行玻璃体切割联合黄斑前膜剥除手术，术后12wk重新对所有患者进行检查，对检查结果进行比较。

结果：术前OCT显示外层视网膜结构不完整的患者术后视力的改善程度好于术前外层视网膜结构完整者，不完整组平均LogMAR BCVA由0.81±0.42变为0.45±0.27； 术前视网膜结构完整者术后视力与术前视力比较没有明显的变化，完整组平均LogMAR BCVA由0.41±0.19变为0.35±0.22； 所有患者术后视力都有一定程度改善，术后平均LogMAR BCVA为0.42±0.14，平均黄斑中心凹厚度(central fovea thickness，CFT)为387.08±108.35μm，经比较，以上项目均具有统计学差异(P<0.05)。

结论：特发性黄斑前膜患者术前进行OCT检查对预测术后视力有价值，对患者是否选择手术治疗有积极的临床意义。

METHODS:Eighty patients(81 eyes)were divided into complete and incomplete group by the conditions of preoperative OCT examination showed retinal layers. All the patients were given vitrectomy and macular membrane peeling, 12wk after operations all patients were examined again. The results were compared.

RESULTS:Preoperative OCT revealed that the improved degree of visual acuity after operations in incomplete group in which the outer retinal structure was not complete was better than that in complete group in which the outer retinal structure was complete before operations. The average LogMAR BCVA of incomplete group improved from 0.81±0.42 to 0.45±0.27. The visual acuity of complete group didn't show significant change after operations. The average LogMAR BCVA of complete group improved from 0.41±0.19 to 0.35±0.22. The visual acuity of all patients after operations were improved to a certain extent. The average postoperative LogMAR BCVA was 0.42±0.14. The average central fovea thickness(CFT)became 387.08±108.35μm. The above projects had significant differences after statistical analysis(P<0.05).

CONCLUSION:Preoperative OCT in patients with IMEM has the value to predict postoperative visual acuity, and has optimistic clinical effect on whether or not to choose the operation.
