To evaluate the surgical outcome of vitrectomy and foveal thickness before and after vitrectomy for idiopathic epiretinal membranes.
Twenty-three eyes of 21 patients with idiopathic epiretinal membranes were analyzed. The mean follow-up period was 17.8 months. In 16 eyes of 14 patients, foveal thickness was measured by optical coherence tomography (OCT).
Preoperative visual acuity ranged from 0.1 to 0.7. Postoperatively, 17 eyes achieved a final visual acuity of 1.0 or better, and 21 eyes achieved 0.5 or better. Preoperative foveal thickness ranged from 205 to 575 microns (mean +/- standard deviation, 409.9 +/- 103.3 microns). Postoperatively, mean foveal thickness was 347.7 +/- 106.0 microns (1 week follow up), 338.6 +/- 103.7 microns (2 months), 304.6 +/- 97.0 microns (6 months), and 274.3 +/- 78.7 microns (1 year). There was a weak negative correlation between visual acuity and foveal thickness.
Visual acuity improves significantly after surgery. OCT is useful for idiopathic epiretinal membrane surgery.
评估特发性视网膜前膜玻璃体切除术的手术效果以及玻璃体切除术前、后的黄斑厚度。
分析21例特发性视网膜前膜患者的23只眼。平均随访时间为17.8个月。14例患者的16只眼中，采用光学相干断层扫描（OCT）测量黄斑厚度。
术前视力范围为0.1至0.7。术后，17只眼最终视力达到1.0或更好，21只眼达到0.5或更好。术前黄斑厚度范围为205至575微米（平均值±标准差，409.9±103.3微米）。术后，黄斑平均厚度在术后1周为347.7±106.0微米，术后2个月为338.6±103.7微米，术后6个月为304.6±97.0微米，术后1年为274.3±78.7微米。视力与黄斑厚度之间存在弱负相关。
手术后视力显著提高。OCT对特发性视网膜前膜手术有用。
