To evaluate the results of pars plana vitrectomy and membrane stripping for idiopathic and secondary preretinal macular membrane (PMM).
Twenty one consecutive subjects (21 eyes) ranging in age from 40 to 78 (mean 66.9) with PMM underwent vitrectomy and membrane peeling. 17 cases had membranes that were considered idiopathic, and 4 cases were associated with other disorders: 3 occurred after successful retinal reattachment surgery, 1--after laserotherapy in the course of diabetic retinopathy. Visual acuity (VA), Amsler grid, and postoperative complications were assessed. The follow-up was 1 to 22 months, mean 5.7.
Visual acuity improved postoperatively in 15 eyes (71.4%), at least two lines on the Snellen chart in 8 eyes (38.1%), entirely in patients with idiopathic PMM. It remained unchanged in 3 eyes (14.3%) and deteriorated in 3 eyes (14.3%). Eyes with transparent membrane showed greater visual improvement than opaque ones. The preoperative Amsler test was positive in 15 patients (71.4%), postoperatively--in 4 cases (19%). 2 idiopathic cases with VA of 0.7 showed postoperatively VA of 1.0. Complications included retinal detachment in 2 eyes (1 in idiopathic and 1 in secondary PMM), and development of nuclear sclerotic cataract in 2 eyes. At 6 months of follow-up, a residual membrane formation in 1 cases appeared. Macular pseudohole was observed in 1 eye with no impact on visual results.
评估经平坦部玻璃体切除术及视网膜前黄斑前膜（PMM）剥除术治疗特发性及继发性PMM的效果。
连续21例年龄在40至78岁（平均66.9岁）的PMM患者（21只眼）接受了玻璃体切除术及膜剥除术。17例患者的膜被认为是特发性的，4例与其他疾病相关：3例发生于视网膜复位手术成功后，1例发生于糖尿病性视网膜病变激光治疗后。评估了视力（VA）、Amsler方格表检查结果及术后并发症。随访时间为1至22个月，平均5.7个月。
15只眼（71.4%）术后视力提高，8只眼（38.1%）在Snellen视力表上至少提高两行，均为特发性PMM患者。3只眼（14.3%）视力保持不变，3只眼（14.3%）视力下降。透明膜的眼比不透明膜的眼视力改善更明显。术前Amsler检查15例（71.4%）为阳性,术后4例（19%）为阳性。2例视力为0.7的特发性病例术后视力达到1.0。并发症包括2只眼发生视网膜脱离（特发性PMM和继发性PMM各1只眼），2只眼出现核性硬化性白内障。随访6个月时，1例出现残留膜形成。1只眼观察到黄斑假孔，但对视力结果无影响。
