增殖性玻璃体视网膜病变性视网膜脱离的手术治疗

报告189例189眼严重增殖性玻璃体视网膜病变(PVR)性视网膜脱离，单纯巩膜扣带术和玻璃体切除术的结果，平均解剖成功率63%，从C₁87.5%至D₃30.4%。术后复位成功的病例95.8%有指数以上的视力，但仅26.9%达0.1以上，且多集中于C₁和C₂组。手术失败的主要原因是新的或复发的前段PVR形成(51.4%)，其次为后部视网膜前膜增殖，将原裂孔拉开或形成新裂孔(25.7%)。就PVR性视网膜脱离的手术时机，手术方式及前段PVR的形成进行了讨论。（中华眼底病杂志，1994，10：199-202）

SURGICAL TREATMENT FOR RETINAL DETACHMENT WITH PROLIFERATIVE VITREORETINOPATHY

ne hundred and eighty-nine cases of retinal detachment complicated with advanced pro-liferative vitreoretinopathy(grade C or D)were treated with scleral buckling or vitreoussurgery,The reattachment rate was63%.ranging from 87.5%in grade C1 to 30.4%in gradeD3.Retinas were reattached in 119,of which the postoperative visual acuity was counting fin-ger or better in 95.8%and 20/200 or better in 26.9%in those cases,of grade C1 to C2 with-out proliferative vitreoretinopathy;The major causes of surgical failure weredevelopment ofnew or recurrent anterior PVR(51.4%)posterior epiretinal proliferation making pre-exist-ing retinal breaks open and creation of new breaks(25.7%).Finally,we discussed the time ofvitreoretinal surgery,methods of operation and the formation of anterhr PVR.
