Surgical treatments of proliferative vitreoretinopathy.
Four hundred ten eyes with retinal detachment and proliferative vitreoretinopathy underwent closed vitrectomy with membrane peeling, scleral buckling, and intraocular air injection. The retina was reattached in 243 eyes (59.3%). Useful vision was attained in 223 eyes. The preoperative proliferative vitreoretinopathy was clinically graded in six groups of increasing severity (C-1, C-2, C-3, D-1, D-2, D-3). From grades C-2 to D-3, a significant trend related a decreased rate of retinal reattachment with increased severity. However, grade C-1 showed a significantly lower success rate than did grade C-2. Scleral buckling alone may be the treatment of choice in grade C-1 eyes. Grade D-3 eyes had the worst anatomic and functional results. Preoperatively, there was a significant relationship between increasing severity of proliferative vitreoretinopathy and frequency of aphakia, and aphakic eyes showed a significantly lower rate of retinal reattachment than did phakic eyes.
