Abstract

Objective:To evaluate the effect of vitrectomy in the proliferative vitreoretinopathy(PVR).Methods:21 cases of PVR(≥Grade-C2) with retinal detachment were treated by vitrectomy and scleral encircling buckling, membrane peeling, retinotomy, and gas or silicon oil tamponade.Results:The retina was reattached in a rate of 78.9% in 2～9 months postoperatively, visual acuity improved significantly in 20 eyes(95.2%). 4 eyes failed because of PVR recurrent.Conclusion:Modern vitrectomy is optimal operation for PVR. The most important technique is membrane peeling and eliminating the traction of vitreous base. PVR recurrent is major cause of failure.
