RESUMEN
A total of 30 eyes of 30 patients with primary rhegmatogenous [retinal detachment [RD] complicated by proliferative vitreoretinopathy [PVR] were treated by cryopexy and scleral buckling alone. The patients were followed up for at least 6 months after the operation, the eyes of the 30 patients were divided into three groups: Group A [13 eyes - minimal PVR]: showed vitreous haze and vitreous pigment clumps. Group B [10 eyes - moderate PVR] showed wrinkling of the inner retinal surface, rolled edge of retinal break, retinal stiffness and vessel tortousity. Group C-1 [7 eyes - marked PVR] showed full thickness fixed retinal folds affecting one retinal quadrant. In group A, a final success rate [after second operation] of 76.8% was reached. This rate declined to 70% in group B then 57.1% in group C-1. The overall success rate was 69.9%. Vision better than counting fingers was achieved in 90% of cases of group A, 71.4% in group B and 56% in group C-1
