Proliferative vitreoretinopathy and retinal detachment: surgical results with scleral buckling

ABSTRACT

This is a prospective study of 127 cases of retinal detachment with different stages of PVR, and evaluates the efficacy of scleral buckling alone in the treatment of rhegmatogenous retinal detachment with different stages of PVR. The overall anatomic success rate, after at least six months of follow-up was 65.3%. The anatomic success rate depends on two important factors 1] severity of PVR the success rate decreased with increasing severity of PVR. 2] size of break reattachment rate was higher for eyes with smaller breaks than for eyes with larger breaks and was least when no break was found. 90.3% of the cases achieved a visual acuity of counting fingers or better. Prognosis for visual improvement after successful scleral buckling was unrelated to the preoperative severity of PVR. None of the anatomically successful cases had a final visual acuity of no light perception. The overall prognosis for phakic patients was better than for aphakics. The difference in success rate, between those treated with implant was not significant. High myopia did not influence the overall anatomic success rate. Cases of giant tear and dialysis were treated successfully by scleral buckling alone with excellent follow-up [83.3%] results:
