·AIM:To compare the clinical results of laser photocoagulation and cryopexy in the scleral buckling of rhegmatogenous retinal detachment.·METHODS:The results of 42 eyes treated with laser photocoagulation and 39 eyes treated with cryopexy from February 2007 to August 2009 were analysed.·RESULTS:Retinal detachment in photocoagulation group had an anatomic success rate of 100% with one surgical procedure.Retinal detachment eyes with retinal cryopexy had a success rate of 94.9% with one operation.The postoperative visual acuity of 37 eyes(88%)in photocoagulation group was impoved.The postopertive visual acuity of 29 eyes(74%)in cryopexy group was impoved,there was no difference between them(P>0.05).·CONCLUSION:Treating the rhegmatogenous retinal detachment by laser photocoagulation in scleral buckling is as simple and effective as cryopexy.·
