scleral buckling with and without retinopexy and laser photocoagulation for treatment of rhegmatogenous retinal detachment

introduction: there are different methods to repair retinal detachment. in this trial the retinopexy in repairmen of retinal regmatogenesis rd is compared with other methods in qazvin teaching hospitals during 1993-2003. methods: this out come study was conducted on 47 patients with s/b and retinal break cryopexy (group i) , 30 patients undergoing s/b with barrier laser photocoagulation around retinal breaks (group ii) and 41 patients with s/b without retinopexy (group iii). an encircling or segmental buckle was placed for all eyes. in some patients, subretinal fluid drainage (sred) or anterior chamber paracentesis and intravitreal air dubble injection was performed. the patients were followed for 3 to 48 months. t. test, chi square and fisher exact test were used for data analysis. results: the groups were similar with respect to age, sex, lens status, visual acuity, type, number and location of break. there were no differences in the surgical procedure performed. the reattachment rate in group i was 91.5% , in group ii 86.7% and in group iii was 97.6%, a difference that was not significant. conclusions: with s/b procedure, retinal cryopexy does not seem to increase success rate of operation.
