AIM:To discuss the therapeutic effect,surgical indication of scleral buckling for rhegmatogenous retinal detachment(RRD).METHODS:The major surgeries were as follows:retinal breaks locating,cryotherapy,scleral buckling or encircling scleral buckling.192 cases 195 eyes with RRD accepted surgery,including 131 eyes in segmental scleral buckling and 64 eyes in encircling scleral buckling.Among these cases 145 eyes underwent subretinal fluid drainage and 16 eyes with gas filing into vitreous space.RESULTS:The rate of retinal reattachment after one surgical procedure was 94.9%.The postoperative visual acuity increased significantly,which had statistical difference compared with that of the preoperative(P<0.05)And there were no serious complications in operation and postoperation.CONCLUSION:Scleral buckling appears to be safe and effective in patients with RRD.
