AIM:To investigate the clinical effect of scleral buckling with nondrainage of subretinal fluid in the treatment of rhegmatogenous retinal detachment.

METHODS: A total of 111 patients(113 eyes)with rhegmatogenous retinal detachment in our hospital from January 2012 to January 2017 were retrospectively reviewed. All the patients were identified as fulfilling the criteria of rhegmatogenous retinal detachment. Localization and scleral cryotherapy of retinal breaks with binocular indirect ophthalmoscopy in all eyes were performed during the operations. Simple scleral pressure were performed in 98 eyes. Intravitreal injection of sterile air were performed in 15 eyes. Scleral cryotherapy were performed in all cases with retinal degeneration and breaks. Anterior chamber puncture were performed before ligation suture. The final retinal reattachment rate, best corrected vision acuity, intraocular pressure and complications were observed.

RESULTS: The mean follow-up period was 6mo after operation. The final retinal reattachment rate at 6mo was 97.4%. There were 91 eyes(80.5%)with improved visual acuity after operation. High intraocular pressure can be controlled after operation. Complications were occurred in 7 eyes in the operation, 3 eyes postoperatively.

CONCLUSION: The surgery of scleral buckling with nondrainage of subretinal fluid have few complications and is effective.
