AIM:To explore the results of scleral buckling procedure without subretinal fluid drainage for old retinal detachment.METHODS: Clinical data of 32 patients (32 eyes) with old retinal detachment who underwent scleral buckling procedure without subretinal fluid drainage were retrospectively analyzed. Best-corrected visual acuity(BCVA),intraocular pressure(IOP),surgery complications and retinal redetachment were examined . RESULTS: The follow-up duration was 6 months to 12 months postoperatively,mean 9.2 months. BCVA of 17 eyes was more than 0.1. IOP of 2 eyes increased in short time after surgery. Retina was completely reattached in 30 eyes (94%).Subretinal proliferative membrane in 2 eyes which continued to worsen after scleral buckling were achieved by vitrectomy.CONCLUSION:Scleral buckling procedure without subretinal fluid drainage is a simple and efficient surgery for the treatment of old retinal detachment without seriously subretinal proliferative membrane.
