Minimally invasive scleral buckling surgery under operating microscope for the treatment of rhegmatogenous retinal detachment

Abstract

Objective To evaluate the efficacy of minimally invasive scleral buckling surgery under operating microscope for the treatment of rhegmatogenous retinal detachment (RRD). Methods The data of 74 eyes of 72 patients with RRD from Dec. 2015 to Jun. 2017 were analyzed retrospectively. All cases were treated with minimally invasive scleral buckling under operating microscope. The operation time, postoperative reattachment, ocular surface recovery and complications were observed. Results The average duration of surgery was (26.7±20.2) min. One week after surgery, 68 eyes gained retinal reattachment; subretinal fluid was not absorbed at 3 days after surgery in 3 eyes and they received air tamponade. The retina was successfully reattached in 2 eyes and 1 eye received air tamponade again. One eye with large retinal tear gained retinal reattachment after vitrectomy. During the follow-up period, there were 2 eyes with new retinal redetachment. All retina were reattached after second surgery. The BCVA (LogMAR) was mean 1.32±0.37 before surgery, and BCVA at the last follow-up was 0.12±0.16. The difference was significant between after and before operation (t=16.52, P<0.001). Conclusion Minimally invasive scleral buckling surgery under operating microscope is a safe and efficient surgical method.
