Efficacy of vitrectomy combined with scleral buckling for rhegmatogenous retinal detachment with vitreous hemorrhage

Objective To evaluate the efficacy of pars plana vitrectomy (PPV) combined with minimal segmental scleral buckling (MSSB) without inert gas or silicone oil tamponade for the treatment of rhegmatogenous retinal detachment (RRD) with vitreous hemorrhage. Methods The data of 99 eyes of 99 cases with RRD with vitreous hemorrhage underwent PPV combined with MSSB from Mar. 2010 to May 2015 were collected and analyzed retrospectively. Results All eyes were localized no-proliferative RRD including 67 eyes with trauma history. The tears placed peripheral retina within a quadrant. Retinal tears were inferior in 73 eyes(73.74%). During operation, 21 eyes (21.21%) underwent air tamponade and 78 eyes (78.79%) received perfusate tamponade. The retinal reattachment rate of the first surgery was 92.93%. The final retinal reattachment rate was 100.00%. The postoperative visual acuity was improved (χ2=68.561, P=0.000). At the end of follow-up, the mean IOP increased from (14.55±3.81) mmHg (1 mmHg=0.133 kPa) to (17.92±2.45) mmHg (t=4.315, P=0.000). However, the IOP were in the normal range. No severe complication occurred during or after surgery. Conclusion PPV combined with MSSB without inert gas or silicone oil tamponade for the treatment of RRD with vitreous hemorrhage has high retinal reattachment rate and few complications.
