Risk Factors of Hyphema following Surgeries for Primary Rhegmatogenous Retinal Detachment

摘要

Purpose: This study aimed to evaluate the risk factors for hyphema complicating primary rhegmatogenous retinal detachment (RRD) surgeries and to analyze outcomes. Methods: In this retrospective comparative study, we included 1,011 consecutive eyes. Two groups were compared according to the occurrence of postoperative hyphema. Results: Postoperative hyphema occurred in 32 eyes (3.17%). High myopia was significantly related to the occurrence of hyphema (odds ratio [OR] 3.396, 95% confidence interval [CI] 1.502-7.675; p = 0.003). Combined scleral buckling and vitrectomy (SB + VT) was associated with a significantly higher incidence of hyphema (OR 21.266, 95% CI 4.855-93.152; p < 0.001). The final anatomical success rate did not differ significantly between the group with and the group without occurrence of hyphema; however, the primary anatomical success rate was worse in the eyes with hyphema. Conclusions: High myopia and combined SB + VT were risk factors for hyphema after RRD surgeries. The occurrence of hyphema did not affect the final anatomical success rate at 6 months. (C) 2016 S.
