Risk Factors of Hyphema following Surgeries for Primary Rhegmatogenous Retinal Detachment.

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.
