Purpose: To evaluate the risk factors for the development of concurrent or delayed-onset rhegmatogenous retinal detachment (RRD) related to endophthalmitis as well as the anatomic and visual outcomes with subsequent RRD repair. Methods: In this retrospective case study, a 2-tailed t test (continuous) and Fisher exact test were used to determine statistical significance of the observed findings. The relative risk (RR) and 95% CIs were calculated to assess statistical significance. Results: Of the 170 patients included, 22 were found to have a concurrent or subsequent RRD. Initial treatment with pars plana vitrectomy (PPV) (RR, 3.544; 95% CI, 1.650-7.614), aphakia (RR, 4.150; 95% CI, 1.434-12.011), endogenous endophthalmitis (RR, 2.684; 95% CI, 1.065-6.764), and posterior synechiae (RR, 3.026; 95% CI, 1.408-6.505) were statistically significant risk factors for RRD. Anatomically successful repair was achieved in 77.7% of patients. Conclusions: In addition to preexisting risk factors, the initial treatment of endophthalmitis may be a significant risk factor for RRD development, with a higher incidence of subsequent RRD in patients who have PPV as the initial treatment for endophthalmitis.
