Abstract

Purpose: To report the estimated incidence, probability, risk factors, and 1-year outcomes of rhegmatogenous retinal detachment (RRD) in eyes receiving intravitreal injections (IVTs) of VEGF inhibitors for various retinal conditions in routine clinical practice. Design: Retrospective analysis of data from a prospectively designed observational outcomes registry: the Fight Retinal Blindness! project. Participants: Eyes of patients starting IVTs of VEGF inhibitors (ranibizumab, aflibercept, or bevacizumab) for neovascular age-related macular degeneration, diabetic macular edema, or retinal vein occlusion from January 1, 2006, to December 31, 2020. All eyes that developed RRD within 90 days of IVTs were defined as cases with RRD and were matched with control eyes. Methods: Estimated incidence, probability, and hazard ratios (HRs) of RRD were measured using Poisson regression, Kaplan–Meier survival curve, and Cox proportional hazards models. Locally weighted scatterplot smoothing curves were used to compare visual acuity (VA) between cases and matched controls. Main Outcome Measures: Estimated incidence of RRD. Results: We identified 16 915 eyes of 13 792 patients who collectively received 265 781 IVTs over 14 years. Thirty-six eyes were reported to develop RRD over the study period. The estimated incidence (95% confidence interval [CI]) per year per 1000 patients and per 10 000 injections was 0.77 (0.54–1.07) and 1.36 (0.95–1.89), respectively. The probability of RRD did not significantly increase at each successive injection (P = 0.95) with the time of follow-up. Older patients (HR [95% CI] = 1.81 [1.21–3.62] for every decade increase in age, P < 0.01) were at a higher risk of RRD, whereas patients with good presenting VA (HR [95% CI] = 0.85 [0.70–0.98] for every 10-letter increase in VA, P = 0.02) were at a lower risk. Neither the type of retinal disease (P = 0.52) nor the VEGF inhibitor (P = 0.09) was significantly associated with RRD risk. Cases with RRD lost 3 lines of vision on average compared with the prior RRD VA and had significantly fewer injections than matched controls over the year after the RRD. Conclusions: Rhegmatogenous retinal detachment is a rare complication of VEGF inhibitor IVT in routine clinical practice with poor visual outcomes at 1 year.
