Trends in the clinical presentation of primary rhegmatogenous retinal detachments during the first year of the COVID-19 pandemic.

Abstract Purpose To evaluate the effect of one full year of the coronavirus disease 2019 (COVID-19) pandemic on clinical presentation of acute, primary rhegmatogenous retinal detachment (RRD). Design Single-center, retrospective observational cohort study. Methods Patients were divided into two cohorts; consecutive patients treated for primary RRD during the COVID-19 pandemic (March 9, 2020 to March 7, 2021; pandemic cohort) and patients treated during the corresponding time in previous year (March 11, 2019 to March 8, 2020; control cohort). Main outcome measures Proportion of patients presenting with macula-involving (mac-off) or macula-sparring (mac-on) RRD. Results 952 patients in the pandemic cohort and 872 patients in the control cohort were included. Demographic factors were similar. Compared to the control cohort, significantly greater number of pandemic cohort patients presented with mac-off RRDs ([60.92%] pandemic, [48.17%] control, P = 0.0001) and primary proliferative vitreoretinopathy (PVR; [15.53%] pandemic, [6.9%] control, P = 0.0001). Pandemic cohort patients (10.81%) had significantly higher rates of lost to follow-up compared to control cohort (4.43%; P = 0.0001). Patients new to our clinic demonstrated significant increase in mac-off RRDs in the pandemic cohort (65.35%) compared to control cohort (50.40%; P = 0.0001). Pandemic cohort patients showed worse median final best-corrected visual acuity (BCVA; 0.30 logarithm of the minimum angle of resolution [logMAR]) compared to control cohort (0.18 logMAR; P = 0.0001). Conclusions Patients with primary RRD during the first year of the COVID-19 pandemic were more likely to have mac-off disease, present with primary PVR, be lost to follow-up, and have worse final BCVA outcomes.
