Purpose: To characterize how community mobility patterns across the United States correlate with local changes in retina visits during the pandemic. Methods: Outpatient retina clinic visits were linked to population mobility by combining multiple public data sets, including the Google Community Mobility Reports and data from the Centers for Disease Control and Infection. Percentage change from baseline in daily-average number of retina visits by county and mobility were measured by county. Results: A total of 2,159,689 patient visits were examined across 332 counties. Daily-average retina visits decreased by 7.0%, 19.0%, 5.0%, and 4.0% from Quarter 1 to 4 of 2020. This decrease was negatively correlated with increased incident of COVID-19 deaths for Quarters 1 to 3 (r = -0.13, r = -0.16, and r = -0.15, respectively, P < 0.001) and increased incident cases for Quarters 1 and 2 (r = -0.18, r = -0.13, respectively, P < 0.001). Daily-average retina visits relative to baseline were significantly lower for metropolitan counties in Quarters 1 and 2, compared with urban and rural (P < 0.001). The decline in retina visits had greatest association with decline in workplace visits in Quarters 1 to 3 (r = 0.27, r = 0.09, r = 0.12, respectively, P < 0.001 for all). Conclusion: This study provides insight into how regional mobility patterns may help to explain and predict patient behaviors and retina outpatient visit responses during the COVID-19 pandemic.
