To the Editor Vail et al1 conducted a cohort study of 38 144 patients with commercial insurance in the United States who had rhegmatogenous retinal detachment (RRD), using insurance claims from 2008 through 2016 to determine the association of management of RRD with the day of the week of diagnosis or repair. They found that patients were more likely to experience repair with pneumatic retinopexy (PR) when they received a diagnosis of RRD from Friday to Sunday, patients undergoing PR on a Sunday were more likely to require reoperation within 30 days, and those who received a diagnosis on a Friday waited longer for repair.1
