ITT intent-to-treat set (all randomized subjects); PPS per-protocol set (subjects with complete data of primary and secondary target variables at the first and last visit, with no major protocol deviations); BCVA best corrected visual acuity;

Comparisons between groups were done using Student’s t-test for dependent samples. BCVA changes are expressed in ETDRS charts for better statistical analysis
