aSignificant difference in BCVA between affected eyes and unaffected eyes in ischemic BRVO group according to Kruskal-Wallis test (P<0.05). Except that, no significant difference in other aspects found between ischemic BRVO group and non-ischemic BRVO group. Corresponding control A and control B showed no significant difference in gender and age. BCVA: Best corrected visual acuity; CME: Cystoid macular edema.
