Values are presented as mean ± standard deviation. Group A refers to the dexamethasone implant injection arm. Group B refers to the bevacizumab to dexamethasone implant injection arm.

Group C refers to the bevacizumab injection arm.

BCVA = best-corrected visual acuity; logMAR = logarithm of minimal angle of resolution; CMT = central macular thickness; IOP = intraocular pressure.
