Initial Dose of Three Monthly Intravitreal Injections versus PRN Intravitreal Injections of Bevacizumab for Macular Edema Secondary to Branch Retinal Vein Occlusion

Figure 3

Mean central retinal thickness (CRT) change from baseline over time to 12 months after the initial bevacizumab injection. There is no significant difference in CRT change between the 2 treatment schedules at any visit. Only at month 3, CRT change showed a marginally significant difference between the 2 groups. Error bars denote upper or lower bound of 95% confidence intervals. Statistical analyses were performed using Student’s 𝑡-tests. The numbers on the right side of the arrow indicate the numbers of patients who were retreated with intravitreal bevacizumab injection at that time.
