Figure 1. Mean change in best-corrected visual acuity (BCVA) from baseline to month 9. Intravitreal triamcinolone acetonide (TA) injections were administered at month 6 after at least three consecutive intravitreal conbercept (IVC) injections. Data are expressed as mean ± standard deviation (SD). Wilcoxon matched-pairs test with Bonferroni corrections were used to compare the significance of the changes between baseline and each time point. *p <0.001 relative to the baseline of the BCVA.
