Results

Figure 1 Comparison of mean±SD values of BCVA between measurements at baseline and measurements obtained during follow ± up among different doses groups．m ＝ month．

Figure 2 Comparison of mean±SD values of central foveal thickness between measurements at baseline and measurements obtained during follow±up among different doses groups by optical coherence tomography．m ＝ month．

Figure 3 Kaplan±Meier survival plots of eyes requiring reinjection of TA after the planned 12±month follow±up among three different doses groups．The survival curve in the 16 mg group was significantly better than that in the 4mg group．

Figure 4 IOP measurements at before （Baseline） and monthly intervals after IVTA injection for 6-10 months were recorded （mean±SD）．The highest IOP was measured at 3 months in the 4 ／8mg groups， 2-3 months and 5-6 months in the 16mg group， respectively．The duration of TA-induced ocular hypertension was 3-4 months longer in the 4mg group，5-6 months in the 8mg group，7-9 months in the 16mg group， respectively．m＝month．
