VEGFA and hydrops fetalis: Although there was a slight decrease in the number of eyes with more than 30 HF after three doses of anti-VEGF treatment, it was not statistically significant (p = 0.227); however, at the sixth-month and 12th-month visits, OCT images revealed a statistically significant decrease in the percentage of more than 30 HF compared to baseline (p = 0.002, p < 0.001) (Figure 3a).
