Statistical analysis of the reduction in vessel amount in choroidal layer in response to treatment. (a) The numbers of counted vessels inside the treated area before and 4 weeks after the PUT treatment for all the six cases. Error bars (median ± standard error) were calculated based on three fundus pictures for each eye at the same time point. (b) Normalized vessel amount reduction of the PUT group. (c) The numbers of counted vessels inside the treated area before and 4 weeks after the treatment using either laser only or ultrasound only (i.e., control groups). Error bars (median ± standard error) were calculated based on three fundus pictures for each eye at the same time point. (d) Normalized vessel amount reduction of the control group. (e) Percentile reduction in vessel amount in response to different treatments (i.e., PUT, laser only, and ultrasound only). *** stands for p < 0.01.
