Figure 3. Four studies evaluated the visual acuity in a 6-month follow-up after the treatments. A: A meta-analysis indicates that IVR improved LogMar visual acuity compared to PDT 6 months after the treatments in patients with PCV. B: IVR has a significant advantage in the improvement of LogMar visual acuity (filled red squares) compared to PDT. Filled green circles are the average LogMar visual acuities reported in the four studies.
