Figure 6. Previous studies show that the central retina thickness (CRT) is larger in PCV patients treated with IVR compared to the patients given PDT. A: A meta-analysis demonstrates that treatment has a greater potential to keep the retina healthy than PDT 6 months after the treatments in patients with PCV. B: IVR has a significant advantage in the reduction of CRT (filled red squares) compared to PDT. Filled green circles are the average CRTs reported in the two studies.
