Type 1 Choroidal Neovascularization Evolution by Optical Coherence Tomography Angiography: Long-Term Follow-Up

Figure 7

Drawing of the CNV evolution after multiple treatments. Before treatment (a), the CNV has a greater proportion of small branching vessels and peripheral arcades, indicating an active lesion. After treatment (b), the same main vessels appear to return with increased flow and decreased branch density (vessels in red). Some main branches are less affected by the treatment (vessels in black). After several anti-VEGF treatments, the CNV shows fewer complex features. This morphological pattern corresponds to the “maturation pattern” of treatment (c).
