    4. Predictors of neovascular activity during neovascular age-related macular degeneration treatment based on optical coherence tomography angiography

      Predictors of neovascular activity during neovascular age-related macular degeneration treatment based on optical coherence tomography angiography
      The advent of anti-vascular endothelial growth factor (VEGF) therapies has remarkably improved the functional outcomes of neovascular age-related macular degeneration (nAMD) patients. However, there are guidelines on how to start treatment, the guidelines for discontinuing treatment are not yet clear. In this respect, the treat-extend-stop (TES) protocol have showed us the possibility of discontinuing treatment.
