    Optical coherence tomography angiography markers associated with treatment response in neovascular age-related macular degeneration

    Purpose: To investigate whether qualitative and quantitative features of choroidal neovascular membranes are associated with anti-vascular endothelial growth factor treatment response in patients with neovascular age-related macular degeneration. Methods: A total of 41 eyes were included in this cross-sectional observational study and divided into “good responders” and “poor responders” based on the long-term functional changes, frequency of recurrent choroidal neovascular activity, and injection need. Enface optical coherence tomography angiography images were obtained and qualitative features of choroidal neovascular membranes were described based on vessel network density. Then, quantitative measurements including vessel area, vessel length, junction density, and lacunarity were calculated ...
