  1. CRT central retinal thickness, PED pigment epithelium detachment, CV choroidal volume; Multivariate analysis adjusted for age, sex and number of injections. Bold fonts denotes parameters significantly influencing the gain in BCVA and disease activity at month 12 from baseline and are retained in the final multivariable model.
