OCTA is a valuable non-invasive tool that can detect subclinical neovascularization. On follow up, a significant proportion of these lesions start to develop exudation and require treatment. Although structural OCT remains the gold standard for assessing treatment need, changes in the OCTA may enlighten us on the processes leading to exudation. Longitudinal changes observed include enlargement of lesion, increase in branching pattern of vascular network as well as development of new aneurysmal lesions.
