In this series, we discuss the role of optical coherence tomography angiography (OCTA) in assessing response to treatment in intraocular vascular tumors. This is a series of two cases: Multiple retinal capillary hemangioblastoma (RCH) treated with laser photocoagulation and diffuse choroidal hemangioma (DCH) with radiotherapy. In large RCH and DCH, optical coherence tomography (OCT) showed significant reduction of subretinal and intraretinal fluid. But post-treatment mean tumor vascular density (MTVD) was slightly reduced. In one small RCH, vascular loop was seen suggesting minimal residual disease. So, OCTA helps in identifying treatment inadequacy and understanding alternate mechanism involved in treatment response in vascular tumors.
