Optical Coherence Tomography Angiography is a new technique for non-invasive, dyeless angiography. It gives flow information of retinal and choroidal vasculature. It’s utility in diagnosing and monitoring various retino-choroidal vascular pathologies especially CNV (choroidal neovascular membranes) has been well established in a number of studies. A few clinical cases are discussed herein which highlight different aspects of OCT-A guided clinical management. It is of importance to understand the imaging characteristics and artifacts on OCT-A before adopting it as the primary angiographic modality. As always clinical correlation with history and other imaging modalities like OCT must be done before deciding ‘which vessels to treat’.
