Summary:
Optical coherence tomography angiography is a modern method of diagnostics of macular diseases, which allows for the evaluation of flow in the vessels of the central part of the retina. Age-related macular degeneration is the most common disease with the presence of pathological vessels in the macular area. This diagnostic method helps detect abnormal vascularization, which proves the presence of an exudative form of the disease, as well as locate the layer of the retina and/or choroid in which vessels run. Fluorescein angiography, an examination with intravenous contrast, provides an indication of pathological vessel activity by finding leakage from the vascular network. Optical coherence tomography angiography also indicates the presence of pathological vessels, but a detailed evaluation of their activity may be difficult. The correct interpretation of the optical coherence tomography angiography result requires not only proving that pathologic vessels are visible, but also confirming that they are active.
This study presents the latest knowledge on specific lesions evident in optical coherence tomography angiography. They have predictive value for the evaluation of vascular activity and help follow the course of the disease and response to treatment.
