The aim of this study is to present the most important rules for the correct interpretation of optical coherence tomography angiography and to describe the most important artifacts. Optical coherence tomography angiography is a frequently performed examination in retinal and choroidal diseases. The main advantage is the non-invasive imaging of blood vessels. In order to correctly interpret the results, different rules should be followed than in dye angiography. Importantly, artifacts of various kinds may occur, resulting from poor signal strength, motion, projection, or incorrect segmentation. Despite its various limitations, optical coherence tomography angiography is a very useful method in diagnosis, monitoring and responding to the treatment; it also facilitates our understanding of the pathogenesis of many diseases.
