Clinical Use of Optical Coherence Tomography Angiography in Retinal Diseases.

The advent of optical coherence tomography angiography (OCTA) is one of the cornerstones of fundus imaging.

Although it has only recently come into clinical use, OCTA has become a non-invasive diagnostic tool for the diagnosis and follow-up of many retinal diseases, and the integration of OCTA in multimodal imaging has provided a better understanding of many retinal disorders.
