Optical Coherence Tomography Angiography in Retinal Diseases

Optical coherence tomography angiography (OCTA) is a new imaging method providing the assessment of retinal and choroidal vasculature without a contrast agent. In this angiography type, the vascular networks have been visualized in detail though detecting motion contrast of erythrocytes in the vessel, using serial optical coherence tomography B-scans. Currently, OCTA findings of many retinal diseases have been reported.
