OCT Angiography: A promising tool in Glaucoma

Abstract

Optical Coherence Tomography Angiography, a non-invasive imaging modality provides a quantitative assessment of microcirculation of retina and choroid in various layers. It is based on split spectrum amplitude decorrelation algorithm (SSADA) which detects moving red blood cells and eliminates other noise (information). This review provides a comprehensive summary on relevance, uses and limitations of Optical Coherence Tomography Angiography (OCTA) in glaucoma.
