Optical Coherence Tomography Angiography: A Window into Central Nervous System Neurodegeneration.

Optical coherence tomography angiography (OCT-A) allows noninvasive visualization of intraocular tissues with high resolution. Recently, an innovative use of this technology in studying neurodegenerative diseases has emerged with the neurosensory retina as a unique window into deeper brain tissues. Here, we discuss its role in identifying biomarkers of neurodegenerative diseases. [ABSTRACT FROM AUTHOR]
