Research Article: Optical Coherence Tomography Angiography (OCTA) Differences in Vessel Perfusion Density and Flux Index of the Optic Nerve and Peri-Papillary Area in Healthy, Glaucoma Suspect and Glaucomatous Eyes
Introduction:
Glaucoma is a progressive optic neuropathy with an as yet poorly determined overall pathophysiology. The degeneration of retinal ganglion cells and their axons is thought to result in optic nerve damage and visual field loss. Glaucoma may also develop due to a vascular insufficiency of the optic nerve. Fluctuation of ocular blood flow and poor ocular perfusion in glaucoma patients were found to correlate with visual field perimetric deterioration and ocular hemodynamic instability, in agreement with ocular…
