Correlation of Foveal Avascular Zone Size With Foveal Morphology in Normal Eyes Using Optical Coherence Tomography Angiography

Optical coherence tomography angiography provides a noninvasive method to visualize and measure the superficial and deep plexus FAZ in a normal population. The FAZ can vary in size and shape, with the FAZ area significantly larger in the deep compared with the superficial plexus. Both superficial and deep FAZ area correlate inversely with foveal thickness and volume.
