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.
Small choroidal melanoma tumor thickness was overestimated by 55% on ultrasonography compared with EDI-OCT. The EDI-OCT features of small choroidal melanoma compared with choroidal nevus include increased tumor thickness, subretinal fluid, subretinal lipofuscin deposition, and retinal irregularities, including shaggy photoreceptors.
While measurements taken with the same machine and technique are consistent and reliable between fellow eyes, significant variability exists in FAZ and capillary density measurements among different machines and techniques. Comparison of measurements across machines and techniques should be considered with caution.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
