The image outlines the regions of interest for measuring retinal layer thickness on enhanced depth imaging optical coherence tomography (EDI-OCT) scans of an eye with central retinal artery occlusion (CRAO). These measurements were manually conducted using OCT software. Central foveal thickness (CFT) and central choroid thickness (CCT) were assessed, with CFT representing the distance between the inner retinal surface and the outer border of the retinal pigment epithelium (RPE) at the central fovea, and CCT indicating the space between the outer portion of the hyperreflective line corresponding to the RPE layer and the chorioscleral junction. The inner retinal layer (IRL) includes the ganglion cell layer, inner plexiform layer, inner nuclear layer, and outer plexiform layer, while the outer retinal layer (ORL) comprises the remaining layers until the RPE. Thickness measurements of ORL and IRL were conducted 1000 Ī¼m temporal to the fovea.
