Summary

Cachectic patients and controls undergoing a comprehensive ophthalmologic examination. The imaging of all subjects is undertaken using a commercial OCTA device with a scan rate of 70,000 A-scans/s, scan beam wavelength of 840 ± 10 nm and bandwidth of 45 nm. All measurements are performed between 10:00 and 12:00 on the same day. The OCTA images are independently graded and assessed by two retinal specialists. The software automatically segmented these full-thickness retinal scans into the superficial and deep inner retinal vascular plexuses, outer retina, and choriocapillaris (CC). The vascular density in the superficial and deep retinal vascular zones is calculated automatically by the software, and the foveal avascular zone (FAZ) and foveal density (FD) are also automatically determined. Choroidal thickness is calculated manually by two retinal specialists, and the average value was used.
