No Evidence for Retinal Damage Evolving from Reduced Retinal Blood Flow in Carotid Artery Disease

Table 3

Side-to-side differences (no-CAD versus CAS/CAO) of OCT and functional measurements with no significant findings. RNFL: peripapillary retinal nerve fiber layer; G: global; S: superior; N: nasal; I: inferior; T: temporal; TMV: total macula volume; GCIPL: ganglion cell/inner plexiform layer; ONHV: optic nerve head volume; HCVA: high-contrast visual acuity; LCVA: low-contrast visual acuity (photopic = 85 cd/m², mesopic = 3 cd/m²); CAD: carotid artery disease; CAS: carotid artery stenosis; CAO: carotid artery occlusion, ± standard deviation. Paired sample Wilcoxon sign rank test was used for intereye comparisons (no-CAD versus CAS/CAO).
