Fig. 2. Comparison of coronary computed tomographic angiography findings between RAO patients and control groups. (A) Obstructive CAD was significantly common in RAO patients compared to control subjects. (B) Mean coronary artery calcium score of RAO patients was significantly higher than that of control subjects. (C) Both SIS and SSS were significantly higher in RAO patients compared to control subjects. (D) The number of segments with calcified or mixed plaques were not significantly different; however, the number of non-calcified plaques was significantly higher in RAO patients.

RAO = retinal artery occlusion, CAD = coronary artery disease, DS = diameter stenosis, CACS = coronary artery calcium score, SIS = segment-involvement score, SSS = segment-stenosis score, CAP = coronary artery plaque.

^*Statistically significant difference, P value < 0.05.
