Long, Middle, and Short- CCT scores (i.e., Red, Green, and Blue CCT scores) for the cognitive impairment group.

Rabin CCT scores	Cognitive Impairment Cases n = 20 Mean (SD)	Cognitively Healthy Cases n = 19 Mean (SD)	p-value
L-CCT (red)	56 (12)	91 (8)	<0.001∗∗
M-CCT (green)	47 (18)	89 (8)	<0.001∗∗
S-CCT (blue)	63 (12)	91 (7)	<0.001∗∗

CCT scores of 75 or greater are defined as normal (Rabin et al., 2011). The visual performance test with the computerized CCT, revealed functional loss in color vision. The P-values were calculated by an independent sample t-test. ^∗∗Significant (p < 0.01).
