In view of the generally impair-ed vascular condition in patients with coro
nary artery disease (CAD), we were interested in the condition of their col
or perception. Color vision was examined by the cap-sorting test, Roth 28-h
ue desaturated. Twenty-four patients (m:f = 23:1, mean age 58 +/- 9 years)
with an angiographically documented coronary artery disease and 30 generall
y healthy controls (m:f = 29:1; mean age 54 +/- 7) were examined. Visual ac
uity, visual field, intraocular pressure, and the cup/disc ratio of the pat
ients were within normal range. However the results of the color vision tes
ting revealed a significantly higher error score in the group of patients w
ith CAD than in the control group (median +/- mean absolute deviation: 222
+/- 84; p < 0.001). In conclusion, although patients with coronary artery d
isease appeared ophthalmo-logically healthy under routine eye examination,
their color vision was disturbed This should be taken into account in color
-vision testing to avoid diagnostic inferences between specifically ocular
diseases (e.g., glaucoma) and atherosclerosis. (C) 2000 John Wiley & Sons,
