Key result
Corneal arcus fails to predict diastolic hypertension, myocardial infarction, or stroke.
Cross-Sectional
A survey of two populations of negroes and whites has revealed a higher frequency of corneal arcus in the negro. While both races show a tendency to develop the lesion with advancing age, some negro men and women will show lesions relatively early in life. The corneal lesion seems not to be a useful predictor of diastolic hypertension, myocardial infarction, or cerebrovascular accidents. It is suggested that in the negro at least, the development of arcus is genetically determined, rather than a reflection of a generalized lipid disturbance or of generalized vascular disease. It would appear desirable to label this lesion arcus corneae rather than arcus senilis or gerontoxon.

Macaraeg et al. (1968) conducted a cross-sectional in Corneal arcus, diastolic hypertension, myocardial infarction, and cerebrovascular accidents. Corneal arcus ( and race) vs. Absence of corneal arcus (and White population) was evaluated on Frequency of corneal arcus and prediction of diastolic hypertension, myocardial infarction, or cerebrovascular accidents. Corneal arcus occurred more frequently and earlier in Black than White individuals, and was not a useful predictor of diastolic hypertension, myocardial infarction, or cerebrovascular accidents.
