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.
