Hypertensive retinopathy in Nigerians. A prospective clinical study of 350 cases.

Abstract

In a prospective study of retinal changes in 350 hypertensive Nigerians from two institutions, over 70% of the patients showed hypertensive retinopathy. This is in agreement with the findings of some other studies in Africans. There was a statistically significant correlation between the height of blood pressure and severity of retinal changes. There was also a significant correlation between age and the early retinal changes but there was no environmental influence on the percentage distribution of retinopathy between the two institutions studied.
