Senile macular degeneration and risk factors: a case-control study

Abstract

A case-control study of patients ranging in age from 52 to 88 years was done to determine any possible relationship between health factors and senile macular degeneration. Thirty cases and 30 controls were pair-matched according to age, sex, and race. Chart reviews and telephone interviews were the methods of data collection used. The patients were interviewed concerning a history of vascular disease and other health characteristics. The data were analyzed by a paired-sample method. The results of the study showed a definite relationship with age and sex. Moreover, a significant relationship between refractive error and senile macular degeneration was noted. Such an association has not been previously reported. No relationship was found between vascular disease and senile macular degeneration.
