PURPOSE:
To examine the association between iris color, hair color, and skin sun sensitivity and the 10-year incidence of age-related maculopathy (ARM).
DESIGN:
Population-based cohort study.
PARTICIPANTS:
A population of 4926 adults (range, 43-86 years of age at baseline) living in Beaver Dam, Wisconsin, was studied at baseline (1988-1990); of these, 3684 and 2764 subjects, respectively, participated in 5-year and 10-year follow-up examinations.
METHODS:
Data on hair color at age 15 years and skin responsiveness to sun exposure were obtained from a standardized questionnaire administered at the baseline examination. Iris color was determined with penlight illumination during the baseline examination by using photographic standards. Age-related maculopathy status was determined by grading stereoscopic color fundus photos with the Wisconsin Age-Related Maculopathy Grading System.
MAIN OUTCOME MEASURES:
Incidence and progression of ARM.
RESULTS:
When controlling for age and gender, people with brown eyes were significantly more likely to develop soft indistinct drusen (risk ratio [RR], 1.53; 95% confidence interval [CI], 1.19-1.97; P < 0.01) than were people with blue eyes. However, people with brown eyes were significantly less likely to develop retinal pigment epithelial depigmentation (RR, 0.58; 95% CI, 0.41-0.82; P < 0.01) than were people with blue eyes. When compared with persons with blond hair, persons with brown hair were at decreased risk of developing pigmentary abnormalities (RR, 0.73; 95% CI, 0.53-1.00; P = 0.05). Iris color, hair color, and skin sun sensitivity were not associated with the development of late ARM.
CONCLUSION:
Iris color and hair color were found to be associated with the 10-year incidence of pigmentary abnormalities. Iris color seems to be inconsistently related to the 10-year incidence of early ARM lesions and the progression of ARM.
