Researchers in the Department of Ophthalmology and Visual Sciences at the University of Wisconsin have found that risk factors for cardiovascular disease such as smoking and higher body mass index are also risk factors for age-related macular degeneration (AMD).
 
The subjects in this study were 4,288 women age 63 years and older who were participating in the Women’s Health Initiative Sight Examination (WHISE).  Using a standardized questionnaire and examinations, researchers obtained information from the women on cardiovascular disease and its risk factors.  

919 of the women in the study were diagnosed with AMD (determined by standardized grading of fundus photographs).

The results were straightforward:  women who were identified as having four important risk factors for cardiovascular disease were also significantly more likely to have AMD.  These risk factors were:

• smoking
• use of calcium channel blockers
• diabetes, and
• greater body mass index.
