Birth control mix up

New research suggests that women who use birth control for extended periods of time may be risking their eyesight.

A study by the University of California-SF, Duke University and Nanchang University analyzed date from over 3,000 women over the age of 40.

Those who had used any type of oral contraception for longer than three years were twice as likely to be diagnosed with glaucoma.

Researchers say this doesn’t mean the pill causes glaucoma but long-term use could be a risk factor.

They also found that patients had a greater chance of being diagnosed with the disease if they were African-American, had a family history and existing visual problems.

Although more studies are needed, experts advise women who have taken the pill for a long period of time to be screened for glaucoma, especially if they have other risk factors.

The research was presented at a meeting and has not undergone extensive peer review.
