Study: Birth control may be linked to glaucoma

Posted: Updated:

New research suggests long-term use of oral contraceptives could increase a woman's risk of developing glaucoma, a serious eye disease, according to NBC News.

The study analyzed data from more than 3,000 women over the age of 40.

Those who had used any type of oral contraceptives for longer than three years were twice as likely to be diagnosed with glaucoma, which is a leading cause of blindness.

Researchers stress that this does not mean the pill causes glaucoma, but that long-term use could be a risk factor. Other risk factors include a family history, existing visual problems and African-American ethnicity.

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 as well.

The research was presented at a meeting, and has not yet gone through an extensive peer review process.
