Impotence drugs such as Viagra and Cialis can increase the risk of eye damage in men who have a history of heart disease or high blood pressure, researchers reported Tuesday in the British Journal of Ophthalmology.
In a small study, scientists at the University of Alabama in Birmingham found that men who had suffered a heart attack were 10 times more likely to have a form of optic nerve damage called nonarteritic anterior ischemic optic neuropathy if they had been taking anti-impotence pills.
