Optic Nerve Damage Linked to Viagra, Cialis
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.
The condition is the most common cause of acute optic nerve disease in
people older than 50, and can cause permanent vision loss in one or
both eyes.
