NAION is the most common optic nerve disease that occurs in adults over the age of 50. In response to the possible link between NAION and medication like Viagra, Pfizer has stated: “Most of the cases in which NAION has occurred in men taking Viagra have involved patients with underlying anatomic or vascular risk factors associated with the development of NAION.” Essentially, this means that relationship between Viagra and NAION cannot be determined at this time.
“The bottom line is, and what I tell all my patients, is that these medication should never be taken unless they are needed because there are serious health and visual risks associated with them,” says Dr. Lewis.
