Viagra is responsible for more cases of ischemic optic neuropathy than any other drug. Viagra and Cialis are responsible for other eye problems, such as blindness.

I would like the FDA to require a black box warning on such drugs and create a registry of patients who develop eye problems due to such drugs. The public needs explicit warning regarding the risks of taking such drugs.
