I Thought It Was Self Gratification That Did It

Viagra may cause blindness:

WASHINGTON - Federal health officials are examining rare reports of blindness among some men using the impotence drug Viagra.

The Food and Drug Administration still is investigating, but has no evidence yet that the drug is to blame, said spokeswoman Susan Cruzan.

This type of blindness is called NAION, or non-arteritic anterior ischemic optic neuropathy. It can occur in men who are diabetic or have heart disease, the same conditions that can cause impotence and thus lead to Viagra use.
