Viagra and Blindness

You knew the good times had to end -- the BBC reports on a University of Minnesota Medical School study that links use of viagra to vision loss.  According to the BBC report,

[Researchers at the University of Minnesota Medical School] writing in the Journal of Neuro-ophthalmology,said it brought the total number of reported cases to 14.

The seven men, aged between 50 and 69 years old, had all suffered from a swelling of the optic nerve within 36 hours of taking Viagra for erectile dysfunction.

I wonder whether information about potential vision loss was available to Pfizer when it requested FDA approval of its drug.  [bm
