Case report: association of combined nonarteritic anterior ischemic optic neuropathy (NAION) and obstruction of cilioretinal artery with overdose of Viagra.
OBJECTIVE
We report on a case of combined nonarteritic anterior ischemic optic neuropathy (NAAION) and cilioretinal artery occlusion resulting from misuse of sildenafil citrate (Viagra Pfizer Pharmaceuticals, New York, NY).


METHODS
This is an observational case report.


METHODS
A 54-year-old white man developed blindness in his left eye after an overdose of Viagra. He was examined and fully evaluated.


RESULTS
Ocular examinations revealed a left relative afferent pupillary defect and a left combined NAAION and obstruction of the ipsilateral cilioretinal artery.


CONCLUSIONS
Although ocular side-effects of Viagra are rare, they are potentially blinding. Patients should be warned about the side-effects and against misuse of this agent.
