VISUAL LOSS FROM NONARTERITIC ANTERIOR ISCH-emic optic neuropathy (NAION) has been reported after the use of phosphodiesterase (PDE)-5 inhibitors. 1–9 Those that argue a causal association cite a temporal relationship (half an hour to 36 hours) between the cause (taking the drug) and purported effect (NAION); a suggested mechanism of lowered blood pressure reducing the blood supply to the optic nerve; prior reports of visual symptoms (for example transient blue vision) as side effects of these drugs; and rare rechallenge cases. In response to a recent flurry of lay press coverage about the possible association of NAION and sildenafil (Viagra), the Food and Drug Administration (FDA) has approved new labeling for these drugs (including sildenafil,[vardenafil] Levitra, and [tadalafil] Cialis) to include information on NAION.According to the FDA Web site, 10 as of May 18, 2005, 43 cases of ION after the use of PDE-5 inhibitors had been reported to the FDA’s Adverse Event Reporting System. Of these 43 cases, 38 were sildenafil, four were tadalafil, and one was vardenafil. Most (25 of 43) were presumed to have had NAION. Thirty-six of the 43 cases had visual loss, and 26 of these 36 had “continuing or permanent” loss. A temporal relationship was proposed in 19 sildenafil cases, four tadalafil cases, and the one vardenafil case. Recurrent ocular symptoms were reported in five sildenafil cases and one tadalafil case.
