A Study to Determine if There is a Possible Association Between Nonarteritic Anterior Ischemic Optic Neuropathy (NAION) and Phosphodiesterase Type 5 (PDE5) Inhibitors
Study H6D-MC-LVHQ is an observational, non-interventional, multi-center, prospective, case-crossover study to evaluate the possible association between the use of phosphodiesterase type 5 (PDE5) inhibitors and the risk of acute nonarteritic anterior ischemic optic neuropathy (NAION) in males. Subjects with newly diagnosed NAION will be asked via a structured questionnaire about their use of PDE5 inhibitors and other risk factors prior to the onset of their vision loss.
