Descriptive Information
Brief Title A Study to Assess Whether PDE5 Inhibitors Increase the Chance of Triggering the Onset of Acute NAION
Official Title Case Crossover Study of PDE5 Inhibitor Exposure as a Potential "Trigger Factor" for Acute NAION
Brief Summary The objective of this non-interventional study is to examine whether use of Phosphodiesterase Inhibitors (PDE5s), including use of sildenafil, vardenafil, or tadalafil, triggers the onset of acute NAION.
Detailed Description Sites will identify patients who meet the entry criteria during the conduct of their normal practice. Patients meeting these criteria will be offered participation in the study after reading and completing an informed consent document.
Study Type Observational
Study Design Observational Model: Case-Crossover
Time Perspective: Retrospective
