- Primary Outcome Measures
Name Time Method Number of Participants With Confirmed Diagnosis of Non-arteritic Anterior Ischemic Optic Neuropathy (NAION) Up to 45 days prior to study enrollment The study population consisted of adult men, first diagnosed with NAION which started within 45 days before study start and took PDE5 inhibitors (vardenafil, sildenafil, tadalafil or avanafil) in the 1 year prior to enrollment.
- Secondary Outcome Measures
Name Time Method Number of Participants With Most Frequent Medical History Findings by Primary System Organ Class at Visit 1 Day 1 The safety population includes participants who signed informed consent and who had any of the following collected at Visit 1 for safety: laboratory values, physical exam, any eye exams, or adverse events.
Number of Participants With Any Adverse Events Reported at Visit 2 From informed consent signed up to Visit 2 (Day 90+/-30) An adverse event is any untoward medical occurrence in a subject or clinical investigation subject and can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally occurring during the trial.
