You may be eligible for this study if you meet the following criteria:

  • Conditions: Nonarteritic Anterior Ischemic Optic Neuropathy
  • Age: Between 50 - 100 Years
  • Gender: Male or Female

Inclusion Criteria:

  • The participant must be 50 years of age or older at the time of the NAION episode in the study eye.
  • The participant has a definitive clinical diagnosis of NAION in the study eye that developed at least 12 months before randomization.
  • The participant's study eye must have stable visual acuity.
  • Using the study eye, the participant must read at least 20 and at most 66 EVA letters with best-corrected vision.
  • The participant's study eye must have a HVF 24-2 Swedish Interactive Testing Algorithm (SITA) Standard visual field using spot size III with mean deviation -5 dB or worse and with a visual field defect compatible with NAION in the study eye.

Exclusion Criteria:

  • The participant has had treatment with drugs that have potential neuroprotective or toxic effects on the optic nerve or retina (e.g., ethambutol, amiodarone, linezolid, hydroxychloroquine, fingolimod, brimonidine) within 6 months prior to enrollment.

  • The participant has systemic inflammatory or infectious disease associated with optic neuropathy or ocular disease.
  • The participant has a history of uveitis in the study eye within the last 10 years.
  • The participant's study eye has an ocular condition that appears consistent with a reduction in visual acuity to <20/25, diabetic retinopathy beyond mild non-proliferative diabetic retinopathy not involving the macula, or vision-threatening macula disease.
  • The participant has a visual field defect with homonymous non-altitudinal features or a defect that respects the vertical meridian.
