Vision Restoration Therapy (VRT) to Treat Non-Arteritic Anterior Ischemic Optic Neuropathy
Completed · Not applicable
Conditions studied: Non-Arteritic Anterior Ischemic Optic Neuropathy
In brief
The goal of this pilot study is to evaluate the effect of Vision Restoration Therapy, VRT, on the visual function of patients with unilateral or bilateral AION, who have good central vision (at least 20/60) and altitudinal visual field defects.

Who can join
Age: 30 and older. Sex: any. Healthy volunteers: not accepted.
You may qualify if…
- Patients seen by Dr Biousse or Dr Newman in the Neuro-Ophthalmology Unit at Emory University.
- Age ≥ 30 years.
- Diagnosis of non-arteritic ischemic optic neuropathy at least 6 months prior to inclusion.
- Uni- or bilateral AION (in case of bilateral AION, only one eye will be included in the study).
- Best corrected visual acuity of at least 20/60 in the study eye
- Altitudinal or arcuate visual field defect, splitting fixation by >10 decibel difference above and below horizontal meridian.
- Stable visual function demonstrated by more than two stable visual acuity measurements and two automated visual field testings prior to inclusion in the study.
- Patient willing, and able, to spend 60 minutes-a-day for 6 months working on a computer.
You may not qualify if…
- Patient cognitively or physically unable to perform reliable automated perimetry testing (on the 24-2 SITA Standard program) (which is grossly equivalent to the effort and attention needed to perform VRT daily at home).
- Other cause of optic neuropathy.
- Associated ocular disease requiring treatments or responsible for visual loss (such as untreated significant cataract, glaucoma, age related macular degeneration, etc…).
- Visual acuity worse than 20/60 in the study eye.
- Non-stable visual field defect on previous evaluations.
- Epilepsy.
