Vision Restoration Therapy (VRT) to Treat Non-Arteritic Anterior Ischemic Optic Neuropathy
Non-Arteritic Anterior Ischemic Optic Neuropathy
About this trial
This is an interventional treatment trial for Non-Arteritic Anterior Ischemic Optic Neuropathy focused on measuring Non-Arteritic Anterior Ischemic Optic Neuropathy, Visual Field Defect, Neuroplasticity, Rehabilitation
Eligibility Criteria
Inclusion Criteria: 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. Exclusion Criteria: 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.
