Summary
Older age, male sex, and worse initial visual acuity predict poorer outcomes in acute optic neuritis. These factors help identify patients at risk for worse visual function 6 months post-episode.
Area of Science:
- Ophthalmology and Neuroscience
- Clinical Neuroimmunology
Background:
- Acute optic neuritis (ON) is a common cause of visual loss in young adults.
- Predicting visual outcomes in ON is crucial for patient management and clinical trial design.
Purpose of the Study:
- To identify baseline clinical predictors of visual outcomes 6 months after acute optic neuritis.
- Utilized data from the Treatment of Optic Neuritis with Erythropoietin (TONE) clinical neuroprotection trial.
Main Methods:
- Secondary analysis of 103 patients with a first episode of acute unilateral ON.
- Assessed predictors of high-contrast visual acuity (HCVA), low-contrast acuity, VEP P100, and retinal layer thickness at 6 months.
- Employed multiple regression analysis on pooled, treatment-agnostic data.
Main Results:
- Higher baseline HCVA predicted better outcomes across most measures.
- Male sex predicted worse outcomes for most measures, except HCVA.
- Older age was associated with poorer functional outcomes.
Conclusions:
- Older age, male sex, and worse initial visual function are associated with poorer outcomes in acute optic neuritis.
- These predictors can inform patient counseling and clinical trial participant selection.
- Findings aid in balancing risk characteristics in neuroprotection trials for optic neuritis.
