Summary
Pediatric optic neuritis (ON) outcomes show significant visual acuity improvement within 6 months, maintained over two years. However, associated autoimmune diagnoses are common, with 18% experiencing additional ON episodes.
Area of Science:
- Ophthalmology
- Neurology
- Pediatrics
Background:
- Pediatric optic neuritis (ON) is a rare condition lacking comprehensive characterization.
- The Pediatric ON Prospective Outcomes Study (PON1) was initiated to address this knowledge gap.
Purpose of the Study:
- To evaluate visual acuity (VA) outcomes in children with ON.
- To assess recurrence risk and final diagnoses 2 years post-enrollment.
Main Methods:
- A nonrandomized observational study conducted across 23 pediatric ophthalmology/neuro-ophthalmology clinics.
- 28 children (age 3-15) completed the 2-year follow-up.
- Treatment was at the investigator's discretion.
Main Results:
- Most children achieved age-normal high-contrast VA (79%) and 20/20 or better vision (66%) by 2 years.
- Final diagnoses included isolated ON (39%), MOG-AD (29%), MS (14%), NMOSD (11%), and ADEM (7%).
- Recurrent ON occurred in 7% (all MS), and 7% had new episodes in the unaffected eye.
Conclusions:
- Children with ON show substantial VA improvement by 6 months, sustained over 2 years.
- Neurologic autoimmune diagnoses are frequently associated with pediatric ON.
- 18% of participants experienced additional ON episodes (relapses or new eye involvement).
