Insights

Pediatric acquired demyelinating disorders in Chinese children often present earlier and affect both eyes. Neuromyelitis optica spectrum disorder patients had worse vision and thinner retinal nerve fiber layers but improved with methylprednisolone.

Area of Science:

  • Neurology
  • Ophthalmology
  • Immunology

Background:

  • Pediatric acquired demyelinating disorders (ADS) encompass inflammatory central nervous system (CNS) conditions.
  • Optic neuritis (ON) is a key ADS manifestation involving autoimmune inflammation of optic nerve axons.

Purpose of the Study:

  • To investigate clinical characteristics, ophthalmic findings, laboratory results, and prognostic factors in Chinese pediatric ADS patients.
  • To analyze demographic data, visual acuity, antibody serostatus, and treatment outcomes.

Main Methods:

  • Retrospective analysis of clinical data from 57 pediatric ADS patients (March 2021-December 2023).
  • Evaluated best-corrected visual acuity (BCVA), peripapillary retinal nerve fiber layer (RNFL) thickness, and serum MOG/AQP4 antibody levels.
  • Assessed outcomes after intravenous methylprednisolone therapy.

Main Results:

  • The study included 38 ON, 12 NMOSD, 5 ADEM, and 2 MS patients; median ON onset age was 9 years, with 40.4% ≤8 years and 64.9% bilateral involvement.
  • MOG-antibody positivity was 50%, and AQP4-antibody positivity was 19.4%.
  • NMOSD patients showed significantly worse visual acuity (84.2% low vision) and thinner RNFL compared to ON patients (p < 0.05).
  • Affected eyes had thinner RNFL than unaffected eyes (median 72.0 μm vs. 102.0 μm, p < 0.05).
  • Both ON and NMOSD groups demonstrated good visual recovery (BCVA ≥0.4) after methylprednisolone treatment.

Conclusions:

  • Chinese pediatric ADS patients exhibit distinct features: earlier onset and more frequent bilateral involvement.
  • NMOSD in this population is associated with severe visual impairment and reduced RNFL thickness.
  • Methylprednisolone is effective for visual recovery in pediatric ON and NMOSD.
