Early treatment for isolated optic neuritis improves visual outcomes. Patients receiving treatment sooner achieved better vision compared to those treated later, highlighting the importance of timely intervention.

Area of Science:

  • Ophthalmology
  • Neuro-ophthalmology
  • Neurology

Background:

  • Optic neuritis is an inflammatory condition affecting the optic nerve.
  • Intravenous methylprednisolone is a common treatment for optic neuritis.
  • Understanding clinical characteristics and visual outcomes is crucial for patient management.

Purpose of the Study:

  • To determine clinical characteristics of patients diagnosed with optic neuritis.
  • To evaluate visual outcomes following intravenous methylprednisolone treatment.
  • To compare outcomes between isolated optic neuritis and optic neuritis with demyelinative disease.

Main Methods:

  • Retrospective review of 81 patients with optic neuritis.
  • Patients categorized into isolated optic neuritis (Group I) and optic neuritis with demyelinative disease (Group II).

  • Analysis of visual acuity before and after intravenous methylprednisolone treatment.

    • Main Results:

    • 63 patients (77.8%) had isolated optic neuritis; 18 (22.2%) had optic neuritis with demyelinative disease.
    • After treatment, 60% of isolated optic neuritis patients and 24% of those with demyelinative disease achieved visual acuity of 6/12 or better.
    • Isolated optic neuritis patients treated within 8 days showed 75% visual acuity better than 6/9.

    Conclusions:

    • Earlier treatment for isolated optic neuritis is associated with better final visual outcomes.
    • Timely intervention is critical for maximizing vision recovery in optic neuritis patients.
    • Clinical characteristics and prompt treatment influence visual prognosis in optic neuritis.
