Summary
Herpes zoster ophthalmicus (HZO) optic neuritis is rare but diagnosable with MRI. Prompt treatment with acyclovir and steroids effectively restores vision in HZO optic neuritis patients.
Area of Science:
- Ophthalmology
- Neurology
- Infectious Diseases
Background:
- Optic neuritis is an uncommon complication of herpes zoster ophthalmicus (HZO).
- This study details two rare cases of HZO-associated optic neuritis.
Observation:
- One patient presented with anterior optic nerve involvement, the other with retrobulbar optic neuritis.
- Magnetic resonance imaging (MRI) revealed peripheral enhancement of the optic nerve sheath complex on contrast-enhanced T1-weighted scans.
Findings:
- MRI is a valuable tool for diagnosing HZO optic neuritis.
- Both patients experienced complete vision recovery within three months of treatment initiation.
Implications:
- Early diagnosis and treatment are crucial for favorable outcomes in HZO optic neuritis.
- Combined therapy with systemic acyclovir and corticosteroids demonstrates efficacy in managing HZO optic neuritis.
