[Optic neuritis--from diagnosis to optic nerve transplantation]

Area of Science:

• Ophthalmology
• Neuroscience
• Clinical Medicine

Context:

• Optic neuritis diagnosis and treatment have evolved since its initial description in 1884.
• Visually evoked cortical potentials (VECP) and pattern VECP (PVECP) are crucial diagnostic tools, particularly for identifying subclinical optic nerve involvement in conditions like multiple sclerosis (MS).
• Ophthalmic factors significantly influence VECP results, necessitating tailored diagnostic approaches.

Purpose:

• To review diagnostic and therapeutic strategies for optic neuritis based on a 272-case cohort (1978-1999).
• To investigate racial differences in optic neuritis and its progression to MS.
• To evaluate the efficacy of steroid therapy and explore novel optic nerve regeneration techniques.

Summary:

• A review of 272 optic neuritis cases revealed no racial disparities and confirmed that sub-Tenon steroid injections are the most effective treatment.
• Experimental studies in rats and mice explored optic nerve regeneration using neurotrophic factors and artificial grafts, achieving a 15% axon regeneration rate.
• Findings suggest optic nerve transplantation holds future clinical potential, analogous to advancements in corneal and intraocular lens transplantation.

Impact:

• This research clarifies diagnostic criteria and treatment effectiveness for optic neuritis, challenging previous assumptions about racial differences.
• The study highlights the importance of ophthalmic factors in VECP interpretation for MS diagnosis.
• Pioneering optic nerve regeneration research provides a foundation for future therapeutic interventions in vision restoration.
