Diagnosis and classification of optic neuritis

Area of Science:

• Ophthalmology
• Neurology
• Immunology

Background:

• Optic neuritis lacks standardized diagnostic criteria, complicating the early identification of associated neurological disorders.
• Accurate diagnosis is crucial for timely treatment of conditions such as multiple sclerosis, neuromyelitis optica spectrum disorder, and MOGAD.
• The etiology and management of optic neuritis vary globally due to geographical, ethnic, and resource-related factors.

Purpose of the Study:

• To develop and propose novel diagnostic criteria for optic neuritis.
• To establish a classification system for optic neuritis subgroups.
• To facilitate accurate and timely diagnosis, guiding treatment and research.

Main Methods:

• Clinical features were used to define criteria for possible optic neuritis.
• Paraclinical investigations including neuroimaging (brain, orbital, retinal) and biomarker analysis (antibodies, proteins) were employed for definite diagnosis.
• Retrospective analysis of stored samples and historical scans is proposed for validation.

Main Results:

• Proposed diagnostic criteria enable a diagnosis of possible optic neuritis based on clinical presentation.
• Integration of paraclinical data refines the diagnosis to definite optic neuritis.
• The criteria and classification offer potential for reduced misdiagnosis and informed treatment strategies.

Conclusions:

• The developed criteria and classification system address the current lack of consensus in optic neuritis diagnosis.
• These advancements can improve the management of patients with optic neuritis, particularly those with underlying demyelinating diseases.
• The criteria support future research by providing a standardized framework for disease course assessment and treatment trial design.
