Optic Neuritis Diagnosis and Treatment Strategies

Optic neuritis is characterised by acute inflammation of the optic nerve, presenting with pain on eye movement, rapid visual loss and changes in colour perception. Diagnosis relies on a combination of clinical assessment, visual function testing and ancillary investigations. Magnetic resonance imaging reveals nerve enhancement and helps to identify demyelinating lesions, while visual evoked potentials quantify conduction delay. Early differentiation between isolated optic neuritis and that associated with multiple sclerosis is crucial, as it informs therapeutic choices and prognosis. High‐dose corticosteroids remain the standard of care to accelerate recovery, though they do not alter long‐term visual outcome. Disease‐modifying therapies are indicated for patients at high risk of conversion to multiple sclerosis, and investigational agents targeting neuroprotection and remyelination are under evaluation. Emerging biomarkers—genetic, immunological and imaging—are fostering a more personalised approach to risk stratification and treatment optimisation on a global scale.

Research from Nature Portfolio

Recent studies have demonstrated that integration of a genetic risk score for multiple sclerosis with demographic factors significantly enhances prediction of disease conversion in patients presenting with undifferentiated optic neuritis. By stratifying individuals into risk quartiles, researchers achieved more accurate forecasts of incident multiple sclerosis, enabling earlier consideration of disease-modifying therapy in those at highest risk. Validation across independent cohorts emphasises the potential of precision-based models to transform clinical decision-making and reduce undetected progression in diverse populations.

Technical terms

Genetic risk score: Composite index of multiple genetic variants weighted by their association with a disease, used to estimate an individual’s inherited predisposition.

Mendelian randomization: Epidemiological method that leverages genetic variants as instrumental variables to infer causal relationships between risk factors and health outcomes.

Visual evoked potential: Measurement of electrical activity in the visual cortex in response to a visual stimulus, reflecting the integrity and conduction speed of the optic nerve.
