Vision Changes
Vision changes can indicate multiple sclerosis (optic neuritis), brain tumors, stroke, or autoimmune eye disease. Optic neuritis — painful vision loss in one eye — is often the first symptom of MS.
Body System: Neurological / Ophthalmological
Related Diseases
- Multiple Sclerosis — Optic neuritis occurs in 50% of MS patients, often as the presenting symptom. Demyelination of the optic nerve causes acute painful vision loss.
- Brain Tumors — Tumors affecting visual pathways cause progressive visual field deficits or papilledema from raised intracranial pressure.

Frequently Asked Questions
Is optic neuritis always multiple sclerosis?
No — while optic neuritis is strongly associated with MS (50% of first presentations), it can also occur in neuromyelitis optica (NMO/NMOSD), MOG antibody disease, infections, and sarcoidosis. MRI brain (showing white matter lesions) and CSF analysis (oligoclonal bands) help distinguish MS from other causes.
