Vision problems

Your eyes play an important role in helping you understand the world around you. The optic nerve (eyes) sends visual information to the brain, which the brain processes into what you see.

MS can damage the nerve pathways in the brain and the optic nerve, which can cause temporary or ongoing visual problems. It rarely results in total blindness.

With support and advice from your healthcare team, you can manage this symptom and live better with MS.

MS vision impairment

What to do if you experience vision issues

If you notice eye pain, faded colours, double or blurred vision, blind spots or other MS eye symptoms – talk to your GP or MS nurse as soon as possible. They may arrange an eye assessment with a specialist to determine if there’s any inflammation and the best course of treatment to assist with vision issues.

How to treat vision impairment symptoms

Treatments depends on the type of eye symptom you're experiencing.

Optic neuritis

Optic neuritis may improve on its own within four to six weeks. The most common treatment is steroids (through infusion or tablets) to reduce inflammation and speed recovery.

Double vision

Temporary measures such as an eye patch or a stick-on Fresnel prism lens can help realign images. If double vision occurs during a relapse, it often improves naturally, though steroids may assist recovery. Persistent double vision may be managed with treatments like botulinum toxin or, in some cases, surgery.

Nystagmus

Nystagmus can be challenging to treat. Glasses or contact lenses may help stabilise vision. An eye care professional can teach null-point strategies and suggest tools like magnifiers or improved lighting. Some medications, such as gabapentin or memantine, may reduce involuntary eye movement. If nystagmus leads to strained posture, a physiotherapist can help manage neck or shoulder discomfort.
