Quick answer

Nystagmus is a condition where the eyes make repeated, uncontrolled movements, which can reduce vision. It can be present from early childhood or develop later in life. Early-onset nystagmus is usually lifelong, while new nystagmus in an adult needs assessment to find the cause.

## What it is

Nystagmus is involuntary, rhythmic movement of the eyes, usually from side to side but sometimes up and down or in circles. Because the eyes cannot hold steady, it can reduce how clearly and steadily a person sees.

## Common symptoms

Effects vary widely between people.

- Eyes that wobble or move on their own
- Reduced or blurred vision
- A head turn or tilt to find the steadiest 'null point'
- In acquired cases, a sense that the world is moving (oscillopsia)

## Causes and types

Early-onset (infantile) nystagmus appears in the first months of life and may occur on its own or with other eye conditions. Acquired nystagmus develops later and can be linked to neurological conditions, certain medicines, or inner-ear problems, so it always needs assessment.

## Management

There is no simple cure for most nystagmus, but vision can be supported with the correct glasses, low-vision aids, and good lighting. Treating any underlying cause is important, and in selected cases surgery or medication can reduce the movement or improve a head posture.

## Frequently asked questions

### Can nystagmus be cured?

Most early-onset nystagmus is lifelong and cannot be fully cured, but vision can be supported with glasses and low-vision aids. Acquired nystagmus may improve if the underlying cause is treated.

### What causes nystagmus?

Early-onset nystagmus often occurs on its own or with other eye conditions. Nystagmus that starts later in life can be linked to neurological or inner-ear problems and needs assessment.

### Does nystagmus get worse?

Early-onset nystagmus is usually stable, though it can vary with tiredness or stress. New or worsening nystagmus in an adult should always be checked by a clinician.

Write down what has changed, when it started, your current medicines and the questions you want answered. Take these to your eye-care appointment.

Sudden loss of sight, severe eye pain or a dark curtain across vision needs immediate assessment. Do not wait to complete a worksheet.
