# What causes eye turning inward (esotropia)?

Esotropia is an inward turning of one or both eyes. It can appear in childhood or later life.

## Childhood causes

In children, esotropia often relates to focusing effort or muscle imbalance. Early treatment helps prevent amblyopia lazy eye.

- Accommodative esotropia linked with long-sightedness
- Congenital esotropia appearing in the first months of life
- Developmental imbalance between eye muscles
- Family history increases risk in some cases

## Adult-onset causes

In adults, new esotropia may produce double vision and often has an underlying neurological or mechanical cause.

- Decompensated childhood squint becoming symptomatic
- Cranial nerve palsies affecting eye muscles
- Thyroid eye disease or orbital trauma
- Any recent-onset eye turn with double vision needs urgent review
