# What is congenital cataract?

Congenital cataract is a lens opacity present at birth or developing in early infancy. It can affect one or both eyes and may interfere with normal visual development.

## Causes

Some congenital cataracts are hereditary, while others result from metabolic disorders, intrauterine infections, or structural eye anomalies. In many cases, no clear cause is identified despite investigation.

- Can occur in isolation or as part of a wider syndrome
- Severity ranges from small, non-significant opacities to dense cataracts
- Early detection through newborn and childhood screening is vital

## Impact on Vision

Dense cataracts in early life can prevent the visual system from developing properly, leading to amblyopia. Prompt assessment by paediatric eye specialists is therefore crucial.

## Treatment

Significant congenital cataracts are usually managed surgically, with visual rehabilitation using glasses or contact lenses.
