Living with Congenital total cataract

A rare eye condition in which the lens is cloudy throughout in both eyes from birth or early childhood.

Understanding Congenital total cataract

Congenital total cataract is a rare eye condition that causes cloudy areas across the whole lens in both eyes.

It is present at birth or early childhood and usually does not change over time. Some people also have changes in the front of the eye, gaps in eye structures (colobomas), eye shaking (nystagmus), a small cornea or small eyes, or nearsightedness. It doesn't usually affect other parts of the body.

Signs & symptoms

GARD doesn't list specific symptoms for this condition yet. Its summary mentions these:

  • Cloudy lens in both eyes
  • Eye shaking (nystagmus)
  • Gaps in eye structures (colobomas)
  • Small cornea or small eyes

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
