Living with Early-onset non-syndromic cataract

An inherited eye condition with cloudy lenses (cataracts) in both eyes, present at birth or early childhood, without other body systems affected.

Understanding Early-onset non-syndromic cataract

Early-onset non-syndromic cataract is a rare inherited eye condition in which the lenses become cloudy at birth or in early childhood.

The cataracts are usually in both eyes, look the same in each eye, and do not get worse over time. Some people also have other eye differences, such as small corneas or eyes, gaps in the eye structure (colobomas), shaking eyes (nystagmus), or nearsightedness. Other organs and body systems are usually not affected.

Signs & symptoms

GARD doesn't list specific symptoms for this condition separately, but the summary describes these features:

  • Cloudy lenses (cataracts) in both eyes
  • Cataracts present at birth or early childhood
  • Eye shaking (nystagmus) in some people
  • Small cornea or small eye size in some people
  • Nearsightedness in some people

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

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include eye disease specialists and genetic specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
