Living with Cataract 8 multiple types

A rare eye disease with cloudy areas in both lenses from birth or early childhood that usually does not affect other parts of the body.

Understanding Cataract 8 multiple types

Cataract 8 is a rare eye disease that causes cloudy areas in the clear lens of both eyes.

The cloudiness is present at birth or in early childhood and usually does not change much over time. People may also have eye shaking (nystagmus), small corneas, small eyes, or gaps in parts of the eye (colobomas). Nearsightedness can occur. It does not usually affect other parts of the body.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Cloudy center of the lens (nuclear cataract)
  • Cloudy lens present at birth
  • Slowly worsening vision

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

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

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