Living with Wagner disease

An inherited eye condition that causes vision loss that worsens over time, starting in childhood.

Understanding Wagner disease

Wagner disease is a hereditary eye disorder that causes vision loss that worsens over time.

Eye problems typically begin in childhood, though vision loss may not be obvious at first. The retina becomes thin and may detach. The eye's gel becomes watery, and cataracts develop. Some people have nearsightedness, night blindness, or a narrowed field of vision. GARD says vision can range from near normal to complete loss in both eyes.

Signs & symptoms

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

  • Reduced clarity of vision
  • Nearsightedness (myopia)
  • Night blindness
  • Cataracts
  • Retinal detachment
  • Breakdown of the retina and choroid

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. Consider genetic testing

    Changes in VCAN are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

Wagner disease is caused by changes in the VCAN gene. A child can get it from one parent with the changed gene (autosomal dominant).
