Living with Aland island eye disease

An inherited eye condition present from early life with reduced vision, shaky eye movements, and trouble seeing in the dark.

Understanding Aland island eye disease

Aland island eye disease is an X-linked recessive disease of the retina that affects vision.

It involves a pale back of the eye (fundus hypopigmentation), reduced sharpness of vision, rapid involuntary eye movements (nystagmus), astigmatism, nearsightedness that slowly worsens, trouble adjusting to the dark, and a type of red-green color blindness (protanopia). It starts in newborns and infants.

Signs & symptoms

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

  • Reduced sharpness of vision
  • Nearsightedness (myopia)
  • Astigmatism
  • Trouble adjusting from light to dark
  • Color vision problems
  • Pale back of the eye (fundus hypopigmentation)

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 CACNA1F are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
