Living with Autosomal dominant progressive external ophthalmoplegia

A genetic condition that slowly weakens the muscles that move and lift the eyes.

Understanding Autosomal dominant progressive external ophthalmoplegia

Autosomal dominant progressive external ophthalmoplegia is a rare genetic condition that slowly weakens the muscles around the eyes.

The weakness causes drooping eyelids (ptosis) and trouble moving the eyes. Other signs can include weakness in other muscles, cataracts, hearing loss, nerve problems, balance trouble, and depression. Onset is usually in the teen years or adulthood. It is usually less severe than the autosomal recessive form.

Signs & symptoms

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

  • Drooping upper eyelids (ptosis)
  • Weak eye muscles (ophthalmoplegia)
  • Weakness in the arms and legs
  • Trouble exercising for as long as usual
  • Tiredness (fatigue)
  • Slow movements and resting tremor

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 brain and nervous system specialists, 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.

  4. Connect with expert centers

    United Mitochondrial Disease Foundation and MitoAction may keep lists of experts for this condition.
