Living with Progressive external ophthalmoplegia

A condition that slowly weakens the eye muscles and causes drooping eyelids, usually starting in adulthood.

Understanding Progressive external ophthalmoplegia

Progressive external ophthalmoplegia is a condition that causes weakness of the eye muscles and slowly worsens over time.

It typically appears in adults between ages 18 and 40. The first sign is usually drooping eyelids (ptosis), followed by weakness or paralysis of the muscles that move the eye. People may also have general muscle weakness. Some people have extra signs, and this is called progressive external ophthalmoplegia plus (PEO+).

Signs & symptoms

Symptoms vary from person to person. GARD describes these features:

  • Drooping eyelids (ptosis)
  • Weak eye muscles (ophthalmoplegia)
  • Muscle weakness in the neck, arms, or legs
  • Tiredness or weakness with exercise
  • Trouble swallowing (dysphagia)
  • Hearing loss, nerve damage, or poor coordination in PEO+

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.

  4. Connect with expert centers

    Muscular Dystrophy Association, United Mitochondrial Disease Foundation and MitoAction may keep lists of experts for this condition.
