Living with Oculopharyngodistal myopathy

A rare inherited adult-onset muscle disease affecting the eyelids, throat, and the muscles of the lower legs and arms.

Understanding Oculopharyngodistal myopathy

Oculopharyngodistal myopathy (OPDM) is a rare, adult-onset inherited muscle disease that affects the eyes, throat, and the muscles of the limbs far from the center of the body.

People develop eyelid drooping, trouble swallowing, a hoarse and nasal voice, and weakness and muscle wasting in the legs and arms. Many have breathing problems from weak breathing muscles. In rare cases there is hearing loss. A blood test may show raised creatine kinase and an EMG may be abnormal. GARD lists onset as from childhood to adulthood.

Signs & symptoms

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

  • Progressive drooping of the upper eyelids (ptosis)
  • Trouble swallowing (dysphagia)
  • Weakness in the lower legs and forearms
  • Weak eye muscles (progressive external ophthalmoplegia)
  • Hoarse, nasal voice
  • Breathing problems from weak muscles

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

    Muscular Dystrophy Association may keep lists of experts for this condition.
