Living with Muscle eye brain disease

A rare inherited muscle condition that also affects the eyes and brain, starting before or soon after birth.

Understanding Muscle eye brain disease

Muscle eye brain disease (MEB) is a rare inherited condition that affects the muscles, eyes, and brain.

MEB is one of the congenital muscular dystrophies (inherited muscle conditions present from early life). People have low muscle tone, severe nearsightedness, glaucoma, and brain differences. Developmental delay, intellectual disability, extra fluid in the brain (hydrocephalus), and distinct facial features can also occur.

Signs & symptoms

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

  • Low muscle tone (hypotonia)
  • Severe nearsightedness (myopia)
  • Glaucoma
  • Extra fluid in the brain (hydrocephalus)
  • Seizures
  • Delayed development and learning problems

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, genetic specialists and seizure and epilepsy 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 and Epilepsy Foundation may keep lists of experts for this condition.
