Living with Leber optic atrophy

An inherited condition that causes vision loss, mostly in central vision, usually beginning in the teens or twenties.

Understanding Leber optic atrophy

Leber optic atrophy, also called Leber hereditary optic neuropathy (LHON), is an inherited form of vision loss.

It usually begins in the teens or twenties, with blurry or cloudy vision in one or both eyes. It mainly affects central vision, which is needed for reading, driving, and recognizing faces. Males are affected much more often than females, for unknown reasons.

Signs & symptoms

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

  • Blurred vision
  • Central blind spot (central scotoma)
  • Damage to the optic nerve (optic atrophy)
  • Progressive loss of vision
  • Slow decrease in sharpness of vision
  • Twisting of small blood vessels in the retina

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

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

InheritanceMitochondrial

It is caused by changes in mitochondrial genes, which are passed down in a mitochondrial pattern of inheritance. Vision loss comes from damage to cells in the optic nerve.
