Living with Spastic ataxia-corneal dystrophy syndrome

A rare inherited condition with unsteady, stiff movement and eye problems, with normal intelligence.

Understanding Spastic ataxia-corneal dystrophy syndrome

Spastic ataxia-corneal dystrophy syndrome is a rare hereditary ataxia that also affects the eyes.

People have a stiff, unsteady walk (spastic ataxia), cataracts in both eyes from birth, clouding of the cornea and nearsightedness. Intelligence is normal. GARD notes there have been no further descriptions in the medical literature since 1986. It starts in childhood.

Signs & symptoms

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

  • Stiff, unsteady walk
  • Cataracts present from birth
  • Corneal dystrophy (clouded cornea)
  • Nearsightedness (myopia)
  • Optic nerve damage
  • Small cerebellum

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

    National Ataxia Foundation may keep lists of experts for this condition.
