Living with Blindness - scoliosis - arachnodactyly syndrome

A rare genetic syndrome with vision loss that gets worse, curved spine, and long thin fingers and toes.

Understanding Blindness - scoliosis - arachnodactyly syndrome

Blindness - scoliosis - arachnodactyly syndrome is a rare genetic syndrome with worsening vision loss, a curved spine, and long, slender fingers and toes.

Signs start in childhood or the teen years. Eye findings can include cloudy lens (cataract), a partly shifted lens, retinal changes, and crossed eyes.

Signs & symptoms

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

  • Vision loss that worsens over time
  • Curved spine (scoliosis)
  • Long, slender fingers and toes (arachnodactyly)
  • Cloudy lens (cataract)
  • Lens partly out of place
  • Crossed eyes (strabismus)

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 autoimmune and inflammatory disease specialists, bone and joint 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.
