Living with Facial dysmorphism-lens dislocation-anterior segment abnormalities-spontaneous filtering blebs syndrome

A rare inherited condition with lens of the eye out of place, other eye differences, and distinct facial features.

Understanding Facial dysmorphism-lens dislocation-anterior segment abnormalities-spontaneous filtering blebs syndrome

This rare genetic condition affects the eyes, with dislocated lenses and front-of-eye differences, along with distinct facial features.

People can develop painless clear cysts on the eye surface called filtering blebs. Facial features include flat cheeks and a prominent, beaked nose. It usually shows up in childhood or the teen years.

Signs & symptoms

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

  • Lens out of place (ectopia lentis)
  • Cataract (clouding of the lens)
  • Nearsightedness (myopia)
  • High eye pressure
  • Loose, flexible joints
  • Long, slender fingers

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. Consider genetic testing

    Changes in ASPH are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
