Living with Ankyloblepharon filiforme-imperforate anus syndrome

A rare syndrome present at birth with bands of tissue joining the eyelids and a closed anal opening.

Understanding Ankyloblepharon filiforme-imperforate anus syndrome

Ankyloblepharon filiforme-imperforate anus syndrome is a rare malformation syndrome with bands of tissue between the eyelids and anal atresia.

Stretchy bands of tissue connect the upper and lower eyelid edges, along with anal atresia (the anal opening doesn't form). Some people also have cleft palate, hydrocephalus (extra fluid in the brain), and meningomyelocele (a spinal defect). GARD says there have been no further descriptions in the literature since 1993.

Signs & symptoms

Symptoms vary. GARD lists these among the most common:

  • Bands of tissue joining the eyelids (ankyloblepharon)
  • Closed anal opening (anal atresia)
  • Missing teeth
  • Undescended testes

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 bone and joint specialists, ear, nose, and throat 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

    World Craniofacial Foundation and National Foundation for Ectodermal Dysplasias may keep lists of experts for this condition.
