Living with Iridocorneal endothelial syndrome

A group of eye conditions, usually in one eye, with changes to the iris, a swollen cornea, and glaucoma.

Understanding Iridocorneal endothelial syndrome

Iridocorneal endothelial (ICE) syndrome is a group of eye diseases with changes in the iris, swelling of the cornea, and glaucoma.

ICE syndrome is more common in women than men and usually affects only one eye. It includes three closely linked conditions: Cogan-Reese syndrome, Chandler's syndrome, and essential (progressive) iris atrophy. It is usually seen in adults. Glaucoma is a disease that can cause serious vision loss when fluid cannot drain properly from the eye.

Signs & symptoms

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

  • Glaucoma
  • Swelling of the cornea
  • Less clear vision
  • Slow loss of vision over time
  • Wearing away of the iris (iris atrophy)
  • Pupil pulled out of place

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.
