Living with Isolated cryptophthalmia

A rare condition present from birth in which the eyelids are missing and skin covers the eye, which is often smaller than usual.

Understanding Isolated cryptophthalmia

Isolated cryptophthalmia is a rare condition present from birth in which the eyelids are absent and skin covers the eye.

The eye underneath is often smaller than usual (microphthalmic). GARD notes six cases of complete cryptophthalmia in both eyes have been described. It starts during pregnancy and is seen in newborns.

Signs & symptoms

GARD doesn't list specific symptoms for this condition yet. Its summary describes these features:

  • Eyelids missing
  • Skin covering the eye
  • Smaller than usual eye (microphthalmia)

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 FREM2 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
