Living with Congenital Horner syndrome
A rare condition from birth with a small pupil, a drooping upper eyelid and less sweating on one side of the face.
Understanding Congenital Horner syndrome
It is caused by damage to the sympathetic nerves of the face. In rare cases the colored part of the eye (the iris) lacks pigment.
Signs & symptoms
Symptoms vary from person to person. GARD's summary lists these:
- Small pupil (miosis)
- Drooping upper eyelid (ptosis)

- Lighter iris color, in rare cases
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
