Living with Ligneous conjunctivitis

A rare condition that causes thick, woody growths on the lining of the eyelids and sometimes other tissues.

Understanding Ligneous conjunctivitis

Ligneous conjunctivitis is a rare condition in which a protein called fibrin builds up and causes thick, woody growths in the conjunctiva, the lining of the eye.

The growths are yellow, white, or red and most often form inside the eyelids. They may also affect the cornea and pupil and can lead to vision loss. A systemic form can affect the mucous membranes of the voice box, nose, airways, vagina, cervix, and gums.

Signs & symptoms

GARD doesn't list a symptom list for this condition. Its summary describes these features:

  • Inflamed eyes (conjunctivitis)
  • Thick, woody growths inside the eyelids
  • Vision loss if the cornea is involved
  • Growths in the nose, throat, or gums (systemic form)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.
