Ligneous conjunctivitis is a rare bilateral chronic disorder characterized by firm (“woody”), yellowish, fibrinous pseudomembranes on the palpebral conjunctiva. It is thought to be secondary to severe deficiency in type I plasminogen and can affect persons of all ages. No single treatment is consistently effective. Surgical removal, amniotic membrane transplantation, fresh frozen plasma, and heparin have been used.
