Ligneous conjunctivitis is a chronic disorder characterized by the growth of thick, wood-like lesions on mucous membranes. Lesions often begin in the eyes and later develop in other areas such as the nose, vocal cords, larynx, trachea, sinuses, and female genital tract. The etiology of this disease is unknown, but there is some evidence of an autosomal recessive inheritance (Ligneous conjunctivitis, 1990; National Organization for Rare Disorders [NORD], 1999).
A rare eye disease in which fibrin deposits create woody plaques on the conjunctiva. Similar plaques may develop in the airways and genitalia. The disease often is found in patients with a deficiency in plasminogen levels.
