H10.513
Ligneous conjunctivitis, bilateral
Clinical Classification Guidelines
Medical Intelligence & Overview
Bilateral ligneous conjunctivitis is a rare inflammatory eye disorder characterized by the development of thick, woody, fibrin-rich plaques on the conjunctiva—the clear tissue covering the white part of the eye and inside of the eyelids. It predominantly affects both eyes and can lead to discomfort, vision problems, and potential scarring if left untreated. Recognizing this condition early is crucial for appropriate management and to prevent long-term damage.
Causes & Symptoms
Clinical Causes: Genetic mutations affecting fibrinolytic activity, leading to abnormal fibrin deposition Deficiency of plasminogen, a protein essential for dissolving fibrin clots, which results in persistent fibrin deposition on the conjunctiva Hereditary factors, often inherited in an autosomal recessive pattern No clear association with environmental or infectious causes in most cases
Key Symptoms: Thick, woody, fibrinous plaques on the conjunctiva, which may appear as yellowish or brownish deposits Persistent conjunctivitis with redness and irritation Eye discomfort, including burning or gritty sensation Decreased visual acuity due to plaque formation or scarring In some cases, eyelid swelling and conjunctival fibrosis
Diagnostic & Treatment
Diagnosis Path: Slit-lamp examination revealing characteristic fibrin-rich plaques Histopathological analysis of conjunctival tissue showing extensive fibrin deposits Laboratory tests to measure plasma plasminogen levels, which are often low Genetic testing may be employed to identify mutations associated with plasminogen deficiency
Treatment Protocols: Topical corticosteroids to reduce inflammation Use of topical antifibrinolytic agents like plasminogen or cyclosporine Surgical removal of persistent plaques, often combined with medical therapy to prevent recurrence Systemic plasminogen replacement therapy in cases with significant plasminogen deficiency Regular monitoring to detect recurrence or complications such as scarring or vision loss
