Ligneous conjunctivitis exacerbated by Pseudomonas aeruginosa - Diagnostic and therapeutic approach

Ligneous conjunctivitis is a rare disease in which pseudomembranes develop on the mucosal surfaces of the eye. Only a handful of cases have been reported in the past 100 years. Although plasminogen deficiency is largely implicated in the pathogenesis of this condition, infectious agents are also thought to play a role in worsening the disease. Treatment is usually challenging. We present a case of 3-year-old female in whom a multidrug-resistant Pseudomonas aeruginosa was isolated from the culture of the pseudomembranes. To the best of our knowledge, this is the first time P. aeruginosa has been implicated as an exacerbation factor. Furthermore, we have given merit to the triple regimen of corticosteroids, heparin, and cyclosporine as being effective. We also added antibiotics to target the infectious organism.
