Ligneous conjunctivitis exacerbated by Pseudomonas aeruginosa - Diagnostic and therapeutic approach

Area of Science:

• Ophthalmology
• Infectious Diseases
• Genetics

Background:

• Ligneous conjunctivitis is a rare, chronic inflammatory condition characterized by pseudomembrane formation on ocular mucosal surfaces.
• Plasminogen deficiency is the primary suspected cause, but infectious agents may exacerbate the disease.
• Treatment for ligneous conjunctivitis is often challenging and requires a multifaceted approach.

Observation:

• A 3-year-old female presented with ligneous conjunctivitis.
• Cultures from the pseudomembranes isolated a multidrug-resistant strain of Pseudomonas aeruginosa.
• This marks the first reported instance of P. aeruginosa involvement in exacerbating ligneous conjunctivitis.

Findings:

• A multidrug-resistant Pseudomonas aeruginosa strain was identified as a potential exacerbating factor in a pediatric case of ligneous conjunctivitis.
• A treatment regimen combining corticosteroids, heparin, and cyclosporine, supplemented with targeted antibiotics, demonstrated efficacy.
• This case highlights the potential role of bacterial infections in the pathogenesis and exacerbation of ligneous conjunctivitis.

Implications:

• The findings suggest that infectious agents, specifically multidrug-resistant Pseudomonas aeruginosa, can play a significant role in the exacerbation of ligneous conjunctivitis.
• The successful use of a triple therapy regimen (corticosteroids, heparin, cyclosporine) plus antibiotics offers a promising therapeutic strategy for complex cases.
• This case underscores the importance of identifying and treating infectious agents in ligneous conjunctivitis for improved patient outcomes.
