Contact Lens Related Elizabethkingia meningoseptica Keratitis- A First Southeast Asean Case Report & Literature Review.

We describe the first clinical case of contact lens related corneal ulcer caused by Elizabethkingia meningoseptica registered in Southeast Asia. A 20-year-old female student who was a regular soft contact lens wearer, presented with pain, photophobia and blurring of vision of the right eye for 3 days. On slit lamp examination, there was a small paracentral anterior stromal infiltrate with an overlying epithelial defect. Microbiological cultures from corneal scrapings, contact lens and its casing were positive for E. meningoseptica. Due to high likelihood of contact lens contamination causing keratitis, topical fortified gentamicin 0.9% and ceftazidime 5% were administered empirically. Topical vancomycin 5% was later added tailoring to the culture and sensitivity of the organism. After 8 weeks of treatment, the keratitis subsided and corneal epithelial defect completely healed with residual corneal opacity. Even though uncommon, contact lens related E. meningoseptica keratitis can occur in healthy immunocompetent individuals with no ocular comorbidities.
