Abstract

PURPOSE
To report a case of Acinetobacter baumannii keratitis in a soft contact lens wearer. To our knowledge, such a case has not been previously reported in South Korea.
CASE SUMMARY
A 17-year-old boy who had worn soft contact lens for 4 months came to our hospital complaining of severe ocular pain, glare, and visual disturbance in his left eye for 2 days prior to admission. On slit-lamp examination, a round 2.5x4.5 mm lesion with epithelial defects and diffuse edema was noted. Numerous keratic precipitates and hypopyon on the dependent position were also noted. Specimens from corneal scraping, the contact lens itself, and the storage case with lens cleanser solution were evaluated by bacteriology examination. The patient was treated with topical 0.5% Moxifloxacin. A few days later, Acinetobacter baumannii was isolated in a bacterial culture from a corneal specimen. The patient's clinical features improved steadily with topical 0.5% Moxifloxacin therapy. Complete epithelialization with resolution of the corneal edema and inflammatory infiltrations of the left eye was achieved after 5 days of topical Moxifloxacin therapy.
CONCLUSIONS
Along with a literature review, we report a case of successfully treated Acinetobacter baumannii keratitis in a soft contact lens wearer.

  Figure 1. (A) Slit-lamp photography at the first examination showed 2.5×4.5-mm-sized, round corneal epithelial defect with surrounding stromal edema and numerous inflammatory debris on the corneal endothelium. (B) Five days after treatment, corneal lesion showed complete epithelialization with resolution of corneal edema and inflammatory infiltrations.

  Figure 2. (A) Multiple colonies were forming on MacConkey agar, each colony showed 1.5-mm-sized, non-pigmented, dome-shaped cluster, (B) Gram stain showed various size gram-negative bacilli (Gram stain, ×1,000).
