Cho CH, et al. - Researchers compared the clinical characteristics and antibiotic susceptibilities in patients with Pseudomonas aeruginosa (PA) and P. putida (PP) keratitis at a tertiary referral center in South Korea. Findings suggested a close association of the PA group with younger age, wearing contact lenses, shorter symptom duration, and hypopyon, whereas a more close association of the PP group with the elderly age, corneal trauma, and decreased the efficacy of the beta-lactams was seen. Between the two groups, no significant difference was seen in clinical outcomes. For poor clinical outcome, the risk factors were previous ocular surface disease and hypopyon.
