Pseudomonas corneal ulcer. The causative role of contaminated eye cosmetics.

The clinical significance of contaminated ocular cosmetics is illustrated by the case of a 47-year-old woman in whom a Pseudomonas corneal ulcer developed immediately after she sustained minor corneal trauma with a mascara applicator. Pseudomonas aeruginosa was cultured from the corneal ulcer and the mascara. In addition to the causative role in acute corneal ulcers, contaminated eye cosmetics contribute to chronic external eye infections. Retail eye cosmetics are typically free of contamination when purchased. The inoculation of the cosmetic occurs during normal use.
