An expandable plastic sponge is used to collect a uniform sample of fluid from the conjunctival sac. The uptake of fluid by the sponge and recovery of particles from the sponge is highly reproducible. The kinds of bacteria collected by the sponge were the same as those collected by a moistened swab. Collection with the sponge provides a rapid, precise, and highly reproducible method of sampling conjunctival bacteria in normal and inflamed eyes. This technique will be used in the study of the stages of disease severity and evaluation of the role of therapy in reducing bacterial counts.
