Study Summary

The purpose of this study is to determine if there are microbiologic alterations of the ocular surface after hot tub exposure. The study will evaluate the number of microbes before and after hot tub use in order to find out whether hot tub exposure has any change on the organisms present on the ocular surface. Participants will be randomized to dunk or not to dunk their head during their time in the hot tub.

Primary Outcome

Genus-species will be identified for each sample, and quantified with an ordinal scale (0-4). The total of this score will be the quantity for that person-time. The primary analyses will be a Wilcoxon Rank Sum test (Mann-Whitney) between the two arms at the follow-up time point (randomized comparison of dunk vs no-dunk), and a Wilcoxon Signed Rank test between pre-hot-tub and post-hot-tub (longitudinal comparison of all cases). We estimate that a total of 20 subjects will provide 80% power to d
