Klebsiella and acute anterior uveitis.

Samples of the faeces of 153 consecutive patients presenting with acute anterior uveitis (AAU), and of 47 controls were examined for the presence of Klebsiella pneumoniae. No increase in the carriage rate of klebsiella was found in the AAU patients as compared with the controls. Furthermore no increase was found in any group of patients whether subdivided by HLA-B27 status, sex, or presence of ankylosing spondylitis (AS). No difference was found between patients having their first attack of AAU and those with recurrences.
