[Diabetes mellitus--not an aetiological factor of uveitis? (author's transl)].

Out of 103 patients with uveitis, 14.5% of the cases showed pre-clinical diabetes mellitus. This number exceeds by far the average frequency of approx. 6% of pre-clinical diabetes. On account of these findings, the diabetes mellitus is assumed to be a co-factor of the development of uveitis. In order to clarify the cause of uveitis, the glucose tolerancetest should be given preference in the diagnosis.
