An unusual presentation of diabetes mellitus

Three middle-aged and elderly patients presenting with their first attack of acute anterior uveitis (AAU) were found to have previously undiagnosed diabetes mellitus. A first attack of AAU is unusual in this age group and may indicate underlying systemic disease. Diabetes is an infrequent cause of uveitis but should be considered in the differential diagnosis. It is important to be aware of this uncommon presentation of the disease, thereby stating the value of performing routine urinalysis in AAU.
