We examined 202 Iranian patients with DM aged 10-86 years and 261 healthy subjects aged 10-28 years and the diagnosis of MRG was made based on clinical features. The examination indicated that 13 [6.43%] diabetic patients and 4 [1.53%] of control group had MRG. There was a significant difference in the prevalence of MRG, between patients and control group. MRG showed no association with other variables [age, sex, duration of DM, drugs, FBS, A[1C]]. In the present study the prevalence of MRG in diabetics was much higher than that of controls
