Age-related macular degeneration (ARMD) is one of the leading causes of vision impairment in the elderly and its frequency in general population increases with aging. The ethiology of this disease has remained so far unknown. The rela tionship between ARMD and diabetes mellitus was studied in the present work. Fundus oculi was investigated in 292 diabetic patients older than 50 years and with more than 14 years of duration of diabetes (time since diagnosis). A group of 375 non diabetic, non hypertensive subjects matched for age was studied as control. ARMD frequency was significantly higher in diabetics compared to controls (p <0.005); and also in type II diabetics (non-insulin dependent diabetes mellitus = NIDDM) compared to type I (insulin dependent diabetes mellitus = IDDM) (p <0.001). Older diabetic patients showed an increased frequency of ARMD while no correlation with the duration of the disease emerged. Macular damage was not linked to microangiopathy (retinopathy), hypertension or gender; on the contrary, it appeared to be associated with dyslipidemia. On the basis of these data one can conclude that diabetes mellitus can exert an unfavorable effect on macular age-related phenomena even if the pathogenetic mechanism is at present obscure.
