A case control study was carried out to detect the relation between magnesium deficiency and diabetic retinopathy and to study other risk factors for diabetic retinopathy. The study involved 30 cases with diabetic retinopathy, 30 diabetics and 30 non-diabetics with normal retina as controls. Serum magnesium was significantly lower in the diabetic control group than both other groups. Significant association between diabetic retinopathy and hypertension, poor control of blood sugar, irregularity in drug treatment, lack of routine fundus examination, high gravidity and low socioeconomic status were found. Multiple regression analysis was used to adjust for all variables mentioned. Magnesium deficiency was found to be statistically significantly associated with diabetic retinopathy after considering the effects of other variables.
