Abstract
Objectives: The aim of our study is to evaluate the possible association of
serum magnesium in diabetic patients with and without retinopathy. Study Design: Crosssectional observational. Setting: Bahawal Victoria Hospital, Bahawalpur. Period: September,
2018 to May, 2019. Material & Methods: A total of 258 subjects were enrolled in the study.
They were divided in 3 groups, which comprised of 208 diabetic patients; 92 with retinopathy,
116 without retinopathy and the control group comprised of 50 healthy individuals. Both cases
and controls were subjected to blood tests for the estimation of biochemical parameters.
Results: A considerable decrease was observed in the serum magnesium level of diabetics
in comparison with the healthy participants. The mean serum magnesium levels amongst the
groups were 1.5 ± 0.2 mg/dl and 2.4 ± 0.3 mg/dl respectively (p<0.001). There was also
a marked variation in serum levels of magnesium among diabetic retinopathy patients and
diabetics without complications i.e.1.3±0.1 mg/dl and 1.69±0.1 mg/dl respectively (p<0.001).
Conclusion: Patients suffering from diabetic retinopathy displayed significantly lower serum
magnesium levels in contrast to the control group and diabetics without retinopathy.
