Drinking may worsen the vision of diabetics

Moderate alcohol consumption among individuals with type 2 diabetes may increase the risk of poor visual acuity, according to a new study from UK researchers.

Diabetics are often warned against drinking. It has been linked to an increased risk of a range of health disorders, including loss of vision. While some experts have connected drinking to diabetic retinopathy, the new study found alcohol's effects on vision may not go that far.

Instead, they found that moderate alcohol consumption (one to 14 drinks per week) decreases visual acuity among diabetics. While this may not be as severe as diabetic retinopathy, the researchers warned that it may severely impact an individual's quality of life.



For the study, which was published in the journal Diabetic Medicine, researchers from the Institute of Metabolic Sciences in Cambridge, UK followed a group of 1,239 adults with type 2 diabetes for over five years. They found that participants who drank regularly were almost twice as likely to suffer impairment of visual acuity.



"Alcohol consumption is associated with increased risk of deterioration of visual acuity, but not with retinopathy in individuals with Type 2 diabetes," the researchers wrote in their report.
