People with Type 2 Diabetes who Consume Alcohol at Increased Risk for Blurry Vision
A new study published in the journal Diabetic Medicine reveals that among patients with type 2 diabetes, alcohol consumption was associated with an increased risk of deterioration of visual acuity.
Patients with type 2 diabetes are at increased risk to develop complications like cardiovascular disease, renal disease, and retinopathy. Previous studies have suggested that moderate alcohol consumption could reduce the risk of cardiovascular disease and other complications among type 2 diabetes patients.
Researchers led by Joline WJ Beulens, PhD, of the University Medical Center Utrecht, studied over 1,200 type 2 diabetes patients over five and half years and reviewed current and past consumption of wine, spirits, and beer. Moderate alcohol consumption was defined as one to 14 drinks a week and heavy alcohol consumption was defined as more than 14 drinks a week.
Findings reveal that alcohol consumption was associated with a more than 50% increased risk of deterioration of visual acuity over that time but was not related to typical diabetes related eye disease. Deterioration was defined by a decrease of two lines in best vision in either eye.
“Our study is the first to show this association,” said Dr. Beulens. “Lifestyle factors, including alcohol consumption, may alter the risk of visual loss in individuals with diabetes. This is a first observational study and our findings should be replicated.”
