I. The Disease of Diabetic Retinopathy

Diabetic retinopathy is a disease that causes impaired vision or even total blindness. It does so by damaging blood vessels in the retina. The retina is needed for vision. This disease usually affects both eyes. And it can affect anyone with diabetes. That is, either type 1 or type 2.

In early stages of the disease, there may be no symptoms. However, as it progresses, symptoms may include these.

    • Blurred vision.
    • Dark or empty areas in vision.
    • Floaters (That is, spots or strings that float in vision).
    • Fluctuating vision.
    • Impaired color vision. 

II. The Study

alcohol and diabetic retinopathyResearchers studied alcohol and diabetic retinopathy over time among 656 people with diabetes. All had retinal photos taken at the beginning of the study and six years later at follow-up. The researchers also had data on drinking quantity and frequency and other relevant data.

The researchers found that diabetics who drank alcohol had nearly two-thirds lower risk of developing the disease. That was in comparison with non-drinkers. However, their was no association between drinking and progression of the disease once it began.

The study was published in the journal Ophthamology.

So the bottom line is simple. Drinking alcohol greatly reduces the chance of getting this serious eye disease.

avoid frailty in ageingAnd moderately drinking any form of alcohol generally has equal health benefits. That is, wine, beer, and spirits are all helpfu. (Spirits are whiskey, gin, tequila, rum, vodka, etc.)

III. Risk Factors for Diabetic Retinopathy

Anyone who has diabetes can develop diabetic retinopathy. Risk of developing it can increase as a result of these.

    • alcohol and diabetic retinopathyAbstinence from alcohol.
    • Being African American, Hispanic or Native American.
    • Duration of diabetes (As duration increases, so does risk).
    • High blood pressure.
    • High cholesterol.
    • Poor control of blood sugar.
    • Pregnancy.
    • Tobacco use.
