Casual Wine Drinkers Less Likely to Get Cataracts

 

A glass of wine a day may keep the doctor away, according to a new study from Moorfield’s Eye Hospital NHS Foundation Trust and University College London. The study was published in Ophthalmology and showed people who drank low to moderate amounts of alcohol were less likely to need cataract surgery. Reviewing data from 490,000 volunteers, research suggested that low to moderate wine drinkers in particular were the least likely to develop cataracts compared with nondrinkers and drinkers of other types of alcohol. This study is the largest of its type to date.

What Are Cataracts?

A cataract is when your eye's natural lens becomes cloudy. Proteins in your lens break down and cause things to look blurry, hazy, or less colorful. Treatment includes surgery, where the cataract is removed and replaced with a clear artificial lens.

What Is Considered Moderate Drinking?

Moderation was a key takeaway from this research. People who drank more than the suggested amount on a daily basis had about a 6 percent higher risk of cataract surgery compared to people who drank low to moderate amounts of alcohol. Moderate drinking was defined as about 6.5 glasses of wine a week.

Is Wine Good For Eye Health?

Previous studies have also suggested that red wine and diets rich in antioxidants may prevent cataract development. Cataract development may be due to gradual damage from oxidative stress during aging. The fact that the findings were particularly evident in wine drinkers may suggest a protective role of polyphenol antioxidants, which are especially abundant in red wine. However, researchers remind the public that drinking alcohol regularly is also linked to many serious chronic conditions, including heart disease, diabetes, and cancer, and that this study does not suggest excessive drinking or drastic lifestyle changes.

Early Signs of Heart Disease Appear in the Eyes

 

Eye doctors may be able to detect signs of heart disease during a comprehensive eye exam, experts say. A new study finds that people with heart disease tend to have retinas marked by evidence of eye stroke. 

Eye strokes happen when the eye is deprived of blood flow and oxygen, causing cells to die. This creates a mark, called a retinal ischemic perivascular lesion. These marks can be spotted when ophthalmologists use an imaging tool called optical coherence tomography, or OCT, to take a close look at the retina.

OCT scans of the retina are valuable ways to detect disease and dysfunction in all parts of the body — not just the eyes, says ophthalmologist and Academy spokesperson Joseph Nezgoda, MD, a retina specialist. Eye scans can detect signs of Alzheimer’s, Parkinson’s and other underlying health conditions.

How Eye Exams Can Detect Heart Disease

The eye is the only place in the body where a doctor can see the live action of blood vessels, nerves and connecting tissue without relying on an invasive procedure. That’s why eye doctors are often the first to detect health conditions including high blood pressure, high cholesterol, stroke and more. While the marks left behind by eye strokes may be present in low numbers in healthy people, those with heart disease tend to have a far greater number. Researchers arrived at these results by reviewing the medical records of 84 people with heart disease and 76 healthy people, all of whom had received a retinal OCT scan.  

Catching Heart Disease Early Can Save Lives

The new study adds to the list of health conditions an eye exam may help detect. 

For people with heart disease-the number one cause of death worldwide-early diagnosis and treatment could help stave off a heart attack or stroke. Your eye doctor may refer you to a cardiologist if they spot eye strokes on an OCT scan, especially if you haven’t had a comprehensive health check or even a family history of heart disease.
