An eye examination may be able to detect Alzheimer’s disease (AD) years or even decades before any clinical symptoms appear, suggests a small study published in JAMA Ophthalmology. Ophthalmologists from the Washington University School of Medicine in St. Louis discovered that people in the preclinical stage of AD had significant

There’s a good reason why high blood pressure is called the “silent killer.” While hypertension remains insidious, it is stealthily damaging not only your arteries, but every organ, tissue, and system in the body. Since all your body’s organs and tissues require the vital oxygen and nutrients from the blood
If you’re blessed with the gift of perfect or near-perfect eyesight, it can be quite jarring when you first experience a significant period of blurred vision. You’re not sure whether it’s a temporary occurrence or a sign that you might be losing your eyesight.

Graves’ disease is an autoimmune disorder characterized by hyperthyroidism (overactive thyroid). And it’s not particularly rare: It affects 1 in 200 Americans. If untreated, Graves’ disease can cause serious health issues within many of the body’s systems—and it even can prove fatal.

Chronic diseases such as heart disease, high blood pressure, stroke, and diabetes represent a major health problem in the United States.

If you’ve tried store magnifiers, reading glasses, and perhaps have had eye surgery, yet you still struggle with seeing well, you might be among the millions of American who have what’s called “low vision.”
Low vision is permanent vision loss. Problems can include trouble with contrast sensitivity, which is the ability
Normal eye pressure varies throughout the day, just like blood pressure. It’s internal eye pressure, medically called intraocular pressure, or IOP. And again, like blood pressure, normal eye pressure is defined by a range of numbers. In this case, 12 to 22 millimeters of mercury (mm Hg), the scientific scale
More than 3 million Americans have glaucoma, and just as many likely have it but aren’t aware. There are no early symptoms, and by the time there are, the disease may have advanced to the point of irreversible vision loss. Peripheral vision is the first to go, making the field
Glaucoma is an eye disease where excess pressure irreparably damages the eye, causing blindness. Because glaucoma symptoms don’t manifest until the disease is very advanced, the disease is a sneaky vision thief. Yet fewer than 10 percent of Americans surveyed know that glaucoma has no warning signs, according to the
There’s a good reason why high blood pressure is called the “silent killer.” Yet, while hypertension remains insidious, it is stealthily damaging your arteries, and also the organs and other tissues that rely on the blood that these vessels deliver to them.

Hypertension contributes to atherosclerosis, or “hardening”
