Cataract removal tied to lower dementia risk

An observational study published online Dec. 6, 2021, by JAMA Internal Medicine found that the risk of developing dementia was 29% lower in people who underwent cataract removal, compared with people who didn't have cataracts removed.

Could cataract surgery protect against dementia?

Having surgery to remove cataracts restores blurred or distorted vision, helping to improve quality of life for older adults. Now, a new study makes a strong case that removing cataracts may reduce a person's risk of developing dementia.

Eye diseases linked to a higher risk of dementia

People who get age-related macular degeneration, cataracts, and diabetes-related eye disease may have a higher risk for dementia. Having more than one eye condition may further increase the risk.

Watch out for these balance busters

Many factors can impair balance and lead to falls, such as vision, hearing, or joint problems; medication side effects; and environmental hazards. To improve balance and reduce the risk for falls, one can remove fall hazards from the home, treat underlying conditions that increase fall risk, consider adjusting medications that affect balance, get physical therapy, use an assistive walking device, wear supportive shoes that hold the feet in place, and frequently challenge balance with balance exercises.

Exercising safely with hearing or vision impairment

Certain adjustments can help someone with vision or hearing problems to exercise safely. For example, it may help to take a buddy on a walk, someone who can act as an extra set of eyes and ears. Stand in the front of an exercise class for a better view and a better chance to hear instructions. And it may help to get additional equipment, such as prescription sports glasses or a remote microphone for a hearing aid.

In your eyes: Clues to heart disease risk?

The eyes may provide clues to the presence of cardiovascular disease. Ocular (eye) strokes can foreshadow a more serious stroke, and early damage to tiny eye blood vessels can be a harbinger of heart problems. Diabetes and high blood pressure (both common risk factors for heart disease) can damage vessels that supply the retina. Some middle-aged and older adults develop soft, yellowish, cholesterol-filled bumps on or around their eyelids. Called xanthelasmas, they can be a sign of high levels of cholesterol, triglycerides, or other fats in the blood, which also raises heart disease risk.

Back to the doctor

People who’ve skipped medical check-ups for a while should visit their primary care doctor, dental hygienist, and eye doctor. A primary care doctor will consider a person’s blood pressure, medications, weight, alcohol intake, gait, balance, memory, hearing, mood, and levels of physical activity and socialization. To prepare for the visit, one should write down questions for the doctor and bring a list of all medications. At the appointment, one should take notes and ask any questions needed to understand the doctor’s instructions.

Can wearing contacts harm your vision?

Millions of people wear contact lenses, and with proper use and care they are very safe. However, sleeping with lenses in that are not specifically intended for extended wear can increase the risk of infection in the eye's cornea.

You don't say? Under eye bags and dark circles

Bags and dark circles under the eyes are caused not by lack of sleep, but by a variety of factors. Treatment options are limited, but some home remedies might help.

What are eye floaters?

Eye floaters occur when the thick, jelly-like substance that fills the center of the eye form blobs that block incoming light. They might resemble spots, cobwebs, or strings. The sudden appearance of new floaters should prompt a call to your doctor, but most often they become less bothersome over time.
