Lifestyle choices may help glaucoma patients preserve eye sight

Northern Minnesota Eye Care offers advice on how people can take control of their health beyond medications and surgery

 

January 23, 2020



Glaucoma is one of the leading causes of vision loss, affecting about 3 million people in the United States. Because there are no symptoms early on, about half of people with the disease don’t know they have it. Once vision is lost to glaucoma, it can’t be regained. During Glaucoma Awareness Month in January, Northern Minnesota Eye Care would like to remind the public that early detection and treatment, and some lifestyle choices can help protect your sight.

Glaucoma damages the optic nerve, which transmits visual information from the retina to the brain. Typically, the disease progresses slowly, gradually destroying peripheral vision. Because people are unaware of early peripheral vision loss, a patient can lose most of it before they even know they have glaucoma. 

That’s why the Academy recommends that everyone have a comprehensive eye exam at age 40. This exam provides optometrists – physicians who specialize in eye care – an opportunity to carefully examine the eye including the optic nerve for signs of damage and other possible problems that may affect vision. Individuals at greater risk for developing glaucoma include people:

• over age 40;

• of African, Asian or Hispanic heritage;

• who have high eye pressure detected during an eye exam;

• who have experienced eye trauma or eye injury;

• whose corneas are thin in the center;

• or who have health problems such as diabetes, migraines, high blood pressure or poor blood circulation.

Appropriate treatment for glaucoma depends on the specific type and severity of the disease. Medicated eye drops or laser treatments are the most common initial approach. These techniques work by lowering eye pressure to reduce the amount of fluid in the eye, and by increasing fluid outflow from the eye.

Beyond drugs and surgery, several recent studies suggest that lifestyle choices may also help minimize the risk of losing vision to glaucoma.

Exercise regularly. A study just published in the journal, Ophthalmology, showed that people who engaged in physical activity can slow vision loss from glaucoma.

Meditate. A new study published last month in the journal, Glaucoma, showed that a relaxation program with meditation can lower eye pressure in glaucoma patients and improve their quality of life by lowering stress hormones like cortisol. 

Don’t use CBD as a “natural” glaucoma remedy. CBD, or cannabidiol, is the non-psychotropic component of cannabis and hemp being touted as a magical cure-all. A study published last month in Investigative Ophthalmology & Visual Science shows it actually raised eye pressure in mice.

Eat a diet rich in fruits and vegetables, especially green, leafy ones. One study showed that people who ate more leafy vegetables have a 20 to 30 percent lower risk of developing glaucoma. Why? Nitrates in green vegetables can be converted to nitric oxide, which can improve blood flow and help regulate pressure inside the eye.

Don’t smoke. Smoking cigarettes increases the risk of glaucoma and has an overall negative impact on eye health.

Maintain a healthy body weight. People with a higher body mass index (BMI) are at increased risk for diabetes, and having diabetes puts people at risk of glaucoma. Having a too low BMI is also associated with increased glaucoma risk.

“Patients are often surprised to hear they have glaucoma because they do not have symptoms. Glaucoma is a progressive and devastating condition that shows no symptoms until vision loss has already occurred. Glaucoma cannot be prevented, but with early detection and treatment it can be controlled. We are happy to answer any questions you may have and address any concerns in order to preserve your eyesight.” --Ashley Hamblin, O.D.
