January is Glaucoma Awareness Month

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 the people with the disease do not know they have it. Once vision is loss to glaucoma, it can't be regained. During Glaucoma Awareness Month in January, the Arkansas Ophthalmological Society joins the American Academy of Ophthalmology in reminding the public that early detection and treatment can help protect your sight.

Glaucoma damages the optic nerve, which transmits visual information from the retina to the brain. Typically, the disease progesses 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 ophthalmologists – physicians who specialize in medical and surgical 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 are farsighted or nearsighted;
* 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 Ophthalmology, the journal of the American Academy of 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.
