Primary open-angle glaucoma (POAG), the most common type of glaucoma, develops like many chronic illnesses—slowly and painlessly. In addition, many POAG patients tend to suffer from other chronic illnesses, like hypertension, heart disease, or diabetes. Researchers continue to investigate potential connections and similarities between glaucoma and other chronic conditions.* 

How has research shown a connection?

Two studies have found an association between POAG and chronic conditions:

• One study published in 2010 looked at 75,000 POAG patients’ medical records and found nearly 50% had hypertension and 30% had diabetes or elevated blood level cholesterol. 
• A 2016 study used data from the National Health Insurance Database and found POAG patients had a higher risk of ischemic heart disease (coronary heart disease) than those without POAG. 

Is glaucoma more than an eye disease?

With a clear connection between POAG and chronic conditions, some researchers believe glaucoma may be more than just an eye disease. It could be a vascular disease—a disease associated with blood vessels (arteries and veins). POAG may develop from poor blood circulation or abnormal blood vessels, which would make it more than an unexplainable eye disease. If this is true, lifestyle changes that benefit the heart could also help your vision. 

What lifestyle changes may help support my vision?

Managing your intraocular pressure (IOP) is key to preventing vision loss in POAG. Some changes and lifestyle habits that may help include:

• Quitting smoking
• Following a well-balanced, nutritious diet
• Avoiding caffeine and limiting alcohol
• Exercising frequently
• Seeing an eye doctor regularly who specializes in glaucoma

If you have questions about starting or making any of these changes, speak to your doctor for individualized recommendations.
