Living Well with Glaucoma: Comprehensive Management and Lifestyle Guide

Engaging in moderate aerobic exercise is beneficial for glaucoma management. Activities such as brisk walking, cycling, or light jogging can help lower IOP and improve ocular blood flow. Here’s the thing: when you exercise, your cardiovascular system gets a boost, and better blood circulation means that the optic nerve receives more nutrients and oxygen.

However, it is important to consider the type of exercise you choose. For instance, while aerobic exercises have been associated with a temporary reduction in IOP, intense weightlifting involving isometric holds or exercises like the downward dog yoga pose might temporarily spike eye pressure. These spikes could be risky, particularly for individuals with certain types of glaucoma or who are more vulnerable. If you enjoy yoga, consider modified poses that do not lower your head below your heart.

Many studies support the idea that moderate physical activity—not exceeding an hour of high-intensity training daily—can lead to better IOP management. Moreover, patients who engage in regular walking, with steps counting towards a more active non-sedentary lifestyle, have shown slower progression of visual field loss.

The position in which you sleep can play a role in your eye pressure control. Research shows that sleeping in a supine (lying down) position may increase IOP slightly, and sleeping with your head turned against the pillow can elevate it even more. Simple modifications, such as elevating the head of your bed or using a specialized pillow that minimizes direct pressure on your eyes, might help reduce these fluctuations.

For those with glaucoma, adjusting your sleeping habits could mean the difference between stable IOP and unnecessary pressure spikes, which in turn translates into better long-term vision preservation.

A balanced diet is another pillar of managing your glaucoma effectively. Foods rich in antioxidants, such as dark leafy greens, citrus fruits, and berries, can help neutralize free radicals that may contribute to optic nerve damage. Specifically, dietary nitrates found in greens can be converted into nitric oxide, a compound that helps dilate blood vessels and improve aqueous humor outflow, ultimately supporting lower IOP levels.

There is growing interest in the potential benefits of omega-3 fatty acids for ocular health. While their role in glaucoma management remains somewhat controversial, some studies suggest that moderate intake could help modulate blood flow and protect nerve cells. Just remember, balance is crucial: excessive omega-3 intake may not be beneficial for everyone.

In addition, while some evidence points to vitamins and herbal supplements offering protective effects, the best approach is to focus on a nutrient-rich diet. This means including plenty of fruits and vegetables, which not only support eye health but also enhance overall well-being.
