Understanding and Preventing Glaucoma

Glaucoma is often called the "silent thief of sight" because it can slowly steal your vision without early warning signs. But with the right knowledge and proactive approach, you can take steps to protect your eye health. Let's explore the risk factors for glaucoma and the lifestyle choices that can help prevent this serious eye condition.

Understanding glaucoma risk factors

Glaucoma doesn't discriminate, but certain factors can increase your risk of developing this eye condition. Being aware of these risk factors can help you take appropriate preventive measures.

Risk factors for open-angle glaucoma

Open-angle glaucoma is the most common form of the disease. Key risk factors include:

• High eye pressure
• Family history of glaucoma
• Age (40+ for African Americans, 60+ for others)
• Thin cornea
• Suspicious optic nerve appearance

Other potential risk factors are:

• Severe nearsightedness
• Diabetes
• Eye surgery or injury
• High blood pressure
• Use of corticosteroids

Risk factors for angle-closure glaucoma

This less common form of glaucoma has its own set of risk factors:

• Age 40 and older
• Family history of glaucoma
• Farsightedness
• Eye injury or surgery
• East Asian or Inuit ethnicity

Risk factors for normal-tension glaucoma

Even with normal eye pressure, some people can develop glaucoma. Risk factors include:

• Cardiovascular disease
• Family history of glaucoma
• Low eye pressure
• Japanese ethnicity

Lifestyle choices to lower your glaucoma risk

While some risk factors are beyond our control, many lifestyle choices can help reduce your risk of developing glaucoma or slow its progression if you already have it.

Exercise for eye health

Regular physical activity can have a positive effect on your eye health:

• Aerobic exercise: Brisk walking, swimming, or cycling for 30-45 minutes, 3-4 times a week, can lower intraocular pressure and improve blood flow to the eyes.
• Strength training: Light weightlifting is generally safe, but avoid heavy lifting that might increase eye pressure.
• Yoga: While some yoga poses can be beneficial, avoid inversions that might elevate eye pressure.

Diet and nutrition for glaucoma prevention

What you eat can play a role in protecting your eyes from glaucoma:

1. Antioxidant-rich foods: Dark, leafy greens, colorful fruits and vegetables, and berries can support eye health.
2. Mediterranean diet: This heart-healthy eating plan may also benefit your eyes.
3. Dietary supplements: Some supplements show promise in supporting eye health, including:
   • Coenzyme Q10 (CoQ10)
   • Flavonoid anthocyanins
   • Ginkgo Biloba extract
   • Magnesium
   • Vitamin B3

Other lifestyle factors to consider

• Sleep position: Sleeping with your head elevated 20-30 degrees may help lower eye pressure.
• Avoid smoking: Smoking has been associated with faster glaucoma progression and higher eye pressure.
• Limit caffeine intake: Excessive caffeine consumption may temporarily increase eye pressure.
• Protect your eyes from sun exposure: Wear sunglasses and hats when outdoors.
