Vision viewpoints: Expert answers on glaucoma

Glaucoma is sometimes called the "silent thief of sight" because it can worsen without many noticeable symptoms, potentially leading to vision loss if left untreated. We asked Dr. Chad Overman, Delta Dental of Iowa’s medical expert for DeltaVision®, to explain what glaucoma is, how it can be detected and the steps you can take to help protect your vision.

Q: What is glaucoma, and why is it called the "silent thief of sight?"

Dr. Overman: Glaucoma is essentially increased pressure inside your eye that causes the nerve fibers to die, which results in loss of your peripheral vision (your ability to see along the sides or up and down without turning your head). It is considered “silent” because it typically does not hurt, and you rarely notice an early loss of peripheral vision.

Q: What are the early signs and symptoms of glaucoma?

Dr. Overman: Unfortunately, there rarely are obvious signs of early-onset glaucoma.  The only way to find it is to be tested by your eye doctor.

Q: What tests are involved in checking for glaucoma during an eye exam?

Dr. Overman: Tonometry (pressure test) and visual fields along with retinal photographs are the typical tests involved for glaucoma.

Q: Can glaucoma be prevented, or are there steps people can take to reduce their risk?

Dr. Overman: Regular eye doctor visits are by far the best prevention.

Q: What treatment options are available for glaucoma, and how effective are they in preserving vision?

Dr. Overman: In the United States, we normally start with eyedrops to control the pressure. One or more drops may be needed and are usually enough to control the pressure, at least initially. In Europe, they start with surgery first (lasers or scalpel are two forms of surgery) and then add drops later. Both treatment approaches can be effective.

Q: How can people with glaucoma maintain their quality of life and protect their remaining vision?

Dr. Overman: Fortunately, glaucoma is usually a slow-progressing disease, and people can avoid vision loss until they have had it for a long time. Starting treatment early and staying diligent by keeping your regular vision appointments will help prevent vision loss.

Your eye care professional will recommend your preventive visit schedule based on your specific eye care needs and medical history.

3 refreshing mocktail tips for a sober night in

Mocktails have become increasingly popular, offering a delicious and fun alternative to alcoholic beverages. Not only are they perfect for those who choose not to drink, but they can also be a healthier option. If you want to mix up your own booze-free beverage but don’t know where to start, here are a few tips to craft refreshing and healthy mocktails.

1. Swap juice and sparkling water for coconut water

Fruit juices and sparkling waters are classic mocktail mixers, but they can be packed with sugar and acid that may lead to cavities. For a healthier alternative, try coconut water. Not only does it add a tropical vibe to your drink, but it also delivers some oral health benefits.

Two mouth-friendly benefits:

• Coconut water contains potassium, a nutrient that helps your body use teeth-strengthening calcium.
• The electrolyte-boosting benefits of coconut water improve your hydration, which is essential to a healthy mouth.

2. Fresh mint for the win

Add a few fresh mint leaves to your mocktails to add flavor and fun presentation. As a bonus: The herb is also great for your oral health.

Two mouth-friendly benefits:

• Mint naturally kills bacteria in your mouth that can cause cavities and bad breath.
• Chewing on fresh mint leaves boosts the saliva in your mouth, which helps clear away leftover food particles and bacteria. 

3. Green tea gives an antioxidant boost

Mocktails may lack alcohol, but that doesn’t mean they are automatically healthy. Many mocktails are high in sugar and calories, but using green tea as a base for your mocktail offers both flavor and health perks, especially for your smile.

Two mouth-friendly benefits:

• Green tea packs powerful antioxidants that can help reduce inflammation that may lead to gum disease.
• Helps reduce bad breath and fights harmful bacteria.

Embrace mocktails as part of your oral health routine

Although mocktails can be a healthier alternative to alcoholic drinks, it's still important to practice moderation and maintain good oral hygiene. Brushing your teeth twice daily, flossing daily and visiting your dentist for twice yearly preventive visits are essential for a healthy smile.
