Vision viewpoints: Expert answers on glaucoma
Posted on January 2, 2025 in Healthy You
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.
