Dr. Elham Ghahari shares facts about glaucoma

January is Glaucoma Awareness Month. Glaucoma is a disease of the optic nerve that can cause vision loss. It is the second leading cause of blindness in the U.S. and the leading cause of irreversible blindness worldwide.

Providers at UK Advanced Eye Care use multiple testing strategies to diagnose and track glaucoma.

We recently spoke with ophthalmologist Dr. Elham Ghahari about glaucoma and how UK HealthCare can help.

What is glaucoma and what causes it? 

Glaucoma is the leading cause of global irreversible blindness, and 111.8 million people worldwide will have glaucoma by the year 2040. 

The hallmark of glaucomatous damage is the loss of the optic nerve cells that leads to characteristic changes in the optic nerve head with concomitant visual field damage. Glaucoma cannot be cured, but it can be controlled and stabilized with proper treatment. 

Primary open-angle glaucoma is the most common form of glaucoma and is associated with several risk factors such as family history, African ancestry, other eye diseases such as diabetes or inflammation, past eye injury, and elevated intraocular pressure. 

Abnormally high eye pressure is the most important glaucoma risk factor because it is the only modifiable and effective target of the therapy for glaucoma. Although some forms of glaucoma develop even when the eye pressure is normal, the risk of abnormally high eye pressure increases with age. 

At what age should people become concerned about developing glaucoma and what are some risk factors? 

Early detection and intervention can help prevent vision loss from glaucoma, but most patients do not know they have the disease because it is generally asymptomatic in the early stages. A routine eye exam can identify the risk for glaucoma and early signs of the disease.

During an eye exam, glaucomatous optic nerve damage can be assessed by clinical examination of the optic nerve head and eye pressure can be checked. Risk of having abnormally high eye pressure as the most important risk factor for glaucoma increases with age. Therefore, glaucoma screenings are suggested beginning at age 40 and should continue after that in intervals suggested by your eye doctor (usually every 2-4 years.)  

What are some warning signs someone might be developing glaucoma?

There are usually no early symptoms of glaucoma, so screening exams are very important. Gradual dimming or weakening of the vision is sometimes reported. Some patients with acute glaucoma develop severe eye pain and rapid visual changes. 

How is glaucoma treated?  

The mainstay of current glaucoma treatment is eye pressure reduction using medications, lasers or surgery. Most glaucoma patients can be stabilized with prescription eye drops or in-office laser treatment.

Once the pressure is stabilized, it is important to continue regular follow-up to make sure the pressure remains low enough. Less frequently, glaucoma surgery may be required.  

How can UK HealthCare help glaucoma patients and what makes us the best resource for treatment? 

Glaucoma specialists at UK Advanced Eye Care use multiple testing strategies to diagnose and track glaucoma. Because the first damage from glaucoma often starts with changes only in the peripheral vision, many people do not become aware they have glaucoma until the disease is in an advanced stage. The UK HealthCare Glaucoma Service offers several minimally invasive procedure choices. Many of these procedures are quick outpatient surgeries with minimal recovery time and are often performed in conjunction with cataract surgery.
