Glaucoma is one of the leading causes of blindness worldwide, and what makes it especially concerning is how quietly it can develop. Often, people with glaucoma do not experience noticeable symptoms until the disease has already caused irreversible damage. For this reason, regular eye exams are essential for detecting glaucoma in its earliest stages, sometimes even before you realize anything is wrong.
Glaucoma is a group of eye conditions that cause damage to the optic nerve, most commonly due to elevated intraocular pressure (pressure inside the eye). There are different types of glaucoma, with open-angle glaucoma being the most common in adults. Since this disease can develop slowly and painlessly, many people are unaware they have it until significant vision loss has already occurred.
Routine eye exams are your best defense against undiagnosed glaucoma. During a comprehensive exam, your optometrist will:
• Measure intraocular pressure: Elevated pressure is a primary risk factor for glaucoma.
• Examine the optic nerve: The health and appearance of the optic nerve can reveal early signs of damage.
• Check your visual fields: Specialized testing detects subtle changes in your side vision that you may not notice yourself.
• Assess risk factors: Your doctor will consider your age, family history, race, and other factors that can increase your risk of glaucoma.
These tests are painless and can be performed as part of your routine annual or biannual eye exam.
Early detection allows for timely treatment, which can slow or stop the progression of glaucoma. Treatments may include prescription eye drops, laser therapy, or surgery - all designed to lower eye pressure and protect your vision. Regular exams are especially important if you have risk factors, such as being over age 40, a family history of glaucoma, African or Hispanic heritage, or certain medical conditions like diabetes.
Regular eye exams are the most effective way to protect your vision from the serious effects of glaucoma. Detecting the disease in its earliest stages gives you the best chance to slow its progression and preserve your eyesight for years to come.
