If you’ve ever found yourself wondering, “Could I be at risk for glaucoma?” that question often comes from a real place of concern. Glaucoma is a leading cause of irreversible vision loss, and it often develops quietly, without noticeable symptoms in its early stages. Many people are surprised by a diagnosis because their vision felt fine until changes had already begun. Understanding what can increase your chances of developing glaucoma and staying consistent with eye exams gives you the opportunity to catch it early and protect your vision for years to come.
You are more likely to be at risk for glaucoma if you are older, have a family history, belong to specific ethnic groups, or have medical conditions like diabetes or high blood pressure. The only way to know for sure is to have a comprehensive eye exam that checks your eye pressure, optic nerve, and visual field.
At Southwest Eye Institute, our doctors use advanced testing to detect glaucoma early and create a personalized plan to protect your vision.
What Is Glaucoma and Why Does Risk Matter?
Glaucoma is not just one eye disease. It is a group of conditions that damage the optic nerve, the “cable” that carries information from your eye to your brain. In many cases, this damage is related to increased pressure inside the eye, called intraocular pressure.
When eye pressure stays too high for too long, it can slowly injure the optic nerve. Vision loss often starts in the side (peripheral) vision and can advance silently over many years. Since this damage cannot be reversed, your risk level is crucial. The earlier glaucoma is found and treated, the more vision can be preserved.
The Most Common Types of Glaucoma
Open-angle glaucoma
Open-angle glaucoma is the most common form in the United States. It develops slowly. Most people do not experience pain or notice vision changes until later on. Over time, side vision can diminish, potentially leading to tunnel vision if left untreated.
Angle-closure glaucoma
Angle-closure glaucoma is less common but more urgent. It occurs when the drainage angle in the eye suddenly becomes blocked. This can cause a rapid rise in eye pressure, accompanied by symptoms such as severe eye pain, headache, nausea, blurred vision, and halos around lights. Angle-closure glaucoma is a medical emergency. It needs immediate treatment to prevent permanent vision loss.
Am I At Risk for Glaucoma? Key Risk Factors
You may be at higher risk for glaucoma if one or more of these apply to you:
-
You are over age 60, or over 40 if you are African American
-
You have a parent, brother, sister, or child with glaucoma
-
You are African American, Hispanic/Latino, or of Asian or Japanese descent
-
You have diabetes, high blood pressure, or heart disease
-
You are very nearsighted or very farsighted
-
You have had an eye injury or eye surgery in the past
-
You have thin corneas or chronic eye inflammation
-
You use steroid medications, especially steroid eye drops, for a long time
Having risk factors does not mean you will definitely develop glaucoma. It does mean that regular comprehensive eye exams are essential for you.
How Is Glaucoma Found? (It Takes More Than a Quick Screening)
Glaucoma is diagnosed through a comprehensive eye exam, not just a simple “air puff” or vision test. At Southwest Eye Institute, a glaucoma evaluation may include:
-
Measurement of your eye pressure
-
Careful examination of the optic nerve
-
Visual field testing to check your side vision
-
Optical Coherence Tomography (OCT) to look at the nerve fiber layers
-
Review of your medical history and family history
Because early glaucoma usually has no symptoms, these tests are often the first sign that anything is wrong. That is why we recommend regular exams, especially if you are already aware of your higher risk.
Can I Lower My Risk of Vision Loss From Glaucoma?
There is no way to guarantee that you will never get glaucoma. However, there is a lot you can do to lower your risk of vision loss:
-
Keep up with scheduled eye exams, especially if you are in a higher-risk group
-
Take glaucoma eye drops exactly as prescribed if you are diagnosed
-
Work with your primary care provider to manage blood pressure, diabetes, and cholesterol
-
Protect your eyes from injury when you play sports or use power tools
-
Tell your eye doctor about any long-term steroid use, including inhalers or creams
Early detection and consistent follow-up are the best tools we have to prevent glaucoma-related blindness.
Glaucoma Treatment Options if You Are Diagnosed
If your doctor finds signs of glaucoma, treatment focuses on lowering eye pressure and protecting the optic nerve. Your plan will depend on the type and severity of your glaucoma. Options may include:
Prescription eye drops
Eye drops are often the first step. They work by helping fluid drain from the eye or by reducing the amount of fluid the eye produces. Many patients do well for years with drops alone when they are used consistently.
Laser therapy
Laser procedures, such as Selective Laser Trabeculoplasty (SLT), can improve fluid drainage inside the eye. SLT is often used for open-angle glaucoma and may reduce the need for daily drops in some patients.
Minimally invasive glaucoma surgery (MIGS)
MIGS procedures utilize tiny devices or stents to facilitate the easy flow of fluid out of the eye. They are typically performed at the same time as cataract surgery or as a next step when drops and laser treatment are insufficient.
Traditional glaucoma surgeries
For more advanced or complex cases, procedures like trabeculectomy or glaucoma drainage implants may be recommended. These surgeries create new drainage pathways to lower eye pressure more effectively when other options are insufficient.
Your doctor at Southwest Eye Institute will explain which options are appropriate for your type of glaucoma and your overall eye health.
iDose® TR: A Tiny Implant That Delivers Medicine Over Time
For some patients, one of the biggest challenges with glaucoma is remembering eye drops every day. iDose® TR is a tiny, FDA-approved implant that slowly releases glaucoma medication inside the eye over an extended period of time. It is placed during a short, microscopic procedure, often at the same time as cataract surgery. It is designed to help lower eye pressure continuously, rather than relying solely on daily drops.
Because the medicine is delivered directly where it is needed, iDose® TR can help provide more stable pressure control and may reduce the number of drops you need. It is not right for everyone, however, and it is currently used for certain types of open-angle glaucoma and ocular hypertension. Your doctor at Southwest Eye Institute will review your specific diagnosis, eye pressure goals, and current treatment plan to decide whether an option like iDose® TR could be a safe and effective part of your long-term glaucoma management.
When Should I Be Worried Enough to Call Right Away?
Call an eye doctor or seek urgent care immediately if you notice:
-
Suddenly, severe eye pain
-
Nausea or vomiting with eye pain
-
Halos around lights with blurred vision
-
A sudden loss of vision in one or both eyes
These can be signs of angle-closure glaucoma or another serious eye problem that needs same-day treatment.

FAQ: Am I At Risk for Glaucoma?
1. If glaucoma runs in my family, how often should I get checked?
If you have a close relative with glaucoma, especially a parent or sibling, it is wise to have a comprehensive eye exam at least every one to two years, or as recommended by your eye doctor. Earlier and more frequent exams may be advised if other risk factors are present.
2. Can I have glaucoma even if my eye pressure is normal?
Yes. Some people develop normal-tension glaucoma, where optic nerve damage occurs even though eye pressure is within the “normal” range. That is one reason why optic nerve exams and visual field tests are essential, in addition to pressure readings.
3. I do not have any symptoms. Do I still need a glaucoma exam?
Yes. Most people with early glaucoma feel fine and see well. By the time symptoms are apparent, permanent vision loss may have already occurred. Regular exams are the most effective way to detect glaucoma early.
4. Does having diabetes increase my risk of glaucoma?
Diabetes is a known risk factor for glaucoma. It can also raise the risk of other eye diseases, such as diabetic retinopathy. If you have diabetes, regular dilated eye exams are crucial.
5. What should I do if I am worried I might be at risk?
The best first step is to schedule a comprehensive eye exam with a doctor who regularly manages glaucoma. Please bring your medical history, a list of medications, and any family history of eye disease. Your doctor can then inform you of your risk level and suggest a follow-up schedule tailored to your specific situation.
