Key Takeaways
- Glaucoma often progresses without warning, which is why routine eye exams are essential for early detection.
- Recognizable glaucoma symptoms usually appear only after permanent vision damage has already begun.
- Eye pressure and glaucoma are closely linked, so checking intraocular pressure is a critical part of every exam.
- Knowing how to reduce eye pressure through medical and lifestyle measures supports long-term vision health.
- Everett & Hurite offers comprehensive glaucoma screening and treatment across Pittsburgh, PA, and surrounding areas, making it easier to find a trusted glaucoma specialist near you.
What Glaucoma Is and Why Early Detection Matters
Glaucoma is a group of eye conditions that damage the optic nerve, often due to elevated pressure inside the eye. According to the Glaucoma Research Foundation, more than 3 million Americans have glaucoma, but only about half of them know it. It is one of the leading causes of irreversible blindness in the United States.
The biggest challenge with glaucoma is its silence. Most types do not cause pain or noticeable vision loss until the disease has reached an advanced stage. By that point, damage to the optic nerve cannot be reversed. A routine eye exam is the most effective way to catch glaucoma early and protect long-term vision.
Common Glaucoma Symptoms (and Why They Are Easy to Miss)
Many people expect a serious eye condition to come with obvious warning signs. With glaucoma, that is rarely the case. The National Eye Institute notes that early open-angle glaucoma, the most common form, often has no symptoms at all.
When glaucoma symptoms do appear, they can include:
- Gradual loss of peripheral or side vision
- Tunnel vision in later stages
- Patchy blind spots in central or side vision
- Sudden eye pain, headache, nausea, and blurred vision in acute angle-closure glaucoma
- Halos around lights in some cases
Because the most common form is so subtle, regular professional screening is the only reliable way to know what is happening inside the eye.
How Routine Eye Exams Screen for Glaucoma
A routine eye exam includes several tests designed to spot the early changes of glaucoma. Together, these tests give a complete picture of optic nerve health, eye pressure, and visual function.
Tonometry: Measuring Intraocular Pressure
Tonometry measures intraocular pressure, the pressure inside the eye. Because eye pressure and glaucoma are closely connected, this measurement is a key part of every comprehensive exam. Elevated pressure does not always mean glaucoma is present, and some patients develop glaucoma with normal pressure, which is why tonometry is just one piece of the puzzle.
Optic Nerve Evaluation and Imaging
Eye doctors examine the optic nerve directly using a dilated exam and often with high-resolution imaging tools such as optical coherence tomography (OCT). These tools can pick up subtle thinning of the nerve fiber layer years before vision changes appear.
Visual Field Testing
A visual field test checks peripheral vision, which is usually the first area glaucoma affects. By comparing results over time, the eye doctor can detect small changes that signal early disease.
Gonioscopy and Pachymetry
For patients at higher risk, additional tests like gonioscopy (examining the drainage angle) and pachymetry (measuring corneal thickness) help fine-tune the diagnosis and treatment plan.
Who Should Be Tested for Glaucoma?
Anyone can develop glaucoma, but certain groups are at higher risk. The American Academy of Ophthalmology recommends more frequent screening for:
- Adults over 60
- People of African, Hispanic, or Asian descent who face a higher risk for certain glaucoma types
- Anyone with a family history of glaucoma
- Patients with diabetes, high blood pressure, or migraine
- People with very high or very low eye pressure
- Patients with previous eye injuries or long-term steroid use
For these patients, even a 'normal' exam result should be revisited regularly. Early baselines are valuable because they make later changes easier to detect.
How to Reduce Eye Pressure and Protect Your Vision
Lowering intraocular pressure is the cornerstone of glaucoma treatment. A glaucoma specialist may recommend one or more of the following approaches to help patients understand how to reduce eye pressure:
- Prescription eye drops: The most common first-line treatment for glaucoma.
- Oral medications: Sometimes added when drops alone are not enough.
- Laser therapy: Procedures like selective laser trabeculoplasty (SLT) improve drainage.
- Surgical options: Including minimally invasive glaucoma surgery (MIGS) for select patients.
Lifestyle habits also play a supportive role. Regular aerobic exercise, a balanced diet, careful management of diabetes and blood pressure, and avoiding head-down positions for extended periods can all help. Patients should always discuss specific lifestyle questions with their eye doctor.

Frequently Asked Questions
How do I find a glaucoma specialist near me?
Everett & Hurite has glaucoma-trained ophthalmologists at multiple locations across western Pennsylvania, eastern Ohio, and northern West Virginia. Patients can choose the office closest to home and request an evaluation online or by phone.
How do I find an eye specialist near me for a routine glaucoma screening?
Patients can search by city or use the locations page on the Everett & Hurite website to find the nearest office. Each location offers comprehensive eye exams that include glaucoma screening, so patients do not have to travel far for high-quality care.
How often should I be screened for glaucoma?
Most adults should have a comprehensive eye exam every one to two years. Patients over 60, or those with a family history or other risk factors, may need annual screening or more frequent monitoring as recommended by their eye doctor.
Is glaucoma hereditary?
Family history is one of the strongest risk factors for glaucoma. Having a parent or sibling with the condition significantly increases the risk, which is why family members of patients with glaucoma should be screened regularly even if they feel fine.
