What is Glaucoma and Why Early Screening Matters
Glaucoma is a group of eye conditions characterized by elevated intraocular pressure that can damage the optic nerve. Untreated, it can lead to irreversible peripheral vision loss.
Early screening identifies subtle optic nerve changes before symptoms appear, allowing timely referral to a glaucoma specialist. Understanding glaucoma’s mechanisms highlights why routine eye exams are essential.
Understanding Optic Nerve Health
Elevated eye pressure can harm the optic nerve. Early detection is critical to preserve vision.
According to the American Academy of Ophthalmology, glaucoma is a leading cause of blindness, underscoring the importance of regular screening.
Causes of Glaucoma
Glaucoma develops when intraocular fluid pressure damages the optic nerve. Common causes include:
- Impaired drainage of aqueous humor through the trabecular meshwork
- Excessive production of intraocular fluid
- Genetic predispositions affecting nerve resilience
These pressures gradually reduce peripheral vision, often without pain or early warning signs.
Types of Glaucoma
Each type requires evaluation by an eye care specialist.
Why Early Detection is Critical
Screening allows optic nerve changes to be identified before vision loss occurs. Early detection ensures timely referrals to glaucoma specialists, maximizing the chance to preserve daily function and quality of life.
Who is at Risk?
Certain factors increase glaucoma risk:
Age 60+
Family history of glaucoma
Diabetes, hypertension, or cardiovascular disease
Previous eye injury or long-term corticosteroid use
The National Eye Institute recommends regular exams for people with these risk factors.
How Age and Family History Influence Risk
Older age can reduce eye drainage efficiency, increasing pressure. Family history may triple the risk due to genetics.
Medical Conditions That Increase Risk
Chronic conditions like diabetes and hypertension may weaken optic nerve resilience through vascular effects.
What to Expect During Your Eye Exam at Fox Run Eye Care
At Fox Run Eye Care, glaucoma risk assessment is part of every annual eye exam.
Tests Performed
- Icare Tonometry (non-puff): Measures intraocular pressure
- Optos Imaging: High-resolution retinal images
- Slit Lamp Examination: Evaluates optic nerve appearance
If risk factors are detected, patients are referred to a trusted glaucoma specialist for additional testing such as OCT or visual field testing.
How Long Does the Exam Take?
A comprehensive exam usually lasts 20–30 minutes, covering all screening steps appropriate for our practice.
Why Choose Fox Run Eye Care in Portsmouth, NH?
We provide personalized care with early detection of risk factors, using advanced imaging and pressure measurement tools.
Technologies Used
- Icare Tonometry (non-puff)

When We Refer Out
We do not perform OCT, visual field testing, or treat glaucoma directly. If further evaluation is needed, patients are promptly referred to a glaucoma specialist.
Annual Exams Beyond Glaucoma
Routine exams also help detect genetic, age-related, or systemic conditions such as diabetes, high blood pressure, or high cholesterol through eye health.
Annual check-ups with Optos imaging allow comparison year-over-year to detect subtle changes early.
