Glaucoma is called "the silent thief of vision" for a reason. It destroys peripheral vision so gradually — and so painlessly — that most people don't notice anything is wrong until significant, irreversible damage has already occurred. An estimated 3 million Americans have glaucoma, and roughly half of them don't know it. Annual comprehensive eye exams are the only reliable way to catch glaucoma before it steals vision you'll never get back.
What Glaucoma Actually Is
Glaucoma refers to a group of conditions that damage the optic nerve — the cable that transmits visual information from your eye to your brain. The most common type, primary open-angle glaucoma, is associated with elevated intraocular pressure that gradually compresses and damages nerve fibers over time. Because peripheral vision is lost first and the brain compensates by filling in visual gaps, patients often don't notice until the disease has progressed to the central field. By that point, the damage is permanent and substantial.
Normal-tension glaucoma is a particularly insidious variant where nerve damage occurs despite normal intraocular pressure — making it detectable only through careful optic nerve evaluation and visual field testing, not pressure measurement alone.
Are You at Higher Risk?
While anyone can develop glaucoma, certain factors significantly elevate risk:
- ◆Family history — first-degree relatives of glaucoma patients have a 5–10x higher lifetime risk
- ◆Age over 60 — risk increases significantly with age
- ◆African or Hispanic heritage — statistically higher rates of open-angle glaucoma
- ◆High myopia — nearsightedness of -6.00 or greater increases glaucoma risk 2–3x
- ◆Prior eye injury or surgery — including LASIK in some cases
How We Screen and Monitor Glaucoma
At Harnos Optometry, glaucoma screening is part of every comprehensive eye exam — we measure intraocular pressure, carefully evaluate optic nerve appearance, and assess corneal thickness (which affects pressure interpretation). For patients with risk factors or suspicious findings, we add visual field testing and OCT imaging of the optic nerve fiber layer, which can detect structural changes years before they affect your measurable vision.
Glaucoma is highly manageable when caught early — most patients maintain their vision for life with appropriate treatment. But that requires finding it first. If it's been more than a year since your last comprehensive eye exam, or if you have risk factors for glaucoma, please make your appointment at Harnos Optometry in New Paltz a priority.
