Glaucoma Screening: What It Is and Why You Should Get Checked

Glaucoma is the leading cause of irreversible blindness, but most people don’t notice any symptoms until the damage is already done. That’s why a quick screening can save your sight. In this guide we’ll walk through who needs a test, what happens during the exam, and how to make an appointment without hassle.

Why Glaucoma Screening Matters

Glaucoma damages the optic nerve, the part of the eye that sends visual signals to the brain. The damage starts slowly, often without pain or noticeable changes. Regular screening catches the pressure buildup early, giving doctors a chance to lower it before permanent loss occurs. If you’re over 40, have a family history of glaucoma, or belong to a high‑risk group (like people of African or Asian descent), the risk goes up and you should be screened more often.

Even if you feel fine, a simple eye pressure test—called tonometry—takes less than a minute and can reveal warning signs. Early treatment usually involves eye drops or laser therapy, both of which are far less invasive than surgery required for advanced disease.

How to Get Screened

Getting screened is easy. Most optometrists and ophthalmologists include glaucoma checks as part of a routine eye exam. Here’s what to expect:

• Schedule an appointment: Call your eye doctor or use an online portal. Ask specifically for a glaucoma screening if it’s not routine for your age group.
• Brief medical questionnaire: You’ll answer a few questions about family history, medical conditions, and any eye symptoms.
• Pressure measurement: A puff of air or a small probe touches the eye lightly to measure intra‑ocular pressure. It’s quick and painless.
• Optic nerve imaging: Many offices use a quick scan (OCT or fundus photo) to look at the nerve’s health.

If any results are abnormal, the doctor will discuss next steps, which might include more thorough testing or starting treatment right away. Don’t skip follow‑up appointments—keeping pressure under control is key.

Insurance usually covers the screening for adults over 40, and many community health centers offer low‑cost or free checks for high‑risk individuals. If cost is a concern, ask your provider about payment options before the visit.

Bottom line: a few minutes of your time now can prevent years of vision loss later. Make an appointment today, ask about glaucoma screening, and protect your sight for the future.
