Glaucoma can slowly damage your peripheral, or side, vision without causing pain or an obvious change in your central sight. Many people feel that they see well even as permanent optic nerve damage develops.
A comprehensive eye exam at Vogue Vision can identify glaucoma risk and early changes that a basic vision screening may miss. Regular exams matter because lost vision from glaucoma usually cannot be restored.
What Is Glaucoma?
Glaucoma is a group of eye diseases that damage the optic nerve, which carries visual information from the eye to the brain. Without care, this damage can cause permanent vision loss.
The most common form in the United States is open-angle glaucoma. It often develops slowly as fluid inside the eye does not drain as well as it should.
How Does Eye Pressure Affect Glaucoma?
High intraocular pressure, or IOP, raises the risk of optic nerve damage. Pressure builds when fluid inside the eye cannot drain at a healthy rate.
However, glaucoma can occur when eye pressure falls within a typical range. A pressure reading alone cannot confirm or rule out glaucoma. The optometrist must also assess the optic nerve and other findings.
Why Is the Optic Nerve Important?
The optic nerve sends signals from the retina to the brain so you can see. Glaucoma damages its nerve fibers, often affecting side vision first.
This damage cannot be repaired. Early care can often slow further damage and help protect the sight that remains.
Why Are There No Early Warning Signs of Glaucoma?
Open-angle glaucoma often has no early warning signs because it progresses slowly and usually affects peripheral vision first. Your brain may adjust to small gaps in side vision, making the change hard to notice.
Can You Have Glaucoma Without Symptoms?
Yes. You can have glaucoma without symptoms for years. Your central vision may remain sharp while the disease gradually narrows your visual field.
By the time someone notices trouble seeing objects to the side, avoiding obstacles, or driving, a large amount of optic nerve damage may already be present.
Does Glaucoma Ever Cause Sudden Symptoms?
Yes. Angle-closure glaucoma can cause sudden eye pain, blurry vision, headache, nausea, halos around lights, and a red eye. This is an urgent medical problem that requires immediate care.
Most discussions about symptom-free glaucoma refer to open-angle glaucoma, which is much more likely to progress quietly.
How Is Glaucoma Detected?
Glaucoma is detected through a complete eye exam that checks eye pressure, optic nerve health, peripheral vision, corneal thickness, and the eye’s drainage angle. No single test provides the full answer.
Your exam may include:
- Tonometry: Measures pressure inside the eye
- Optic nerve exam: Checks the nerve for signs of damage
- Visual field test: Looks for missing areas in side vision
- Optic nerve imaging: Records nerve and retinal tissue
- Pachymetry: Measures corneal thickness
- Gonioscopy: Examines the eye’s drainage angle
An eye pressure test by itself is not enough to detect every case of glaucoma. Optic nerve changes and visual field results help the optometrist form a more complete picture.
Vogue Vision’s complete eye care services include annual exams that check your prescription and take a deeper look at your eye health.
Who Should Be Screened and How Often?
Everyone should receive routine comprehensive eye exams, but people with glaucoma risk factors may need exams more often. Your optometrist can set a schedule based on your age, health history, family history, and past results.
Higher-risk groups include people who:
- Are over age 40
- Have a parent or sibling with glaucoma
- Have elevated eye pressure
- Have diabetes or certain vascular conditions
- Have severe nearsightedness
- Have had an eye injury
- Use steroid medicine for long periods
- Belong to a population with higher glaucoma risk
How Often Should Adults Get Glaucoma Checks?
Exam timing varies by age and personal risk. Many adults receive yearly eye exams, while an optometrist may recommend closer monitoring when pressure, optic nerve appearance, family history, or other findings raise concern.
Vogue Vision provides annual eye care at its Central Iowa locations in Des Moines, Clive, and Indianola.
Where Can I Get a Glaucoma Screening?
Vogue Vision checks for signs of glaucoma and other eye diseases during comprehensive eye exams for patients across Central Iowa.
Visit a Des Moines eye care location or schedule an eye exam at any Vogue Vision office. A routine appointment may help uncover changes that clear vision alone cannot reveal.
