What Is Glaucoma? A Group of Eye Diseases That Damages the Optic Nerve
Glaucoma is a group of eye diseases that damages the optic nerve — the critical connection between your eyes and your brain. It is the leading cause of irreversible blindness worldwide, and glaucoma is often called the "silent thief of sight" because most patients have no symptoms of glaucoma until permanent vision loss has already occurred.
The most common type of glaucoma. The trabecular meshwork becomes partially blocked, causing intraocular pressure to rise slowly over years. There are no early symptoms — open-angle glaucoma is caught only through a comprehensive eye examination and IOP testing. Loss of peripheral vision is usually the first sign, and by the time it appears, significant optic nerve damage has already occurred.
Angle-closure glaucoma occurs when the angle between the iris and the cornea narrows or closes entirely, blocking fluid drainage. This can cause a sudden, acute increase in intraocular pressure. Symptoms — sudden eye pain, blurred vision, halos around lights, nausea — require same-day emergency care. Untreated angle-closure glaucoma leads to rapid, permanent vision loss.
In normal-tension glaucoma, the optic nerve is damaged even when intraocular pressure is within normal range — pointing to vascular vulnerability in the structures of the eye. Secondary glaucoma is driven by an underlying eye condition, trauma, or long-term medication use. Both types require precise early diagnosis and diligent long-term monitoring to prevent further vision loss.
Do You Need a Glaucoma Eye Exam?
Glaucoma is often called the "silent thief of sight" because most cases of glaucoma produce no pain and no visible symptoms until permanent vision loss has occurred. Open-angle glaucoma — the most common type — progresses silently for years. Early diagnosis through a comprehensive eye exam is the only reliable defence. Do not wait for symptoms to develop.
Frequently Asked Questions About Glaucoma
Is there a cure for glaucoma?
There is no cure for glaucoma. Vision lost to this condition is permanent. That honest answer is exactly why early detection changes outcomes so dramatically. When our doctors diagnose glaucoma before substantial damage has occurred, treatment helps manage progression and protect what you have. Schedule a comprehensive eye exam today if you carry any risk factors.
How often should I get a glaucoma eye exam?
If you have risk factors, an eye exam every year is the right starting standard. After a diagnosis is confirmed, most patients benefit from visits every six to twelve months so we can track changes in eye pressure and optic nerve health. The American Optometric Association supports regular eye exams as the standard for adults at elevated risk.
What's the difference between an optometrist and an ophthalmologist for glaucoma?
An ophthalmologist is a medical doctor who performs surgical procedures, including trabeculectomy, drainage implant placement, LASIK pre-consultation, and cataract surgery. An optometrist specializes in comprehensive eye examinations, diagnosis, and non-surgical management. Our doctors in The Woodlands, TX are certified glaucoma specialists and therapeutic optometrists, specifically licensed for this level of medical eye care. We manage everything non-surgical and coordinate with an eye specialist ophthalmologist partner when surgery becomes the appropriate step. If you've been referred to a facility like Mann Eye Institute, we can review your case and co-manage your care through the process.
What should I bring to my glaucoma appointment?
Bring your insurance card, a photo ID, and a current list of medications. Prior records from another eye clinic or ophthalmologist are especially useful — visual field results, OCT scans, and pressure readings help our doctors see how your eye health has changed over time. If you wear contact lenses or glasses, bring your current eye prescription as well.
Is glaucoma treatment covered by insurance?
In most cases, yes. Glaucoma diagnosis and management qualifies as a medical eye exam, billed to your medical insurance rather than a standard vision plan. We offer comprehensive eye care services at all three of our locations and accept most major medical insurance plans. Contact us today and our team will verify your benefits before your visit.
