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.
In most cases of glaucoma, fluid cannot exit the eye properly through the trabecular meshwork — the drainage structure located at the angle between the iris and the cornea. This causes increased intraocular pressure (IOP), which over time restricts blood flow to the optic nerve and causes irreversible cell loss. Early detection and treatment are the only tools that prevent permanent vision loss from glaucoma. Without an eye exam, most patients would never know they have it.
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.
In most cases of glaucoma, there is no eye pain, no redness, and no visible change in vision until significant optic nerve damage has occurred. Loss of peripheral vision — the first measurable sign — is often not noticed by patients without a visual field test. This is why regular eye exams and IOP testing are critical for anyone with risk factors for glaucoma.
Vision lost to glaucoma is permanent and cannot be restored. Glaucoma treatment — including daily eye drops, minimally invasive glaucoma surgery (MIGS) such as Selective Laser Trabeculoplasty (SLT), or surgical procedures like trabeculectomy — works to lower intraocular pressure and slow or stop progression. Early detection and treatment change outcomes dramatically.
Family history of glaucoma — a parent or sibling diagnosed with glaucoma significantly elevates your personal risk
Age 40 or older — risk increases sharply after 60; the American Academy of Ophthalmology recommends regular eye exams for all adults at elevated risk
Previously elevated intraocular pressure (IOP) — flagged at a prior eye exam or by another eye doctor
African American, Hispanic, or Asian heritage — these groups face significantly higher risk for developing glaucoma and are diagnosed at earlier ages
Diabetes, high blood pressure, or cardiovascular disease — systemic conditions that affect blood flow to the optic nerve
Prior eye injury, eye surgery, or existing eye diseases — increases risk of secondary glaucoma
Long-term corticosteroid use — can increase intraocular pressure and damage the optic nerve over time
Sudden, severe pain in or around the eye may signal acute angle-closure glaucoma — a medical emergency requiring same-day treatment to prevent permanent vision loss.
Seeing rainbow-coloured halos around lights — especially at night — is a warning sign of elevated intraocular pressure and possible acute angle-closure glaucoma.
Loss of peripheral vision is typically the first measurable sign of glaucoma — and by the time patients notice it, significant optic nerve damage has already occurred. A visual field test can detect this early.
Sudden blurred vision, particularly when combined with eye pain or nausea, can indicate a rapid increase in intraocular pressure requiring immediate care.
Nausea accompanying sudden eye pain is a classic sign of acute angle-closure glaucoma. Call us immediately or go to an emergency eye care centre.
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.
Glaucoma does not currently have a cure, and vision already lost from optic nerve damage cannot usually be restored. However, early diagnosis and ongoing treatment can lower eye pressure, slow the progression of the disease, and help protect your remaining vision.
Your recommended examination schedule depends on your age, eye pressure, family history, existing diagnosis, and other risk factors. People at increased risk may need a comprehensive dilated eye examination every one to two years, while patients already diagnosed with glaucoma often require more frequent monitoring based on their doctor’s treatment plan.
An optometrist provides primary eye care and can examine, diagnose, monitor, and medically manage many glaucoma cases. An ophthalmologist is a medical doctor who specializes in eye diseases and can also perform laser procedures and eye surgery. Depending on the type and severity of glaucoma, the two providers may work together to coordinate your care.
Bring your current glasses or contact lens information, a list of all medications and eye drops you use, relevant medical and family history, previous eye records when available, and your insurance information. Because your pupils may be dilated, it is also helpful to bring sunglasses and arrange transportation if you are uncomfortable driving afterward.
Many medical insurance plans provide coverage for medically necessary glaucoma examinations, diagnostic testing, and treatment. Your exact benefits, copayments, deductibles, referral requirements, and covered medications depend on your individual plan. Contact your insurance provider or the Superior Eye Care team before your visit to confirm coverage.
Superior Eye Care provides a broad range of routine and medical eye care services in The Woodlands, including comprehensive eye examinations, diagnostic testing, vision correction services, and management of common eye conditions. Contact the office to confirm the availability of a specific service or to schedule an appointment.
