What Is Glaucoma? Understanding the Silent Thief of Sight
Glaucoma is a group of eye diseases that damage the optic nerve — the critical connection between your eyes and your brain. Because the optic nerve carries every visual signal your brain receives, damage to it causes irreversible vision loss. And the most alarming part: most people experience no noticeable symptoms in the early stages.
Glaucoma is a leading cause of blindness worldwide. In most cases, glaucoma occurs when fluid builds up inside the eye and cannot drain properly. That fluid increases pressure within the eye, and over time, elevated eye pressure restricts blood flow to the optic nerve and destroys nerve fibers. Once those fibers are gone, they cannot be restored — which is why early detection matters so much.
Glaucoma cannot be cured, but with the right monitoring and treatment in Houston, its progression can be slowed significantly. The goal of glaucoma care is protecting the vision you have.
Most patients with open-angle glaucoma experience no pain and no visual changes until significant optic nerve damage has already occurred. The only reliable way to detect glaucoma early is through a thorough eye exam that includes direct optic nerve assessment — not just a vision check.
There are several forms of glaucoma, and each behaves differently. Understanding which type you have determines how it is monitored and treated.
Open-Angle Glaucoma
The most common type, accounting for the majority of cases in the United States. The drainage angle between the iris and cornea remains open, but the drainage system inside the eye becomes partially blocked over time. Fluid drains too slowly, eye pressure rises gradually, and because this happens painlessly and without symptoms, it is often called the "silent" form of glaucoma.
Angle-Closure Glaucoma
Occurs when the drainage angle becomes narrow or closes suddenly. This can cause acute glaucoma — a rapid spike in eye pressure accompanied by severe eye pain, headache, nausea, blurry vision, and halos around lights. Acute angle-closure is a medical emergency. If you experience these symptoms suddenly, call us immediately or go to the nearest emergency room.
Normal-Tension Glaucoma
In this less common form, damage to the optic nerve occurs even when the intraocular pressure (IOP) remains within the statistically normal range. This is why glaucoma evaluation goes far beyond measuring eye pressure — optic nerve appearance and visual field testing are equally important parts of the diagnostic picture.
Risk Factors and Symptoms of Glaucoma
Early glaucoma is almost always asymptomatic. Knowing your risk factors is the most reliable way to catch it before significant damage occurs. If any of the following apply to you, schedule a glaucoma evaluation — do not wait for symptoms to appear.
Risk Factors for Glaucoma
Schedule an evaluation if any of these apply- Family history of glaucoma — having a parent or sibling with glaucoma significantly increases your risk
- Age 40 or older, especially if African American, Hispanic, or Asian
- Elevated eye pressure identified during a previous eye exam
- History of eye injuries or previous eye surgery, including cataract surgery
- Long-term use of corticosteroid medications
- Diabetes or high blood pressure — conditions that affect blood flow to the optic nerve
- Previous diagnosis of early glaucoma or ocular hypertension
Symptoms of Glaucoma to Watch For
Most appear only after significant damage has occurred- Gradual loss of peripheral vision(side vision) in one or both eyes
- Tunnel vision in advanced stages
- Blurry vision
- Halos around lights, particularly at night
- Sudden changes in your vision without apparent cause
Severe eye pain, headache, nausea, blurry vision, and halos around lights together can signal acute angle-closure glaucoma — a medical emergency. Call (281) 477-7811 immediately or go to the nearest emergency room.
Many patients develop glaucoma with no risk factors at all. The only reliable way to know your status is regular eye exams with a provider who evaluates your optic nerve directly — not just your visual acuity.
How We Diagnose Glaucoma at Our Willowbrook Eye Center
Diagnosing glaucoma requires more than measuring eye pressure. At our Willowbrook clinic, Dr. Mathukutty conducts a multi-point glaucoma evaluation that looks at several factors together — giving us a complete picture of your optic nerve health, drainage angle structure, and eye pressure pattern.
Tonometry
Eye Pressure MeasurementTonometry measures the intraocular pressure (IOP)
inside the eye. Elevated eye pressure is the primary risk factor in most glaucoma cases. We use non-contact and applanation tonometry methods depending on the patient's presentation.
Elevated pressure alone does not confirm glaucoma — and normal pressure does not rule it out. This is why tonometry is just the starting point of a full evaluation, not the conclusion.
Visual Field Testing
Peripheral Vision MappingThe visual field test
maps your peripheral and central vision to identify any blind spots or areas of loss. It is one of the most important tools for detecting early glaucoma and tracking progression over time.
Patients with confirmed glaucoma typically repeat this test at regular intervals — every 3 to 6 months in many cases — to monitor whether the condition is stable or advancing.
Optic Nerve Imaging (OCT)
Structural Nerve AssessmentOptical coherence tomography (OCT) produces a detailed cross-section image of the optic nerve head and the nerve fiber layer around it. This allows us to detect structural changes to the optic nerve before significant vision loss occurs
— often identifying glaucoma at a stage where intervention is most effective.
OCT is one of the most valuable tools in modern glaucoma management, giving us objective measurements we can compare visit to visit.
Gonioscopy
Drainage Angle ExaminationGonioscopy uses a specialized lens to visualize the drainage angle between the iris and the cornea. This examination identifies if the drainage angle is open, narrow, or closed — information that directly determines which type of glaucoma you have and how it should be managed.
Without gonioscopy, it is impossible to correctly classify the type of glaucoma or select the right treatment pathway. This step is often skipped in routine eye exams.
A Complete Diagnostic Picture — Not Just One Number
Together, these four evaluations give Dr. Mathukutty a clear picture of your optic nerve health, drainage angle structure, and eye pressure pattern. Based on the findings, she will discuss your glaucoma status and the appropriate next steps — whether that is ongoing monitoring, prescription eye drops, or a referral for further intervention. You can also learn more about individual diagnostic services, including our intraocular pressure test and visual field testing, on their dedicated pages.
Glaucoma Treatment Options in Houston
Glaucoma treatment is focused on lowering eye pressure to a level that protects the optic nerve from further damage. The specific approach depends on the type of glaucoma, the stage of the disease, and how your eyes respond to treatment.
Medicated Eye Drops
For most patients, the first line of treatment involves prescription medicated eye drops
designed to reduce eye pressure. These drops either decrease the amount of fluid produced inside the eye or improve drainage through the drainage angle.
Consistent daily use is critical — treatment may require long-term adherence, and our team will review how to use drops correctly to avoid side effects. Skipping doses or stopping without guidance can allow eye pressure to rise and damage to progress.
Laser Procedures
Laser procedures can improve drainage in certain types of glaucoma. Two primary options are used depending on the type of glaucoma:
- Selective Laser Trabeculoplasty (SLT) — a minimally invasive option commonly used for open-angle glaucoma that targets the trabecular meshwork to help fluid drain more efficiently
- Laser Iridotomy — used for angle-closure cases to create a new drainage pathway through the iris, relieving pressure caused by a blocked or narrow angle
Glaucoma Surgery and Surgical Referral
When eye drops and laser procedures are insufficient to lower the pressure to a safe level, glaucoma surgery may be recommended. Procedures such as trabeculectomy
or minimally invasive glaucoma surgery (MIGS)
create new drainage pathways inside the eye.
As optometrists, Dr. Mathukutty and our team manage glaucoma non-surgically and co-manage surgical cases
with trusted ophthalmology partners when a surgical procedure becomes the appropriate step. You remain under our care throughout.
As a licensed therapeutic optometrist with glaucoma specialist certification, Dr. Mathukutty manages glaucoma medically — including prescribing and adjusting eye drops, ordering and interpreting diagnostic imaging, and coordinating laser or surgical referrals when needed. Most glaucoma patients, especially in early and moderate stages, do not need to visit a hospital-based ophthalmology group for routine management.

Answers to the questions patients most often ask about glaucoma care, diagnosis, and what to expect at our Willowbrook clinic.
In Texas, licensed therapeutic optometrists who hold a glaucoma specialist certification from the Texas Board of Optometry are authorized to diagnose and medically manage glaucoma. Dr. Sharon Mathukutty holds this certification and has managed glaucoma patients across Houston for over two decades.
For cases that require surgical intervention, we co-manage with ophthalmology partners and remain involved throughout your care — so you always have a consistent provider who knows your history.
A standard comprehensive eye exam checks your visual acuity, refractive error, and general eye health. A glaucoma evaluation goes further — it includes tonometry to measure eye pressure, gonioscopy to examine the drainage angle, OCT imaging of the optic nerve, and a visual field test to map your peripheral vision.
Not every routine eye exam includes all of these. If you have risk factors for glaucoma, specifically ask for a full glaucoma evaluation when you schedule.
No. Normal-tension glaucoma causes optic nerve damage even when intraocular pressure remains within the normal range. This is why a thorough glaucoma evaluation looks at the optic nerve directly — not just the pressure reading.
Relying on eye pressure alone can miss a significant percentage of glaucoma cases. Optic nerve imaging (OCT) and visual field testing are equally important parts of the diagnostic picture.
Most patients already diagnosed with glaucoma are seen every three to six months, depending on disease stability and treatment response. Patients at elevated risk with no current diagnosis are typically evaluated annually.
Dr. Mathukutty will recommend a monitoring schedule based on your specific situation after your initial evaluation. Schedules are adjusted over time as your condition evolves or stabilises.
Glaucoma cannot be cured, and vision lost to it cannot be restored. However, with consistent treatment and monitoring, progression can be slowed significantly in most patients.
The key is catching it early — before substantial peripheral vision loss has occurred. This is the entire purpose of regular eye exams for at-risk patients in Northwest Houston and across Harris County.
Sudden severe eye pain, headache, nausea, blurry vision, and halos around lights can indicate acute angle-closure glaucoma — a medical emergency. Call our clinic immediately at (281) 477-7811 during business hours.
If we are closed, go to the nearest emergency room without delay. Acute angle-closure can cause permanent vision loss within hours if left untreated.
Most medical vision insurance plans cover glaucoma evaluation and management as a medical visit — separate from a routine vision exam. We accept most major insurance plans.
