Intraocular Pressure Test
in The Woodlands,
Spring TX
Your eye constantly produces fluid that must drain at the right rate to keep pressure stable. When drainage slows, intraocular pressure rises quietly — no pain, no warning. Over time, elevated IOP damages your optic nerve and causes permanent vision loss. At Superior Eye Care in The Woodlands, our glaucoma specialists provide advanced eye pressure testing to catch problems early, before damage begins.

What an Eye Pressure Test Actually Measures
Your eyes constantly produce a fluid called aqueous humor. As that fluid flows in, the same amount should drain out through a tiny channel near the iris. This balance keeps the pressure inside your eye — called intraocular pressure, or IOP — stable.
When that drainage slows or gets blocked, fluid builds up. Pressure rises quietly inside the eye. Over time, elevated IOP restricts blood flow to the optic nerve — the cable connecting your eye to your brain — and causes permanent damage. This is how glaucoma develops, often with no pain and no early warning signs at all.
How Eye Pressure Is Measured
The entire process takes less than a minute and causes no discomfort.
Eye drops are applied to numb the surface of your eye so you feel nothing during the test.
A small blue-light instrument gently touches the front surface of your eye for a fraction of a second.
The device records the exact intraocular pressure in millimeters of mercury (mmHg).
The process is repeated for your other eye. Each measurement takes only a few seconds.
Your doctor reviews your IOP readings and explains what they mean for your eye health.
No air puff. No discomfort. The modern tonometry method we use at our Woodlands location is more accurate and far more comfortable than the old air puff test.
Advanced Glaucoma Testing at Superior Eye Care
A single IOP reading only tells part of the story. At our Woodlands location, our glaucoma specialists combine multiple diagnostic tools to build a complete picture of your eye health and glaucoma risk.
Tonometry measures the pressure inside your eye using a small, non-invasive contact device. After numbing drops are applied, the instrument gently touches the cornea for a fraction of a second — giving us an accurate intraocular pressure reading in millimeters of mercury (mmHg). No air puff. No discomfort.
Learn about IOP TestingVisual field testing maps your peripheral vision to identify areas where glaucoma-related vision loss may have already begun. Since glaucoma attacks side vision first — long before central vision is affected — this test is one of the most important tools for catching early signs of optic nerve damage.
Learn about Visual Field TestingUsing optical coherence tomography (OCT), we capture high-resolution cross-sectional images of the optic nerve and nerve fiber layer at the back of the eye. This lets us detect structural changes caused by elevated IOP — often before any vision loss has occurred — and track the progression of the disease over time.
Learn about Retinal ImagingA full glaucoma evaluation combines tonometry, pachymetry (corneal thickness), visual field testing, and optic nerve imaging into one appointment. Our doctors review all results together to assess your true risk level and, if needed, create a personalised monitoring or management plan before vision loss has a chance to begin.

Glaucoma can affect anyone, but certain risk factors raise your chances of developing the disease significantly. If one or more of these apply to you, a glaucoma screening at our Woodlands location is strongly recommended — even if your vision feels completely normal right now.
Early detection is the only reliable way to prevent permanent vision loss. The earlier elevated IOP or optic nerve changes are identified, the more options you have to slow down the progression of the disease.

Dr. Sharon Mathukutty and Dr. Kimberly Kennedy are both licensed therapeutic optometrists and glaucoma specialists certified by the Texas Board of Optometry. Dr. Mathukutty graduated from the University of Houston College of Optometry in 2010 and has over 15 years of experience in glaucoma diagnosis and management. Dr. Kennedy is a Houston native and graduate of the University of the Incarnate Word Rosenberg School of Optometry, specialising in primary care optometry, glaucoma, and diabetic eye disease.
At our Woodlands location on Lake Woodlands Drive, both doctors combine advanced tonometry, optic nerve imaging, pachymetry, and visual field testing into a single, efficient glaucoma evaluation. Every result is reviewed together — not in isolation — so you leave with a clear picture of your eye health and a plan that fits your specific risk profile.
