Tonometry: Measuring Eye Pressure and More

When working with Tonometry, a clinical test that assesses the pressure inside the eye. Also known as eye pressure measurement, it helps eye doctors detect problems early and decide on treatment plans.

Tonometry’s main job is to gauge Intraocular Pressure, the fluid pressure that fills the eye’s front chamber. Higher than normal levels can signal Glaucoma, a leading cause of irreversible vision loss. Because the damage from glaucoma often occurs without obvious symptoms, doctors rely on regular pressure checks to catch trouble before it hurts sight. The relationship is simple: tonometry measures pressure; elevated pressure raises glaucoma risk.

Why Context Matters: Pachymetry and Visual Field Testing

Pressure numbers alone don’t tell the whole story. Pachymetry, a test that measures corneal thickness, refines tonometry results. A thicker cornea can make pressure readings appear higher than they truly are, while a thin cornea might hide dangerous pressure spikes. By pairing tonometry with pachymetry, eye care professionals get a clearer picture of real risk.

Another piece of the puzzle is Visual Field Testing, a series of assessments that map a patient’s peripheral vision. Even if pressure looks normal, subtle vision loss on a field test can reveal early glaucoma damage. Combining these tools—tonometry, pachymetry, and visual field testing—creates a robust screening strategy that catches disease at its earliest stage.

Beyond glaucoma, tonometry helps monitor ocular hypertension, assess the effectiveness of eye drops, and guide surgical decisions. Whether you’re a patient curious about why your doctor wants a pressure check, or a clinician looking for a quick refresher on the test’s impact, the articles below cover everything from the basics of measurement techniques to the latest research on pressure‑lowering therapies.
