Where there are fluids, there’s pressure affecting them. We’re concerned with our blood pressure and the air pressure in our tires. Sometimes less apparent to eye patients is the pressure of the intraocular fluid in their eyes. When intraocular pressure exceeds...

Among the most important instruments in an ophthalmologist’s office is the tonometer, which measures the pressure of fluid within the eye. Most tonometers measure intraocular fluid pressure through applanation or direct contact with the cornea. Others simply rely on...

Taking a reading of a patient’s intraocular pressure is the first step in identifying the onset of glaucoma. High pressure in the eyes leads to high pressure upon the optic nerve, which damages the cells of those nerves and impedes the eyes’ ability to communicate...

One of the most important tasks any eye doctor has is to screen for glaucoma—the gradual loss of vision due to pressure on the optic nerve. Most of this pressure comes from an inability of the eye to drain intraocular fluid. Measuring intraocular pressure, or IOP,...
