What is another term for the procedure used to measure eye pressure?

Tonometry is the precise term used to refer to the procedure that measures intraocular pressure (IOP) within the eye. This measurement is crucial for detecting conditions like glaucoma, where elevated pressure might lead to optic nerve damage. Various methods can be employed in tonometry, such as applanation tonometry or non-contact tonometry, but they all serve the same purpose of assessing eye pressure.

In contrast, visual acuity tests focus on measuring the clarity or sharpness of vision, using eye charts to determine how well a person sees at various distances. A slit-lamp examination employs a specialized microscope to evaluate the structures in the front of the eye, including the cornea, iris, and lens, but does not measure eye pressure directly. Refraction tests are designed to determine an individual's need for corrective lenses by evaluating how the eye bends light, but again, they do not provide information about intraocular pressure. Therefore, tonometry is the specific and appropriate term for measuring eye pressure.
