Eye Pressure Test Print E-mail

Dr. Kennedy The eye pressure test is a standard eye test using a tonometer that determines the fluid pressure inside the eye. The test is called tonometry. Persistent Increased pressure within the eye is glaucoma, a potentially serious eye problem if not detected and treated promptly. It is recommended that adults over age 40 have tonometry for glaucoma every 3 to 5 years. The pressure inside the eye is measured from the outside. The pressure can be measured without anything touching the eye. The patient looks up close at an instrument that blows a small puff of air into the eye and then uses a special kind of sensor (like a tiny radar detector) to detect the amount of indentation that the air puff causes on the surface of the eye. This indentation is normal and only lasts for a fraction of a second. If patients need to have their eye pressure measured in a setting where this type of machine is not available (as in an emergency room), the pressure can be measured with an instrument resembling a pen, called a pen tonometer. An anesthetic is administered in the form of an eye drop and one end of the instrument is placed on the surface of the eyeball.
