The pressure inside the eye is created by the flow and drainage of the aqueous fluid (the clear fluid inside the eye) from the anterior chamber into the trabecular meshwork. An increase in pressure can result when the drainage passages become clogged or blocked. This can cause pressure within the eye to increase and damage the optic nerve.

What can be done?

A procedure called Tonometry is used to measure internal pressure of the eye. If the pressure is too high, the person may be diagnosed with glaucoma. Prescription eyedrops may be used to lower the pressure, and in severe cases, surgery may be necessary.

Since abnormal pressures usually don’t cause symptoms, it’s very important to have the pressure checked regularly.
