Full Answer

IOP is the tissue pressure within the eye, established by the balance between the production of fluid in the eye and the drainage of the fluid from the eye, states EyeHealthWeb. The normal eye pressure range for healthy individuals is between 10 to 20 millimeters of mercury. Minor changes in IOP are not uncommon and are caused by inflammation of the eye after infection or trauma, anatomical problems, medication use, genetic factors, exercise, fluid intake, and even alcohol or caffeine consumption.

Ocular hypertension is generally signified by pressure of 21 mmHg or higher, states All About Vision. Causes for ocular hypertension are essentially the same as glaucoma. Symptoms include too much fluid production in the eye, insufficient drainage of the eye fluid, certain medications such as steroids, eye trauma or other eye conditions. Ocular hypertension increases the risk of glaucoma or vision loss. A doctor may prescribe eye drops to help reduce high eye pressure, or he may recommend other glaucoma treatment measures to treat high eye pressure.
