Elevated pressure in the eye is called ocular hypertension. It is defined as having an intraocular pressure reading higher than 21 mm Hg, notes eMedicineHealth. This can occur if there is an overproduction of aqueous humor or there is slow drainage of aqueous humor through the trabecular meshwork due to this small drain channel not functioning properly.

Some other causes for ocular hypertension are medications, such as steroids. In some cases, an eye injury can affect the balance of the aqueous humor. Similarly, rare eye conditions, such as corneal arcus, may lead to an increase in intraocular pressure. Corneal arcus is a condition in which there can be clouding around the edge of cornea.

Although an elevated intraocular pressure can occur in anyone, there are groups of people that may be at a higher risk for this condition, including those over the age of 40, have diabetes, or are nearsighted, notes EyeSmart. Additionally, a family history of either glaucoma or ocular hypertension also may be a predisposing risk factor for this condition.
