What Is Elevated Iop

Elevated intraocular pressure is a concern in people with ocular hypertension because it is one of the main risk factors for glaucoma. High pressure inside the eye is caused by an imbalance in the production and drainage of fluid in the eye (aqueous humor).

What is considered elevated IOP?

Normal eye pressure ranges from 12-22 mm Hg, and eye pressure of greater than 22 mm Hg is considered higher than normal. When the IOP is higher than normal but the person does not show signs of glaucoma, this is referred to as ocular hypertension.

What is dangerously high IOP?

An IOP reading higher than 22 mm Hg is considered ocular hypertension. High eye pressure significantly increases your risk of damage to the optic nerve, causing glaucoma and permanent vision loss.
