Final answer:
Ocular hypertension can occur when intraocular pressure (IOP) is higher than the normal range. Excessive intraocular pressures can lead to glaucoma and permanent optic nerve damage. Noncontact methods, like using a puff of air, can be used to measure and manage intraocular pressure.
Step-by-step explanation:
Ocular hypertension can occur when IOP (intraocular pressure) is higher than the normal range of 12.0 to 24.0 mm Hg.
Glaucoma is a condition that can result from the buildup of fluid pressure in the eye when the fluid circulation is blocked. Excessive intraocular pressures, such as ocular hypertension, can cause permanent damage to the optic nerve.
Measuring intraocular pressure involves exerting force on the eye and observing its response. Noncontact methods, such as using a puff of air, can help detect and control excessive intraocular pressures.
