Augnþrýstinginn, also known as intraocular pressure (IOP), is the pressure exerted by the fluid inside the eye. It is a crucial factor in the diagnosis and management of various eye conditions, particularly glaucoma. The normal range for IOP is typically between 10 and 21 millimeters of mercury (mmHg). Elevated IOP can lead to optic nerve damage and vision loss if left untreated.

IOP is influenced by several factors, including age, ethnicity, and overall health. It can be measured using a variety of methods, such as tonometry, which involves applying a small amount of air or water to the cornea to measure the pressure. Other methods include applanation tonometry, which uses a flat surface to measure pressure, and non-contact tonometry, which uses infrared light to measure IOP without direct contact with the eye.

Managing IOP is essential for preventing or slowing the progression of glaucoma. Treatment options may include lifestyle modifications, such as reducing salt intake and maintaining a healthy weight, as well as medications like eye drops or oral medications. In some cases, surgical procedures may be necessary to lower IOP.

Regular eye examinations are crucial for monitoring IOP and detecting any changes that may indicate the need for intervention. Early detection and management of elevated IOP can help preserve vision and prevent further damage to the optic nerve.
