APPLANATION Meaning and Definition

1. Applanation is a term commonly used in ophthalmology and optometry that refers to the measurement of the pressure within the eye. Specifically, it is the act of flattening or making a surface level by the use of pressure. In the context of assessing intraocular pressure, applanation is conducted by applying a force or pressure to the cornea, the transparent front part of the eye.

   The most common method of applanation is the Goldmann applanation tonometry, where a small, flat-tipped device called a tonometer is gently placed against the cornea to assess the amount of force required to flatten it. By comparing this force to a scale, the intraocular pressure can be determined, which is an important factor in diagnosing and managing various eye conditions, particularly glaucoma.

   Applanation is crucial in obtaining accurate and reliable intraocular pressure measurements, as it allows for consistent assessment across different patients and helps to ensure consistency and comparability in monitoring eye health. It provides valuable information for eye care professionals to evaluate and manage various eye conditions, allowing for appropriate intervention when necessary.

   Overall, applanation is a fundamental technique used in ophthalmology and optometry to assess intraocular pressure and assist in the diagnosis and management of various eye conditions, especially glaucoma.

Etymology of APPLANATION

The word applanation has its roots in the Latin language. It is derived from the Latin verb applicare, which means to apply. The noun form of this verb, applicatio, is used to describe the act of pressing or applying something flat against a surface.

In the context of medicine and optometry, the term applanation specifically refers to the measurement of intraocular pressure (pressure inside the eye) by applying an instrument or object to the cornea (the transparent front part of the eye). The process involves flattening or pressing the cornea in order to determine the pressure accurately. Hence, the word applanation is used to describe this technique due to its literal meaning of pressing or applying flat.

Plural form of APPLANATION is APPLANATIONS
