APPLANATIO CORNEAE Meaning and
Definition
-
Applanatio corneae refers to a medical examination technique used to assess the intraocular pressure (IOP) of the eye. Specifically, it is a method to measure the IOP by applying gentle pressure to the cornea. This procedure is commonly performed during routine eye examinations and is an important diagnostic tool in identifying conditions such as glaucoma.
During applanatio corneae, an ophthalmologist or optometrist may use an instrument called a tonometer. This device consists of a small, flat, and smooth surface that is gently pressed against the central area of the cornea. The amount of force applied is then measured to determine the IOP. In some cases, an anesthetic eye drop may be used to minimize any potential discomfort during the examination.
The IOP measurement obtained through applanatio corneae is considered significant as it can help identify abnormal eye pressure levels, which may be indicative of certain eye conditions, primarily glaucoma. Elevated IOP can put strain on the optic nerve, leading to vision loss if left untreated.
Regular evaluation of the IOP using applanatio corneae is often recommended for individuals with suspected or known risk factors for glaucoma, such as increased age, family history, or certain medical conditions. By detecting and monitoring changes in IOP, early intervention and suitable treatment options can be implemented to manage the condition effectively.
