Final answer:
Tonometry testing, which includes Applanation, Indentation, and Rebound Tonometry, measures intraocular pressure to detect fluid imbalances in the eye that could indicate glaucoma, especially in individuals over 40 years of age.
Step-by-step explanation:
The three types of tonometry testing for fluid imbalance in the eye are Applanation Tonometry, Indentation Tonometry, and Rebound Tonometry. These tests measure intraocular pressure (IOP), which is crucial for diagnosing and managing conditions such as glaucoma. In Applanation Tonometry, a small force is applied to the cornea to flatten a small area, and the force required to achieve this flattening correlates with the IOP. Indentation Tonometry involves pressing a plunger against the eye to measure the degree of indentation, which reflects the eye's pressure. Rebound Tonometry measures the eye's resistance to a small, rebounding probe and does not require corneal contact.
These methods are essential for detecting high intraocular pressure, which, if left unmanaged, can lead to vision damage or loss. Regular monitoring is particularly recommended for individuals over 40, as they are at a greater risk of developing glaucoma. Understanding and choosing the appropriate tonometry technique is important for accurate pressure measurement and effective glaucoma management.
