Eye pressure measurement, also known as intraocular pressure (IOP) measurement, is a test used to assess the pressure inside the eye. This measurement is crucial for diagnosing and monitoring conditions like glaucoma, which can lead to vision loss if not treated. The test is typically performed using a device called a tonometer, which gently touches the surface of the eye or uses a puff of air to measure pressure. During the procedure, the eye may be numbed with drops to ensure comfort. Regular eye pressure checks are important, especially for individuals at higher risk, such as those with a family history of glaucoma or other eye conditions. Early detection can help prevent serious complications.
