Intraocular Pressure - Measurement

Measurement

Intraocular pressure is measured with a tonometer as part of a comprehensive eye examination.

Measured values of intraocular pressure are influenced by corneal thickness and rigidity. As a result, some forms of refractive surgery (such as photorefractive keratectomy) can cause traditional intraocular pressure measurements to appear normal when in fact the pressure may be abnormally high.
