Ophthalmic Tonometers

Definition : Measuring instruments designed to determine intraocular pressure. These instruments may use several different techniques: applanation, indentation, and noncontact (air puff) tonometry. Tonometers can be attached to a slit lamp, and portable and handheld devices are also available. Ophthalmic tonometers are mainly intended for assessing ocular hypertension (intraocular pressure between 10 and 24 mm Hg is considered normal), usually to screen patients for glaucoma.
