What is the eye pressure monitor?
eye pressure monitor, known as a tonometer, is a device that measures intraocular pressure (IOP) to monitor and keep control of glaucoma. Glaucoma concerns a number of eye diseases that result in partially increased IOP. The high IOP is caused by excess eye fluid or an aqueous humor inside the eyeball. Routine eye tests and tonometer tests are the only way to ensure that the eye pressure remains at safe levels.
usually measures the eye pressure monitor in mercury millimeters (mm Hg) as well as the blood pressure monitor. The normal eye pressure should drop between 10 mm Hg and 21 mm Hg and high eye pressure, known as eye hypertension, is diagnosed when the eye pressure exceeds 21 mm Hg. Excess fluid may be the result of increased fluid production or reduced fluid drainage in the eye. This increased eye pressure can damage the optical nerve that transmits visual stimuli from the eye to the brain. Glaucoma can lead to a reduction in vision and finally, blindness, if untreated. These tonometers appllant orThey flatten part of the cornea and measure resistance. There are several types of tonometers of Applanation.
Contact tonomers are applens tonometers that require contact with the cornea. These can be unpleasant and frightening for children and require an eye anesthetic to be applied to the eyeball before the procedure, usually in the form of eyes. Therefore, the tonometers of the corneal complement are generally used only in the clinical environment by doctors.
patients can also monitor their condition at home by purchasing their own eyes monitor. The pressure monitor can be used by gently pressing the device against closed or partially closed lid to apply the eye up to pressure phosphen or swirling of COOB or light. It is at this point that the device deducts the eye pressure.
The third type of tomer uses instead of the device itself by inflating air to applay the eye. Because this method does not require contact with open or closed eye, carries the same risk of transmission of eye diseases as other types and is somewhat more comfortable. For these reasons, this type of tonomer is commonly used in the offices of optometrists and ophthalmologists as a quick and easy method of patients screening for glaucoma.
