ntraocular pressure (IOP) is the fluid pressure of the aqueous humor inside the eye. In ophthalmology, tonometry is the measurement eye care professionals use to determine the fluid pressure inside the eye. IOP is an important aspect in the evaluation of patients with glaucoma. Most tonometers are calibrated to measure pressure in millimeters of Mercury (mmHg).
Physiology and measurementIntraocular pressure is mainly determined by the coupling of the production of aqueous humor and the drainage of aqueous humor mainly through the trabecular meshwork located in the anterior chamber angle.Intraocular pressure is measured with a tonometer.
Influencing factorsIntraocular pressure measurement is also influenced by corneal thickness and rigidity.

How does pilocarpine lower intraocular pressure?
by ocular fluid outflow
What does Intraocular pressures of 12mmHg mean?
Normal intraocular pressure is between 10 and 20 mmHg. I've also seen 15.5 +/- 2.75.
How will the obstruction of the canal of Schlemm will result?
It results in reduced intraocular pressure
What is the name of the procedure that is performed to check the intraocular pressure of the eye?
TONOGRAPHY
What does tonometry measure?
Tonometry measures intraocular pressure (i.e. checks for glaucoma).
Which test measures intraoculare pressure?
Tonometry is the test that measures intraocular pressure.
The semicircular canals provide drainage within the eye to control intraocular pressure?
False
Semicircular canals provide drainage within the eye to control intraocular pressure?
False
What is an applanation?
An applanation is a flattening of the cornea, especially by the application of pressure.
What helps maintain the intraocular pressure located in the anterior part of the eye?
Intraocular pressure is 16 mm Hg and helps to maintain the shape of the eyeball. Intraocular pressure is maintained by a jelly-like substance, called the vitreous humor, which is located in the posterior cavity of the eye. According to the eyeball's structure it appears in this order: cornea, anterior cavity, pupil, iris, lens, posterior cavity (containing vitreous humor).
What is the purpose of a goniotomy?
to clear the obstruction to aqueous outflow from the eye, which in turn lowers the intraocular pressure (IOP).
An increase of intraocular pressure is most likely to cause?
Ocular hypertension. If high eye pressure is not controlled it can lead to other conditions, like glaucoma.
