What is intraocular pressure and how is it generated?

Intraocular pressure is the pressure on the eyeball formed by the internal structures of the eyeball, mainly the fluid structure.

The components that form intraocular pressure include: vitreous, aqueous humor, and lens.

Aqueous humor is the main component of intraocular pressure.

The pressure inside the eyeball, or intraocular pressure for short, is the equalized pressure exerted by the contents of the eye on the wall of the eyeball.

The intraocular pressure of a normal person is stabilized within a certain range to maintain the normal shape of the eyeball and the visual function of the eye. The main methods for measuring intraocular pressure are digital tonometry and tonometry. The eyeball is a closed spherical tissue, composed of the eyeball wall (the outer layer is the cornea and sclera, the middle layer is the uvea, composed of the iris, ciliary body and choroid, and the inner layer is the retina) and the refractive system (cornea, aqueous humor, lens and vitreous humor).

Normal intraocular pressure ranges:

Lower than normal.

Lower results for possible diseases: eyeball rupture, retinal detachment, choroidal detachment, corneal fistula, chronic iridocyclitis.

Higher than normal.

Diseases with high results: hyphema and glaucoma, acute angle-closure glaucoma, open-angle glaucoma, neovascular glaucoma, primary acute angle-closure glaucoma, chronic angle-closure glaucoma, glaucoma due to lens dislocation.

Many people have a better understanding of the eyes than Shenghong, but the intraocular pressure is not so clear.

1.First of all, intraocular pressure is the pressure inside the eyeball, which is referred to as ocular crest. It is the equalizing pressure exerted by the contents of the eye on the wall of the eyeball.

The intraocular pressure of normal people is stabilized within a certain range to maintain the normal shape of the eyeball and at the same time ensure the maximum optical performance of the refractive interstitium.

2.Secondly, the normal intraocular pressure ranges from 11 to 21 mmHg. Generally, venous pressure rarely changes, so the drugs that regulate intraocular pressure are to adjust the rate of production of aqueous humor and the resistance to discharge.

3.Finally, there are many ways to measure intraocular pressure, such as choosing a digital tonometry or tonometer measurement.

Precautions. It is necessary to measure the intraocular pressure regularly, and if the intraocular pressure does not match the normal value, it is necessary to go to the hospital for examination in time to prevent the appearance of glaucoma.

Question 1: What is intraocular pressure and what is the purpose of the test The pressure of the eye contents (aqueous humor, vitreous humor, lens) acting on the eye wall is called intraocular pressure (intraocular pressure) Under normal circumstances, the aqueous humor production rate, aqueous humor discharge rate and ocular content volume are in a state of dynamic equilibrium. The intraocular pressure of ordinary people in China is 10-21mmHg, and there are special instruments that can be used to measure intraocular pressure.

Question 2: What is intraocular pressure? How to measure high intraocular pressure is more common in glaucoma, the main symptom is a significant decrease in vision, accompanied by severe eye pain, headache, etc., according to typical symptoms, combined with the measurement of intraocular pressure, it is generally not difficult to diagnose, it is usually recommended to have two cups of 9-flavor pupil tea every day, which can speed up the absorption of aqueous humor in the eye, reduce the generation of aqueous humor, and help reduce intraocular pressure.

If necessary, surgery should be carried out as appropriate**, as for the diet, it should be low in fat and salt, high in vitamins, eat more crude fiber foods, etc., to keep the stool smooth.

Question 3: How to measure intraocular pressure? Recommendations:

Intraocular pressure is the pressure of the contents of the eyeball on the wall of the eyeball, the intraocular pressure measurement has a finger measurement, the stool imitation is just a general feeling, the intraocular pressure is high, touching the eyeball is as hard as the forehead, the normal intraocular pressure is roughly the same as the tip of the nose, the intraocular pressure is the same as the jaw, the general hospital has a special intraocular tonometer, there are contact and non-contact, there are many types, I will not introduce them one by one, the intraocular pressure is high, it will compress the optic nerve, resulting in depressed atrophy of the optic nerve, so that the vision decreases, that is, glaucoma, acute glaucoma accompanied by vomiting, Symptoms such as severe headache and chronic manifestations are progressive loss of vision.

Question 4: What is intraocular pressure and what is the purpose of the test? It's eye strain

Question 5: What is the focus of intraocular pressure measurement? I don't know what your question is about ...

The eyes I measured were the ones that looked at the machine without taking their eyes off it, and then the machine blew into my eyes. It is said that the principle is to use the air pressure from the blowing to indirectly measure the pressure in my eye.

The normal intraocular pressure size is 10 21 mmHg.

Hope it helps you :)

Question 6: Is there any easy way to test intraocular pressure? The simplest method, the hardness of the forehead, lips, nose tip.

When the intraocular pressure is normal, gently press the eyeball with your hand (close the valve), which should be as hard as the tip of the nose.

Question 7: What is the function of intraocular pressure test? Is it a necessary routine check-up? Please attach some information You may have dry eyes and inverted eyelashes.

Objective: To control the condition of patients such as glaucoma through intraocular pressure detection, which can effectively prevent eye diseases in patients with diabetes and hypertension.

Intraocular pressure testing is generally done under the guidance of an ophthalmologist. Before the test, you need to clean your eyes and keep your eyes relaxed during the test, and avoid blinking or moving your head. The test results will be recorded and become an important reference for doctors to judge eye health.

Intraocular pressure testing is generally carried out under the guidance of the Tong imitation ophthalmologist Zhan Ku. Before the test, you need to clean your eyes and keep your eyes relaxed during the test, and avoid blinking or moving your head. The test results will be recorded and become an important reference for doctors to judge eye health.

Intraocular pressure refers to the pressure inside the eyeball and is an important indicator of maintaining the shape and normal function of the eyeball. Normal intraocular pressure is generally between 10-21mmHg, and high intraocular pressure may be an early sign of eye diseases such as glaucoma. Therefore, the measurement of intraocular pressure is of great significance for the diagnosis and ** of eye diseases.
