What is the normal eye pressure?

During the eye test, the tonometer measure the pressure of the fluid around the cornea. In order to be considered a normal eye pressure, the measurement should be between 10 and 20 mmhg. Reading may vary according to the position of the body, time of day and factors such as medicine or fluid intake. Increased pressure can be a warning feature of problems, especially glaucoma.

The cornea of ​​the eye is filled with a thick liquid called water humor. This fluid helps keep the cornea curved and inflated. The eye constantly produces new water humor and releases old. The fluid pressure is measured by a tonometer that measures the amount of force needed to balance the corneal area. The thickness of the corneal can affect the results.

There are a number of ways to measure the eye pressure. Some tonometers include direct contact with the eye, which usually requires a local anesthetic and is considered to be a more reliable method. Several methods of non -contact methods include a tunuometer that pushes the air cloud on the cornea and measures the air strength when it intervenes. This style is good pRO children or people who are nervous about touching the machine.

tonometer measures the normal eye pressure in millimeters of mercury (Hg). The healthy range is from 10 to 20 mmHg, with an average of about 14 to 16 mmhg. The amount of pressure may vary throughout the day and may vary depending on the position of the body. Factors that usually affect general health, such as exercise, medicine or alcohol intake, can also affect the pressure of the eye.

Although the normal eye pressure usually increases with age, a significant increase or pressure difference in each eye may be warning symptoms for health problems. High pressure is often observed in glaucoma, although the disease can develop without it. Eye pressure above 21 mmHg can damage the optical nerve and can lead to blindness. If glaucoma is caught early, doctors can be able to slow this disease. However, once the eye is damaged, it is difficult to fix. That's why it is important to have regular koNormal for measuring normal eye pressure and timely problems.
