What is glaucoma?

Glaucoma is a disease which is a major cause of blindness in many people. Glaucoma damages the optic nerve which transmits visual signals to the brain. In fact, the nerves that carry information from the retina to the brain stop working. The most important mechanism of this damage to optic nerve is increase in intraocular pressure.

What is meant by internal pressure of the eye? And what should be the pressure of the eye normal?

Measurement of internal eye pressure is of great importance in the diagnosis and treatment of glaucoma. This is because the increase in pressure is an important sign of the disease and this can be controlled and hence in this way blindness can be prevented.. It is necessary to measure it repeatedly to assess the success of the treatment.

Allah Almighty has created a system for feeding the inner parts of the eye. A water-like liquid is formed from the blood and enters the eye. It provides food to the inner parts of the eye and goes back into the blood. In the glaucomatic eyes there is obstruction in the way to return to the bloodstream. The liquid slowly begins to accumulate inside the eye in larger amounts. As a result, the internal pressure of the eye becomes higher than normal

The internal pressure of the eye is usually below 21 but in case of glaucoma it goes up; maybe to 50, 40 and sometimes up to 100. This pressure can be measured in different ways as seen in the pictures below::
