Intraocular Pressure

 

Your eyes are filled with fluid (aqueous humor) that helps keep them inflated like a ball.
Normal intraocular pressure helps support the shape of the eye, which in turn supports the parts of the eye that help you see.

Intraocular pressure is carefully regulated by the balance between the production and the drainage of aqueous humor.

The normal pressure in the eyes can change during the day and differ from person to person. In healthy eyes, the fluids drain freely to keep the eye pressure steady.

There is a clinical procedure called Tonometry, It is a diagnostic test that measures intraocular pressure (IOP) and the normal range for intraocular pressure is about 10-20 mm HG.

When the fluid in the front of your eye doesn’t drain as well as it should, or your eye is producing too much fluid, pressure can get too high. This is known as ocular hypertension. It can lead to glaucoma, a group of eye diseases that causes blindness.

Glaucoma doesn’t cause pain, and you can have it for years without noticing any changes in your vision until end stage which can lead to vision loss.

So checking for high eye pressure can help you know early.
There are other types of glaucoma that occur even in normal intraocular pressure, this will be talked about subsequently.

Happy Glaucoma Week.
