Thanks
The range of normal eye pressure is between 10-21mmHg. This covers 95% of the population, with approximately 5% of the population having a higher ‘normal’ pressure than this.
High pressure in the eye is a risk factor for developing glaucoma (an asymptomatic disease that can lead to visual loss) but long term studies have shown that the majority of people with high pressure do not necessarily develop glaucoma. They do need monitoring for developing the early signs of glaucoma long term.
Conversely, many people with glaucoma have a normal pressure in the eye. Despite that, we know lowering eye pressure in these people further reduces the chances of glaucoma making worse. The correct eye pressure for these people is one where the glaucoma does not get worse. This requires monitoring and supervised treatment.

A great question.Glaucoma Australias answer is great in the majority of cases .Todays researchers have found raised pressure was the main cause of optic nerve damage,but we now know normal IOP can result in FIELD loss from Glaucoma.The causes are still a bit of unknown….. there are more than 8-10 types of Glaucoma !!!.Today,pressure measurement,cornal thickness ,race ,age family history all play a part in detection.My lastest advice is OCT scan of the optic nerve head and neural thickness is very diagnostic,request this test if in doubt .
