What is ocular hypertension?

Ocular hypertension occurs when the pressure inside the eye exceeds the range considered normal and is above 21 mm Hg.

The increase in intraocular pressure (progressive with age, although it can also be due to other pathologies or causes) is the main risk factor for developing glaucoma and, therefore, people with ocular hypertension are more susceptible to the disease. However, the two are different: ocular hypertension occurs when the intraocular pressure is high but the optic nerve is not damaged, while in the case of glaucoma the optic nerve is already damaged -with normal or high intraocular pressure- and this can cause the patient to notice loss of visual field and even loss of central vision in advanced cases of the pathology.
