What causes glaucoma?

Elevated eye pressure is considered a major risk factor for developing glaucoma. Normal values ​​of the eye pressure are in the range of 8-21 mmHg. According to some statistics, upper normal value is 22 mmHg or even 24 mmHg. It should be noted that any increase in eye pressure does not necessarily mean that a person has glaucoma.  For example, people with ocular hypertension have a value of intraocular pressure over 21 mmHg with no visible glaucoma damage to the optic nerve or changes in the visual field, but have a slightly higher risk of developing glaucoma disease. But changes in the optic nerve and visual field can occur also in normal and reduced values ​​of eye pressure.
