What is ocular hypertension?
Answer:
There is a constant pressure of the fluid that fills the eye (called intraocular pressure) which allows the eye to maintain its shape and function.
In ocular hypertension, this pressure is above the normal levels (this isn't to be confused with the pressure of blood within the vessels supplying the eye).
It might not cause any problems in itself, but it should be closely monitored because it can indicate the development of eye problems such as glaucoma.
