Intraocular pressure between 12 and 22 is generally considered
normal. How low the pressure can be, in order for it to be considered
safe, depends on a patient to patient basis. Values that are considered
normal can cause damage in certain patients
(“normal tension
glaucoma”)
In contrast, some patients might have higher than normal pressure
without any obvious damage to the optic nerve. This condition is
called
ophthalmic hypertension
and requires close monitoring in
case it converts to glaucoma, whilst might even require prophylactic
treatment with drops.
It depends on the type of glaucoma.
Primary open angle glaucoma, which is the most common type, does
not give any initial symptoms. As said earlier, the sense of weight or
pressure does not actually mean high intraocular pressure.
The rare form of acute closed angle glaucoma is accompanied with
unbearable pain, forcing the patient to seek immediate help from an
ophthalmologist.
