During the screening examination for glaucoma, intraocular pressure measurement (tonometry) is used and the optic disc is assessed. The examination can determine whether the intraocular pressure has increased and glaucoma (glaucoma) is suspected.

How does elevated intraocular pressure develop?

There is intraocular pressure in the eye, which is caused by a constant inflow of aqueous humor. The aqueous humor flows from behind into the anterior chamber of the eye and is then discharged from the eye into the bloodstream. If the balance of inflow and outflow is disturbed, the intraocular pressure may increase and this may be an indication of glaucoma. Screening should be performed from the age of 40.
