Intraocular pressure

At the glaucoma screening, the intraocular pressure measurement (tonometry) is used and the optic disc is assessed. This examination helps to determine whether intraocular pressure has increased and there is a suspicion of glaucoma.

This is how intraocular pressure increases

Our eye is governed by an intraocular pressure produced by the constant influx of aqueous humour. This aqueous humour flows from the posterior into the anterior ocular chamber; there, it is conducted from the eye into the bloodstream. If this balance of influx and outflow is disturbed, internal pressure can rise, and this may be an indication of glaucoma.

Chronically increased pressure does not trigger any symptoms, but damages the optic nerve significantly. That is why this examination is so important in preventing damage to the optic nerve in advance. Screening should take place from the age of 40.
