How is glaucoma diagnosed?

Glaucoma can be diagnosed by using several clinical tests like tonometry (measuring the pressure of the eye), gonioscopy (visualizing the drainage angle) and most importantly, fundoscopy (visualizing the optic nerve).
Investigations such as visual field test for side vision, corneal thickness (pachymetry) are also done. Sometimes, optic nerve imaging is ordered (OCT) and at yet other times ultrasound biomicroscopy may be done.
