Since glaucoma has no side effects early on, it is essential for people with a family history of risk factors for glaucoma to get tested. The following tests diagnose glaucoma:
Tonometry: measures the pressure inside the eye (intraocular pressure or IOP)
Ophthalmoscopy (dilated eye exam): examines the shape and color of the optic nerve
Perimetry: measures your field of vision
Gonioscopy: checks the angle where the iris meets the cornea
Pachymetry: determines the thickness of the cornea to better evaluate eye pressure.
