    Glaucoma is diagnosed through a complete eye exam that includes 5 tests: tonometry for intraocular pressure, pachymetry for corneal thickness, ophthalmoscopy for optic nerve examination, perimetry for visual field assessment, and gonioscopy for measuring the anterior chamber angle. These tests help determine the presence and severity of glaucoma.

    A complete eye exam for glaucoma diagnosis typically includes five tests:[1]

    • Tonometry; to measure intraocular pressure
    • Pachymetry; to measure the thickness of the cornea
    • Ophthalmoscopy; to examine the optic nerve for damage
    • Perimetry; to assess the field of vision
    • Gonioscopy; to measure the eye’s anterior chamber angle
