    Impression tonometry (also known as indentation tonometry) measures the depth of corneal indentation made by a small plunger carrying a known weight. The higher the intraocular pressure, the harder it is to push against and indent the cornea. For very high levels of IOP, extra weights can be added to make the plunger push harder. [14]

  9. Gonioscopy - Wikipedia

    en.wikipedia.org/wiki/Gonioscopy

    In ophthalmology, gonioscopy is a routine procedure that measures the angle between the iris and the cornea (the iridocorneal angle), using a goniolens (also known as a gonioscope) together with a slit lamp or operating microscope. [1] [2] Its use is important in diagnosing and monitoring various eye conditions associated with glaucoma.
