  2. Intraocular pressure - Wikipedia

    en.wikipedia.org/wiki/Intraocular_pressure

    Intraocular pressure laws follow fundamentally from physics. Any kinds of intraocular surgery should be done by considering the intraocular pressure fluctuation. Sudden increase of intraocular pressure can lead to intraocular micro barotrauma and cause ischemic effects and mechanical stress to retinal nerve fiber layer. Sudden intraocular ...

  3. Ocular tonometry - Wikipedia

    en.wikipedia.org/wiki/Ocular_tonometry

    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 ] The movement of the plunger is measured using a calibrated scale. [ 14 ]

  4. Ocular hypertension - Wikipedia

    en.wikipedia.org/wiki/Ocular_hypertension

    It is estimated that approximately 2-3% of people aged 52-89 years old have ocular hypertension of 25 mmHg and higher, and 3.5% of people 49 years and older have ocular hypertension of 21 mmHg and higher. [4] [5] Elevated intraocular pressure is an important risk factor and symptom of glaucoma. Accordingly, most individuals with consistently ...

  6. Schiøtz tonometer - Wikipedia

    en.wikipedia.org/wiki/Schiøtz_tonometer

    Schiøtz tonometer is an indentation tonometer, used to measure the intraocular pressure (IOP) by measuring the depth produced on the surface of the cornea by a load of a known weight. The indentation of corneal surface is related to the IOP.

  7. Aqueous humour - Wikipedia

    en.wikipedia.org/wiki/Aqueous_humour

    Maintains the intraocular pressure and inflates the globe of the eye. It is this hydrostatic pressure that keeps the eyeball in a roughly spherical shape and keeps the walls of the eyeball taut. Provides nutrition (e.g. amino acids and glucose) for the avascular ocular tissues; posterior cornea, trabecular meshwork, lens, and anterior vitreous.

  8. Eye examination - Wikipedia

    en.wikipedia.org/wiki/Eye_examination

    Pressure is applied to the cornea until the inner edges of two semicircular fluorescein mires come into contact, forming a continuous circle. The corresponding reading on the tonometer scale represents the IOP of the measured eye. Intraocular pressure (IOP) can be measured by tonometry devices. The eye can be thought of as an enclosed ...

  9. Normal tension glaucoma - Wikipedia

    en.wikipedia.org/wiki/Normal_tension_glaucoma

    Over many years, glaucoma has been defined by an intraocular pressure of more than 20 mm Hg. Incompatible with this (now obsolete) definition of glaucoma was the ever larger number of cases that have been reported in medical literature in the 1980s and 1990s who had the typical signs of glaucomatous damage, like optic nerve head excavation and thinning of the retinal nerve fiber layer, while ...
