  2. Intraocular pressure - Wikipedia

    en.wikipedia.org/wiki/Intraocular_pressure

    Measured values of intraocular pressure are influenced by corneal thickness and rigidity. [5] [6] As a result, some forms of refractive surgery (such as photorefractive keratectomy) can cause traditional intraocular pressure measurements to appear normal when in fact the pressure may be abnormally high. A newer transpalpebral and transscleral ...

    The machine uses this value to correct for the effects of the cornea on measurement. [20] In a population based study in healthy children that compared non-contact IOP measuring tonometer, including ORA and CORVIS with a contact tonometer, GAT, which is a routine instrument for IOP measurement.

  4. Ocular hypertension - Wikipedia

    en.wikipedia.org/wiki/Ocular_hypertension

    For most individuals, the normal range of intraocular pressure is between 10 mmHg and 21 mmHg. [3] 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]

    Theoretically, average corneal rigidity (taken as 520 μm for GAT) and the capillary attraction of the tear meniscus cancel each other out when the flattened area has the 3.06 mm diameter contact surface of the Goldmann prism, which is applied to the cornea using the Goldmann tonometer with a measurable amount of force from which the IOP is ...

  6. Eye examination - Wikipedia

    en.wikipedia.org/wiki/Eye_examination

    Intraocular pressure (IOP) can be measured by tonometry devices. The eye can be thought of as an enclosed compartment through which there is a constant circulation of fluid that maintains its shape and internal pressure. Tonometry is a method of measuring this pressure using various instruments. The normal range is 10-21 mmHg.

  7. 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 ...

  8. Ocular hypotony - Wikipedia

    en.wikipedia.org/wiki/Ocular_hypotony

    Ocular hypotony is divided into statistical and clinical types. If intraocular pressure is low (less than 6.5 mm Hg) it is called statistical hypotony, and if the reduced IOP causes a decrease in vision, it is called clinical. [4]
