  2. Intraocular pressure - Wikipedia

    en.wikipedia.org/wiki/Intraocular_pressure

    Ocular hypertension (OHT) is defined by intraocular pressure being higher than normal, in the absence of optic nerve damage or visual field loss. [ 13 ] [ 14 ] Ocular hypotension, hypotony, or ocular hypotony , is typically defined as intraocular pressure equal to or less than 5 mmHg.

  3. Ocular tonometry - Wikipedia

    en.wikipedia.org/wiki/Ocular_tonometry

    It is an important test in the evaluation of patients at risk from glaucoma. [1] Most tonometers are calibrated to measure pressure in millimeters of mercury , with the normal eye pressure range between 10 and 21 mmHg (13–28 hPa).

  4. Ocular hypertension - Wikipedia

    en.wikipedia.org/wiki/Ocular_hypertension

    Ocular hypertension is the presence of elevated fluid pressure inside the eye (intraocular pressure), usually with no optic nerve damage or visual field loss. [1] [2]For most individuals, the normal range of intraocular pressure is between 10 mmHg and 21 mmHg. [3]

  5. Ocular hypotony - Wikipedia

    en.wikipedia.org/wiki/Ocular_hypotony

    Normal IOP ranges between 10–20 mm Hg. [1] The eye is considered hypotonous if the IOP is ≤5 mm Hg (some sources say IOP less than 6.5 mmHg). [2] [3] Types.

    A normal range of vision. The same view with advanced vision loss from glaucoma. ... Intraocular pressure can sometimes reach 80 mmHg (11 kPa). It characteristically ...

  7. 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.

  8. Primary congenital glaucoma - Wikipedia

    en.wikipedia.org/wiki/Primary_congenital_glaucoma

    The diagnosis is clinical. The intraocular pressure (IOP) can be measured in the office in a conscious swaddled infant using a Tonopen or hand-held Goldmann tonometer. Usually, the IOP in normal infants is in the range of 11-14 mmHg. [7] Buphthalmos and Haab's striae can often be seen in case of congenital glaucoma. [citation needed]

    en.wikipedia.org/wiki/Spaceflight_Associated...

    In general populations IOP ranges between and 20 mmHg with an average of 15.5 mmHg, aqueous flow averages 2.9 μL/min in young healthy adults and 2.2 μL/min in octogenarians, and episcleral venous pressure ranges from 7 to 14 mmHg with 9 to 10 mmHg being typical.
