  2. 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.

  3. 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.

  4. Ocular tonometry - Wikipedia

    en.wikipedia.org/wiki/Ocular_tonometry

    When the area of a circle with diameter 3.06 mm (0.120 in) has been flattened, the opposing forces of corneal rigidity and the tear film are roughly approximate and cancel each other out allowing the pressure in the eye to be determined from the force applied.

    To convert a delta temperature from degrees Fahrenheit to degrees Celsius, the formula is {ΔT} °F = ⁠ 9 / 5 ⁠ {ΔT} °C. To convert a delta temperature from degrees Celsius to kelvin, it is 1:1 ({ΔT} °C = {ΔT} K).

  6. Aqueous humour - Wikipedia

    en.wikipedia.org/wiki/Aqueous_humour

    The internal wall of the canal is very delicate and allows the fluid to filter due to the high pressure of the fluid within the eye. [7] The secondary route is the uveoscleral drainage , and is independent of the intraocular pressure, the aqueous flows through here, but to a lesser extent than through the trabecular meshwork (approx. 10% of the ...

  8. 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 ...

  9. Kelvin - Wikipedia

    en.wikipedia.org/wiki/Kelvin

    The Celsius, Fahrenheit, and Rankine scales were redefined in terms of the Kelvin scale using this definition. [ 2 ] [ 7 ] [ 8 ] The 2019 revision of the SI now defines the kelvin in terms of energy by setting the Boltzmann constant to exactly 1.380 649 × 10 −23 joules per kelvin ; [ 2 ] every 1 K change of thermodynamic temperature ...
