  2. Ocular tonometry - Wikipedia

    en.wikipedia.org/wiki/Ocular_tonometry

    The Perkins tonometer is a type of portable applanation tonometer, which may be useful in children, anesthetised patients who need to lie flat, or patients unable to co-operate with a sitting slit lamp examination, that yields clinical results comparable to the Goldmann. [8]

  3. Imbert-Fick law - Wikipedia

    en.wikipedia.org/wiki/Imbert-Fick_law

    Armand Imbert (1850-1922) and Adolf Fick (1829-1901) both demonstrated, independently of each other, that in ocular tonometry the tension of the wall can be neutralized when the application of the tonometer produces a flat surface instead of a convex one, and the reading of the tonometer (P) then equals (T) the IOP," whence all forces cancel each other.

  4. Intraocular pressure - Wikipedia

    en.wikipedia.org/wiki/Intraocular_pressure

    A patient in front of a tonometer. Intraocular pressure (IOP) is the fluid pressure inside the eye. Tonometry is the method eye care professionals use to determine this. IOP is an important aspect in the evaluation of patients at risk of glaucoma. [1] Most tonometers are calibrated to measure pressure in millimeters of mercury .

    Don’t move — or you’ll get wet! A New Jersey woman is accused robbing a bank using a water gun painted to look like a real pistol — and making off with $60,500. The incident happened in ...

  6. Goldmann Applanation Tonometer - Wikipedia

    en.wikipedia.org/wiki/Goldmann_Applanation_Tonometer

    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 ...

  7. Schiøtz tonometer - Wikipedia

    en.wikipedia.org/wiki/Schiøtz_tonometer

    The Schiotz tonometer consists of a curved footplate which is placed on the cornea of a supine patient. A weighted plunger attached to the footplate sinks into the cornea. A scale then gives a reading depending on how much the plunger sinks into the cornea, and a conversion table converts the scale reading into IOP measured in mmHg.

  8. Elwin Marg - Wikipedia

    en.wikipedia.org/wiki/Elwin_Marg

    In collaboration with R. Stuart Mackay, an electrical engineer at UC Berkeley, he completed a design of tonometer, a device for measuring intraocular pressure, in 1959. [3] This groundbreaking instrument was named Mackay-Marg Tonometer, after the developers.

  9. Type 99 tank - Wikipedia

    en.wikipedia.org/wiki/Type_99_tank

    The gun may be fired under computerized or manual control. The tank can carry 42 rounds including 22 in the autoloader. The rate of fire is 8 rounds per minute using the autoloader, and 2 rounds per minute with manual loading. [16] The Type 99A mounts an improved 125 mm gun, [17] with a new autoloader capable of firing 10 rounds per minute.
