    This image is of the angle of the eye as seen through a slit lamp. It is labelled as Grade 4 according to Van Herick's Grading system. The Van Herick's technique compares the depth of the peripheral anterior chamber with the cornea thickness, usually written as a fraction [ 6 ] however, it can also be expressed as a ratio (see table 3). [ 5 ]

  4. Glaucoma - Wikipedia

    en.wikipedia.org/wiki/Glaucoma

    Of the different types of glaucoma, the most common are called open-angle glaucoma and closed-angle glaucoma. [7] Inside the eye, a liquid called aqueous humor helps to maintain shape and provides nutrients. The aqueous humor normally drains through the trabecular meshwork. In open-angle glaucoma, the draining is impeded, causing the liquid to ...

    en.wikipedia.org/wiki/Snellen_chart

    A Snellen chart is an eye chart that can be used to measure visual acuity.Snellen charts are named after the Dutch ophthalmologist Herman Snellen who developed the chart in 1862 as a measurement tool for the acuity formula developed by his professor Franciscus Cornelius Donders.

    Mean deviation (MD): Derived from the total deviation and represents the overall mean departure from the age-corrected norm. [18] A negative value indicates field loss, while a positive value indicates that the field is above average. A P value is provided if the global indices are abnormal. It provides a statistical representation of the ...

  7. Anterior chamber angle - Wikipedia

    en.wikipedia.org/wiki/Anterior_chamber_angle

    The anterior chamber angle is a part of the eye located between the cornea and iris which contains the trabecular meshwork. The size of this angle is an important determinant of the rate aqueous humour flows out of the eye, and thus, the intraocular pressure. The anterior chamber angle is the structure which determines the anterior chamber depth.

  8. Field of view - Wikipedia

    FOV both eyes Vertical FOV Angle of view can be measured horizontally, vertically, or diagonally. The field of view (FOV) is the angular extent of the observable world that is seen at any given moment. In the case of optical instruments or sensors, it is a solid angle through which a detector is sensitive to electromagnetic radiation.
