  2. Fixation disparity - Wikipedia

    en.wikipedia.org/wiki/Fixation_disparity

    A fixation disparity is not constant within a certain observer, but can vary depending on the viewing conditions. If test prisms with increasing amount are placed in front of the observer’s eyes, the fixation disparity changes in the eso direction with base-in prisms and in the exo direction with base-out prisms (Fig. 3).

  3. Maddox rod - Wikipedia

    en.wikipedia.org/wiki/Maddox_rod

    The strength of the prism is increased until the streak of the light passes through the centre of the prism, as the strength of the prism indicates the amount of deviation present. The Maddox rod is a handheld instrument composed of red parallel plano convex cylinder lens , which refracts light rays so that a point source of light is seen as a ...

    en.wikipedia.org/wiki/Maddox_Wing

    Numbers and arrows should be seen clearly. Relaxation of accommodation can result in an increase in exophoria and a decrease in esophoria, leading to an inaccurate result; The examiner should check the function of the Maddox Wing Instrument before use; the septa can be easily bent, leading to the septa not covering the intended view.

  5. Exophoria - Wikipedia

    en.wikipedia.org/wiki/Exophoria

    Exophoria is a form of heterophoria in which there is a tendency of the eyes to deviate outward. [1] During examination, when the eyes are dissociated, the visual axes will appear to diverge away from one another. [2] The axis deviation in exophoria is usually mild compared with that of exotropia.

  6. Heterophoria - Wikipedia

    en.wikipedia.org/wiki/Heterophoria

    Heterophoria is an eye condition in which the directions that the eyes are pointing at rest position, when not performing binocular fusion, are not the same as each other, or, "not straight".

    en.wikipedia.org/wiki/Rassam_cylinder

    The Rassam cylinder is a cuneiform cylinder, forming a prism with ten faces, written by Neo-Assyrian king Ashurbanipal in 643 BCE. The 7th century BCE cylinder was discovered in the North Palace of Nineveh by Hormuzd Rassam in 1854, hence its name. It is located in the British Museum. [4] [1]

    Happily the context of 51 and 52, together with the base, mid-line, and smaller triangle area (which are given as 4 + 1/2, 2 + 1/4 and 7 + 1/2 + 1/4 + 1/8, respectively) make it possible to interpret the problem and its solution as has been done here. The given paraphrase therefore represents a consistent best guess as to the problem's intent ...

  9. Prism cover test - Wikipedia

    en.wikipedia.org/wiki/Prism_Cover_Test

    The prism cover test (PCT) is an objective measurement and the gold standard in measuring strabismus, i.e. ocular misalignment, or a deviation of the eye. [1] It is used by ophthalmologists and orthoptists in order to measure the vertical and horizontal deviation and includes both manifest and latent components. [1]
