The Maddox rod test can be used to subjectively detect and measure a latent, manifest, horizontal or vertical strabismus for near and distance. The test is based on the principle of diplopic projection. [1] Dissociation of the deviation is brought about by presenting a red line image to one eye and a white light to the other, while prisms are ...
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).
The prism fusion range (PFR) or fusional vergence amplitude is a clinical eye test performed by orthoptists, optometrists, and ophthalmologists to assess motor fusion, specifically the extent to which a patient can maintain binocular single vision (BSV) in the presence of increasing vergence demands. Motor fusion is largely accounted to ...
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]
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.
The Lachish reliefs are a set of Assyrian palace reliefs narrating the story of the Assyrian victory over the kingdom of Judah during the siege of Lachish in 701 BCE. Carved between 700 and 681 BCE, as a decoration of the South-West Palace of Sennacherib in Nineveh (in modern Iraq), the relief is today in the British Museum in London, [1] and was included as item 21 in the BBC Radio 4 series A ...
A number of Bible scholars consider the term Worm ' to be a purely symbolic representation of the bitterness that will fill the earth during troubled times, noting that the plant for which Wormwood is named, Artemisia absinthium, or Mugwort, Artemisia vulgaris, is a known biblical metaphor for things that are unpalatably bitter.
