Maddox wing. The Maddox Wing is an instrument utilized by ophthalmologists, orthoptists and optometrists in the measurement of strabismus (misalignment of the eyes; commonly referred to as a squint or lazy eye by the lay person). It is a quantitative and subjective method of measuring the size of a strabismic deviation by dissociation of the ...
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 ...
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.
This x-intercept is also referred to as aligning prism or – in earlier times – as associated phoria when the subjective nonius method was used (sP 0) the slope of the curve near zero prism load; Fig. 3: Fixation disparity as a function of the forced vergence angle which is induced by base-in prisms and base-out prisms in front of the eyes.
Xylitol is used as a food additive and sugar substitute. Its European Union code number is E967. [3] Replacing sugar with xylitol in food products may promote better dental health, but evidence is lacking on whether xylitol itself prevents dental cavities. [4][5] In the United States, xylitol is used as a common sugar substitute, and is ...
The bases of a matroid characterize the matroid completely: a set is independent if and only if it is a subset of a basis. Moreover, one may define a matroid to be a pair , where is the ground-set and is a collection of subsets of , called "bases", with the following properties: [7][8] (B1) There is at least one base --.
Camps. 1/4 TF Highlander in '07 w/1st LAR, 3/4 in '06/'07, and many others over years. Large SVBIED at TCP Alpha 20070507. Mosul Air Base. Used by Romanian troops. [1] All UN sanctioned weapons were destroyed and FOB was transitioned to the Iraqi Ministry of Defense in 2009.
Orthonormal basis. In mathematics, particularly linear algebra, an orthonormal basis for an inner product space with finite dimension is a basis for whose vectors are orthonormal, that is, they are all unit vectors and orthogonal to each other. [1][2][3] For example, the standard basis for a Euclidean space is an orthonormal basis, where the ...
