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 ...
A cover test or cover-uncover test is an objective determination of the presence and amount of ocular deviation. It is typically performed by orthoptists, ophthalmologists and optometrists during eye examinations . The two primary types of cover tests are: the alternating cover test. the unilateral cover test (or the cover-uncover test).
Esophoria is an eye condition involving inward deviation of the eye, usually due to extra-ocular muscle imbalance. It is a type of heterophoria. Cause.

Suppose when testing each hypothesis , the test statistic we use is . If these 's are independent, then a test for can be developed by the following procedure, known as Šidák correction. Step 1, we test each of m null hypotheses at level . Step 2, if any of these m null hypotheses is rejected, we reject. H n u l l {\displaystyle H_ {null}}
