Either BASE IN for an exodeviation (eye turned out), BASE OUT for an esodeviation (eye turned in), BASE UP for a hypodeviation (eye turned down) or BASE DOWN for a hyperdeviation (eye turned up). Steps: 1. The patient should be measured in primary position first and then in any other positions of gaze of concern.
This test is designed to assess the following: the limits of a patient's BSV. strength of binocular functions (control) of a heterophoria to determine if it is decompensating [5] fusional convergence with a base out prism. fusional divergence with a base in prism. vertical amplitude with base up and base down prisms.
If the patient saw a red line to the left and white light to the right, they are said to have exotropia or exophoria (crossed diplopia) in which base in (BI) prisms of increasing strength are used until the lines are superimposed. [5] Maddox rod test tutorial. Method for measuring vertical deviations:
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).
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 ...
I, and many others, have collectively begun to acknowledge the price tag—the shame, pain, and isolation—of being the so-called model minority and the lines it makes us draw within.
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).

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". This condition can be esophoria, where the eyes tend to cross inward in the absence of fusion; exophoria, in which they diverge; or hyperphoria, in which ...
