To assess the presence and magnitude of a
phoria or a strabismus (tropia). The cover test assesses the presence or
absence of motor fusion. When motor fusion is present (i.e., when there is
no strabismus), the cover test determines the magnitude of the demand placed
on a patient’s fusional vergence system.

Determines the direction and the magnitude
of a phoria or tropia but does not differentiate a phoria from a tropia.
Differentiates between a phoria and a tropia
and determines if a tropia is alternating or unilateral. The cover part of
the cover-uncover test differentiates phorias form tropias by determining
the position of the visual axis of each eye when both eyes are open to view
the target. If the patient has a phoria, each visual axis will be aligned
with the target when both eyes are open. If the patient has a tropia, one
visual axis will be aligned with the target and the other visual axis will
be misaligned with the target when both eyes are open. During the
cover-uncover test, only the unoccluded eye is observed to determine the
position of its visual axis.
The uncover part of the cover-uncover test
differentiates alternating tropias from unilateral tropias (constant right
or constant left tropias). A patient with an alternating tropia is able to
keep either the right or the left visual axis aligned with the target when
both eyes are open. A patient with a unilateral tropia habitually fixates
with one eye when both eyes are open, and only fixates with the troping eye
when the fixating eye is occluded. The examiner observes the eye that is not
covered by the occluder.
