The cover test is a measurement of eye posture (or eye alignment). The test is performed in two steps. First, the clinician covers an eye with a hand or paddle and looks for movement of the fellow eye. The cover paddle is then removed, and the clinician looks for movement of the previously covered eye. This step is called the cover-uncover test.

Use the cover/uncover test to assess for heterotropias. Use the alternate cover test to assess for the total amount of deviation. This amount minus any heterotropia is the amount of heterophoria. 4. Intraocular pressure. Goldmann applanation tonometry is the gold standard and should be used in the clinic whenever possible.

The cover-uncover test is generally performed first. The cover-uncover test is useful to identify a tropia and differentiate it from a phoria. The test is done by using an opaque or translucent occluder to cover one eye. The occluder is held in front of the eye for a few seconds and then removed. When the fixing eye is occluded, the examiner.

The next test is a cover uncover test. This is a that test is performed to determine if there is a heterophoria or phoria, which is a latent strabismus or misalignment that is only present when binocular fusion is suspended or interrupted. This test is performed in the same manner as the single cover test except that attention is turned to the.

The cover-uncover test is done first to determine if a patient has either a phoria or a tropia. The alternating cover test, on the other hand, is used to measure the magnitude and direction of a deviation, regardless of whether it is a phoria or a tropia. 3. Unilateral Cover Test (UCT) Purpose and Setup.


Uncover Test Signs MedSchool

The Cover-Uncover Test This test is based on evoking a fixational eye movement. In nearly all cases of ocular misalignment, one eye fixates the target while the other deviates. If the fixating eye is covered, the deviating eye will move to fixate the target. This test requires good vision and an attentive patient.


Cover Test Signs MedSchool

The cover-uncover test is equivalent to the unilateral cover test but now the examiner observes the movements of the occluded eye when the cover is removed. If heterophoria is present, the covered eye moves to its heterophoric position and when uncovered, the eye makes a movement in the opposite direction to recover fixation..


Strab Intro

Cover test Cover-uncover test (a.k.a. alternate cover test) The cover-uncover test is used to differentiate if a misalignment is either a tropia or a phoria; that is, if the above cover test demonstrates no tropia, it is used to determine if a phoria (i.e. latent strabismus) is present. Large ones can be associated with asthenopia (i.e. eye strain) and diplopia.

Childhood Eye Examination AAFP

A cover-uncover test picks up manifest deviations (deviations that are always present). Procedure/Interpretation. The patient is asked to fixate on an object. A cover is introduced over the first eye for 1-2 seconds. As the eye is covered the uncovered eye is observed for movement. The cover is removed and again shift in fixation is noted.


Cranial Nerve IV (Trochlear Nerve) Palsy

Cover-uncover test for heterophoria: Cover one eye for 1-2 seconds. Uncover the eye and observe it for a shift in fixation. Refixation movement of the occluded eye on being uncovered: heterophoria; Alternating cover test: Cover one eye for several seconds , then cover the other eye, and begin alternating back and forth between the two.


Uncover iHeart

Uncover test: The uncover test detects heterophoria. After covering an eye for 2 to 3 seconds, the same eye movement is observed on uncovering. This test is done for both distance and near. Most examiners do the cover test and uncover test sequentially; hence, it is called the "cover-uncover" test.

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).
