The Cover/Uncover Test is performed using an occluder to cover one eye at a time. The occluder is held in front of the eye for a few seconds and then removed. The examiner observes the recovery movement of the occluded eye after the cover is removed. This test helps determine which eye is deviating, whether it’s the right or the left, and the direction of the eye deviation, whether it’s away from the nose (exo), towards the nose, (eso) upwards (hyper), or downward (hypo). The amount of eye devia

The cover-uncover test is used to identify eye misalignments (strabismus) and deviations. It helps differentiate between tropias (manifest deviations) and phorias (latent deviations). By covering one eye and observing the movement of the uncovered eye, clinicians can detect if an eye is drifting inward, outward, upward, or downward. This test is crucial for diagnosing and monitoring conditions like strabismus and can be used to assess the effectiveness of treatments. How the Test is Performed: 1
