Ophthalmic Scribe Certification (OSC) 2025 – 400 Free Practice Questions to Pass the Exam

The Cover Test is designed specifically to evaluate eye alignment and coordination when focusing on a visual target. During this test, one eye is covered while the other is observed for movement. If the uncovered eye has to move to fixate on a target when the cover is removed, this indicates that the eye was not properly aligned before the test, highlighting issues such as strabismus (misalignment of the eyes).

In contrast, the Confrontation Test assesses peripheral vision by having the examiner compare their visual field with that of the patient. The Ocular Motility Test involves tracking movements of the eyes in different directions but does not focus on fixation and eye alignment specifically in the same way the Cover Test does. Visual Field Screening evaluates the extent of the visual field but is not concerned with whether the eye needs to move to focus on a target. Thus, the Cover Test is the most appropriate choice for determining the need for eye movement to pick up a fixation target.
