Which test evaluates binocular vision and eye coordination?

The cover test is specifically designed to evaluate binocular vision and eye coordination. During this test, one eye is covered while the patient is asked to focus on a target. The examiner observes the uncovered eye for any movement when the other eye is covered and then again when it is uncovered. If the uncovered eye moves to fixate on the target, this indicates a misalignment, which is crucial for assessing how well the eyes work together.

In contrast, the other tests listed focus on different aspects of visual function. Refraction measures the eye's ability to focus light and determine the correct prescription for lenses, while visual acuity tests assess the sharpness or clarity of vision. Pupil reflex tests evaluate the responsiveness of the pupils to light, providing insight into neurological function but not directly assessing binocular coordination. Thus, the cover test is the appropriate choice for evaluating how well the eyes function together.
