Which test is NOT typically used to assess strabismus?

The refraction test is primarily used to determine a person's prescription for glasses or contact lenses. It assesses how well the eye focuses light and helps identify refractive errors such as myopia, hyperopia, and astigmatism. While it is an important part of a comprehensive eye examination, it does not specifically evaluate the alignment or coordination of the eyes, which is crucial in the diagnosis and management of strabismus.

In contrast, the cover-uncover test, convergence testing, and cover test are all diagnostic procedures directly aimed at assessing eye alignment. The cover-uncover test checks how well the eyes work together by alternately covering one eye and observing how the uncovered eye moves to fixate. Convergence testing evaluates the ability of the eyes to work together as they focus on a near target. The cover test, similar to the cover-uncover test, assesses the presence and magnitude of strabismus by observing eye movement when one eye is covered and then uncovered.

These latter tests are focused on detecting misalignments and measuring the effectiveness of both eyes working together, making them appropriate for assessing strabismus.
