Which test uses prisms to align the corneal reflex?

The test that utilizes prisms to align the corneal reflex is the Krimsky test. This examination is particularly effective in assessing strabismus, or misalignment of the eyes. During the Krimsky test, prisms are placed in front of one eye to compensate for the misalignment, allowing the observer to align the light reflexes in the corneas of both eyes. The goal is to bring them into alignment by adjusting the amount of prism used, which helps to quantify the degree of deviation in strabismus.

In contrast, the other tests mentioned have different methodologies. The Hess test is used to evaluate the eye muscle function by measuring the motility of each eye through a series of fixations on targets while using a light source. The Worth four dot test is used to assess binocular vision and depth perception rather than specifically aligning the corneal reflexes. The Hirschberg test, on the other hand, allows for a qualitative assessment of strabismus by observing the corneal light reflex but does not use prisms to realign these reflexes as the Krimsky test does.
