What alignment error does the Krimsky Test correct?

The Krimsky Test is designed to assess and correct eye misalignment by focusing on the alignment of the corneal reflexes, which are the reflections of light on the surface of the cornea. By examining how the corneal light reflexes appear in relation to the pupils, this procedure helps to determine the presence and degree of strabismus (misalignment of the eyes).

When performing the Krimsky Test, a prism is placed in front of the deviating eye, which helps to align the corneal reflexes in the same vertical or horizontal position with respect to the pupils. This adjustment allows for both a better understanding of the eye misalignment and an opportunity to quantify it in terms of prism diopters needed for correction.

The other options—such as eye rotation, pupil size variation, and lens clarity—do not specifically pertain to the objective of the Krimsky Test. Eye rotation could inform the practitioner's assessment but is not directly what the test aims to correct, while pupil size variation and lens clarity are factors unrelated to the measurement of alignment in this context. Thus, the primary purpose of the Krimsky Test is indeed related to the alignment of the corneal reflexes.
