What is the purpose of the Krimsky test in ophthalmology?

The Krimsky test is specifically designed to assess strabismus, or eye misalignment, by centering the corneal reflex using prisms. During this test, a prism is placed in front of one of the eyes to align the reflection of a light source on the cornea of both eyes. This technique allows the clinician to evaluate the alignment and coordination of the eyes, particularly in cases of heterotropia, where the eyes do not properly align with each other. By adjusting the strength of the prism until the corneal reflexes are aligned, the test provides valuable information about the degree of strabismus present in the patient, which is crucial for diagnosis and treatment planning. Other options, such as measuring intraocular pressure or assessing visual acuity, do not fall within the purpose of the Krimsky test, as these examine different aspects of ocular health and function.
