Certified Ophthalmic Technician (COT) Practice Test 2026 - Free COT Practice Questions and Study Guide

The Krimsky test is specifically designed to assess ocular alignment by using prisms to center the corneal reflex in relation to the pupil. This test is particularly valuable in the diagnosis of strabismus (misalignment of the eyes) and allows the examiner to determine the angle of deviation. By measuring the deviation of the corneal reflex with the aid of prisms, the test provides an objective way to quantify the alignment issue, aiding in the decision-making process for treatment or management of strabismus.

The other options focus on different areas of vision assessment. Evaluating refractive errors typically involves techniques like retinoscopy or autorefraction, rather than the centration of the corneal reflex. Assessing color vision usually employs tests like the Ishihara plates or other color vision tests, which do not relate to eye alignment. Checking for depth perception involves tests that detect stereo acuity and 3-dimensional understanding, which is not the purpose of the Krimsky test. Thus, the Krimsky test plays a unique and crucial role in understanding and diagnosing eye alignment issues.
