Which test uses prism to center the corneal reflex?

  1. Hess

  2. Worth four dot

  3. Hirschberg

  4. Krimsky

The correct answer is: Krimsky

The test that uses a prism to center the corneal reflex is the Krimsky test. This test is used to measure and correct any ocular deviation or misalignment. By placing a prism over one eye, the corneal light reflex is displaced to the deviated eye. The prism is then adjusted until the corneal reflex is centered, indicating the amount of deviation present. The other options - Hess, Worth four dot, and Hirschberg - are tests used for different purposes in assessing ocular alignment and binocular vision.
