Which test is an example of a corneal light reflex test used to detect strabismus?

The Hirschberg test is a recognized corneal light reflex test that is specifically used to detect strabismus, which is an eye condition characterized by misalignment of the eyes. In this test, the examiner shines a light in front of the patient's eyes and observes the reflection of the light on the corneas. In a person with normal eye alignment, the light reflection should be centered on both pupils. However, if there is strabismus, the light reflection will be displaced to one side or the other, indicating which eye is misaligned.

This test is particularly beneficial in identifying the presence of strabismus in both children and adults, allowing for appropriate further assessment and intervention if necessary. The value of the Hirschberg test lies in its simplicity and the quick results it provides, making it a practical option for initial screenings in clinical practice.

Other tests listed, such as the cover test and the Worth 4-dot test, focus on assessing eye alignment and depth perception, but they do not primarily rely on the corneal light reflex for the initial detection of misalignment.
