Hirschberg test
Hirschberg test
The Hirschberg test, also known as the Hirschberg corneal reflex test, is a simple, non-invasive medical examination used to assess the presence and degree of strabismus, or misalignment of the eyes.
Pronunciation
Hirschberg test: /ˈhɪrʃbɜːrg tɛst/
Etymology
The test is named after the German ophthalmologist Julius Hirschberg who first described it in the late 19th century.
Description
The Hirschberg test involves shining a light into the patient's eyes and observing the reflection off the cornea. In a normally aligned eye, the light will reflect back from the center of the cornea. If the eyes are misaligned, the light will reflect back from a different point on the cornea. The degree of misalignment can be estimated based on the location of the reflection.
