Hirschberg Test
The Hirschberg test is used to assess eye alignment by comparing the position of the corneal light reflexes of each eye when the patient looks at a light source held by the examiner.
Survival Tips!
-
The corneal light reflex is the highlight seen on the cornea when a light is shined directly at the eye.
​
-
Evaluations of eye alignment are a critical survival skill, as abnormalities can be a sign of serious, and occasionally life-threatening pathology.
​
-
The Hirschberg test is the easiest, but least specific way, to assess eye alignment.​
​
-
The alternate cover test is a more specific alternative.​​
​
-
This test is typically used with children.
​
-
The magnitude of strabismus is measured in prism diopters.​
​
Remember:​
​
-
This test is only accurate if the patient is looking directly at the light source.
Emergency Care To Note
-
Remember, the key to survival is to recognizing red flags, and taking the appropriate steps to evaluate them without undue delay. Acute onset strabismus is a red flag.
