Certified Ophthalmic Assistant Practice Exam

How is extraocular movement typically assessed in a clinical setting?

1. Confrontation visual fields

2. Visual acuity test

3. Swinging flashlight test

4. Hirschberg test

The correct answer is: Hirschberg test

Extraocular movement is typically assessed in a clinical setting using the Hirschberg test. The Hirschberg test evaluates the alignment of the eyes by observing the reflection of light on the patient's corneas. By assessing how the light reflects in relation to the center of the pupil, eye deviations such as strabismus can be identified. This test provides valuable information about the coordination of the extraocular muscles and helps in diagnosing eye alignment disorders. Confrontation visual fields, visual acuity tests, and the swinging flashlight test are also essential components of an ophthalmic exam, but they do not directly assess extraocular movement, making them incorrect choices for this question.
