Certified Ophthalmic Assistant Practice Exam

Which eye care professionals specialize in measurements of eye movement and the extraocular muscles?

1. Opticians

2. Orthodontists

3. Optometrists

4. Orthoptists

The correct answer is: Orthoptists

Orthoptists specialize in the measurement of eye movement and the evaluation of the extraocular muscles. They typically work alongside ophthalmologists to diagnose and treat eye movement disorders such as strabismus (eye misalignment) and amblyopia (lazy eye). Opticians, on the other hand, are trained to design, verify, and fit eyeglass lenses and frames, while optometrists focus on primary eye care services such as vision testing and prescribing corrective lenses and detecting common eye abnormalities. Orthodontists, on the other hand, are dental specialists who focus on the alignment of teeth and jaws rather than eye care.
