Case 1:

You are doing your newborn nursery rotation and your medical student asks you how babies are screened for hearing.

  • Explain the difference between the Auditory Brainstem Response and the Otoacoustic Emissions tests. What are the advantages/disadvantages of each?
  • Which one does our nursery use for screening? Which is used for screening in the NICU? Which is used if initial screen fails?
  • What are some reasons why a baby would have a false positive hearing screen (fail when hearing is normal)?
  • As a child gets older, how often should he or she be screened?
  • In preschool children, what are some risk factors for hearing impairment?

Case 2:

A 4 yo girl is brought in by mom for her well visit. Mom reports she has noticed her squinting when looking at the TV. She wants to have her vision tested.

  • How often should children have “visual assessments” at well visits?
  • At what age should visual acuity screening begin?

Case 3:

You are seeing an 18 month old girl who is brought in by dad. They just moved to the area and are establishing care. Dad reports she has had a “lazy eye” since birth.

  • How do you evaluate for strabismus on exam?
  • When does strabismus need to be corrected to prevent amblyopia?
  • How is strabismus treated?
