tympanic membrane of an infant

  1. my book says that an infant's tympanic membrane may look "injected" - what does that mean?

    The normal tympanic membrane should appear pearly gray, and you should not be able to see blood vessels except on the outer margins. When you can see blood vessels (other than on the margins), this is referred to as "injected."
