NBEO Part III Patient Encounters and Performance Skills (PEPS) Practice Test

This approach is used to evaluate allergic keratoconjunctivitis with lid involvement, especially VKC and AKC. Fluorescein staining highlights epithelial defects and corneal surface changes, while eversion of the upper lid exposes the palpebral conjunctiva and tarsal papillae that are hallmark features of these conditions. In VKC and AKC, you often see pronounced lid irritation with giant papillae on the tarsal conjunctiva and possible corneal involvement like shield ulcers or other epithelial disruptions that fluorescein can reveal. So this combination specifically targets the kinds of lid/conjunctival and corneal findings seen in vernal and atopic keratoconjunctivitis.

Other scenarios don’t fit as precisely. Allergic conjunctivitis alone is broader and may not emphasize the distinct lid-margin findings; bacterial conjunctivitis centers on discharge and different staining patterns rather than the characteristic lid conj changes seen with VKC/AKC; glaucoma is unrelated to corneal epithelial staining or lid conj findings and is evaluated through intraocular pressure and optic nerve assessment rather than this staining technique.
