MRCP revision battle 22.7: Argyll Robertson Pupil

I love the Argyll Robertson pupil, and have done ever since a very serious elderly consultant intoned to us that "the Argyll Robertson pupil is like a prostitute... it will accommodate but will not react."

Essentially the Argyll Roberston pupil is a pupil that:
  • will not react to light
  • will accommodate

It is a sign of neurosyphillis, but a similar phenomenon occurs in diabetes.
They are also seen in Parinaud's syndrome, which will be covered tomorrow.

And on that teaser, adieu!
