Anisocoria: A Problem in the Pathway

14 May 2020
Clinical Theater 2

Anisocoria, or uneven pupil size, can be easy to diagnose in many cases. Then comes the more difficult tasks of deciding which of the two pupils is abnormally sized and why. This session will include a review of the structures and pathways involved in governing pupil size and light response. It will also include a discussion of common disorders that result in anisocoria such as Horner’s syndrome, ophthalmoplegia, and spastic pupil syndrome.

  • - Recognize anisocoria and determine which pupil is abnormal.
  • - List the structures involved in determining pupil size and light response.
  • - Develop a differential list for unilateral mydriasis and miosis.
  • - Formulate a diagnostic plan for a patient with anisocoria.
