About The Webinar

The pupil is an important indicator of the neurologic health of the central and peripheral nervous system. Through the sympathetic and parasympathetic nerve pathways that innervate the iris, the pupil regulates the amount of light that reaches the retina. The pupil size is in a constant state of flux; a result of labile, dynamic equilibrium between the sympathetic and parasympathetic innervations. Animals with pupils of unequal size (anisocoria) or shape (dyscoria) must be found free of primary or secondary anatomic or mechanical abnormalities before consideration is given to a neurologic dysfunction. Examples of primary or secondary anatomic or mechanical disorders include iris atrophy, uveitis, glaucoma, subluxated lenses and synechia. This presentation will provide you with a step-by-step approach to anisocoria.
