pupillary cyst

pupillary dilatation

pupillary light reflex

constriction of a dilated pupil in response to an increase in light intensity and a dilatation of a constricted pupil in response to a decrease in the intensity. Activity of the reflex indicates the efficiency of the retina, the optic and oculomotor nerves and the musculature of the iris.

pupillary membranectomy

a surgical technique for resection of an iridocapsular membrane, formed as a sequela to cataract surgery.

persistent pupillary membrane

nonvascular remnants of the tunica vasculosa lentis may extend across the iris or from the iris to the cornea, often producing a corneal opacity at the site. A common defect in dogs, particularly in Basenjis.

pupillary zone
