<unk> s (“AR pupils”) are bilateral small pupils that constrict when the patient focuses on a near object (they “accommodate” with near vision), but do not constrict when exposed to bright light (they do not “react” to light).  They were formerly known as "prostitute's pupils" because of their association with syphilis and because, like a prostitute, they “accommodate but do not react.”).   They are a highly specific sign of neurosyphilis. Pupils that “accommodate but do not react” are said to show light-near dissociation.  A video of AR pupils and light-near dissociation is available at http://content.lib.utah.edu/u?/EHSL-Moran-Neuro-opth,60
AR pupils are extremely uncommon in the developed world.  There is continued interest in the underlying pathophysiology, but the scarcity of cases makes ongoing research difficult.
