Argyll Robertson pupils (AR pupils) are bilateral small pupils that reduce in size on a near object (i.e., they accommodate), but do not constrict when. It is commonly called prostitutes pupil due to the relation to neurosyphilis and because it accommodates but does not react. The meaning of ARGYLL ROBERTSON PUPIL is a pupil characteristic of neurosyphilis that fails to react to light but still reacts in accommodation to distance. It is a constricted pupil that accommodates when focusing on a near object but does not react to light. The rostral midbrain in the vicinity of the cerebral aqueduct of the third ventricle is the most likely region of damage.Ī lesion in this area would involve efferent pupillary fibers on the dorsal aspect of the Edinger-Westphal nucleus. An Argyll-Robertson pupil is a specific finding in neurosyphilis. The Argyll Robertson pupil, a miotic pupil that responds to an accommodation effort but fails to react to direct light, has been described in medical literature. The mechanism which produces an Argyll Robertson pupil is believed to be the result of bilateral damage to the pretectal nuclei in the midbrain, without a focal localising lesion. It is extremely uncommon in the developed world. Pupils that accommodate but do not react are said to show light-near dissociation. Technically, to have an Argyll Robertson pupil, the involved eye must have some vision, to ensure the light-near dissociation is not due to a deafferented pupil.
