Which pupil response is associated with Argyll Robertson pupil?

The Argyll Robertson pupil is classically characterized by a specific response pattern to light and accommodation. In this condition, the pupil does not constrict in response to light (indicating a light reaction deficiency) but does respond appropriately to accommodation, meaning it constricts when focusing on nearby objects. This specific dysfunction is often associated with neurosyphilis.

By understanding the characteristics of the Argyll Robertson pupil, it becomes clear why the response pattern described—where the pupil accommodates but does not react to light—accurately describes this condition. This phenomenon is in contrast to other pupil abnormalities. The light reaction impairment is significant, as it distinguishes Argyll Robertson pupils from other types of pupillary responses.
