The term "Argyll Robertson pupil" refers to a condition whereby the pupils in a person's eyes do not constrict and dilate properly in response to light. This condition is often associated with neurological disorders such as syphilis, which can cause damage to the optic nerve. There are several synonyms for this condition, including "light-near dissociation," "prostitute's pupil," and "holmes-adie syndrome." Other terms used to describe a similar condition include "tonic pupil," "Adie's syndrome," and "postganglionic nerve damage." These terms are all used to describe the same basic condition, whereby the pupils in a person's eyes do not function properly in response to certain stimuli.
