According to Wikipedia, the eye finding (Argyll-Robertson pupils) is also known as prostitute’s pupils because, “like a prostitute, they accommodate but do not react.” This is neurosyphilis, also known as tabes dorsalis. It is a disease of the posterior columns of the spinal cord and of the dorsal roots. It has a long latency between primary infection and onset of symptoms.
