| ICD-10 online (WHO version 2019) | |
The Argyll-Robertson sign occurs in cerebral disorders in the area of the midbrain (tectum, four-hill plate).
Clinically, this is shown by a loss of the optical reflexes of the eye ( pupillary reflex after exposure to light), on the other hand the motor reflexes (convergence reaction and close-up reaction) are intact - so there is a reflex pupillary rigidity .
The cause is damage to the midbrain near the aqueduct , more precisely the connection between the nucleus praetectalis olivaris and the nucleus Edinger-Westphal .
The Argyll-Robertson sign typically occurs in neurosyphilis ( syphilis ), but also in other diseases (inflammation, tumor). The Scottish eye surgeon Douglas Moray Cooper Lamb Argyll Robertson , after whom the sign is named, established the link between syphilis and light rigidity of the pupils in 1869.
