Argyll Robertson pupil

The Argyll - Robertson sign occurs in cerebral disturbances in the area of the midbrain ( tectum, quadrigeminal plate ).

Clinically, this is shown by a loss of optical reflexes of the eye ( pupillary reflex after exposure to light ), while the motor reflexes ( convergence reaction and near reflex ) are intact - it is therefore a reflex pupillary rigidity ago.

Cause is an injury in aquäduktnahen midbrain, specifically the connection between the nucleus pretectal olivary nucleus to the Edinger - Westphal.

Typically occurs on the Argyll - Robertson sign at the neuro- syphilis ( syphilis ), but also in other diseases (inflammation, tumor). The Scottish eye surgeon Douglas Moray Cooper Lamb Argyll Robertson, after which the character is named, presented in 1869 the link between syphilis and the light rigidity of the pupil fixed.
