Argyll-Robertson pupil

Argyll-Robertson pupil

An ocular finding, now of largely historic interest, for a pupil that can focus on a near object (accommodate) but does not react to light, which is classically described in tertiary syphilis. Near-light dissociation is also seen with Adie tonic pupil syndrome, a benign peripheral neuropathy which, in contrast to the brisk and immediate response of AR pupils, is characterised by a slow and prolonged near response.
