Argyll Robertson Pupil
The Argyll Robertson pupil is usually bilateral and characterised by:
- small, irregular pupils
- the size of the pupils may be unequal
- absence of the light reflex
- a prompt accomodation reflex
- pupils slowly dilate with mydriatics
The most common cause of this condition is syphilis. If the aetiology is syphilitic
then the pupils are generally unequal and irregular. Also there is atrophy and
depigmentation. The ciliospinal reflex is lost. |
