Argyll Robertson Pupil
The Argyll Robertson pupil is usually bilateral and characterized by:
- small, irregular pupils
- the size of the pupils may be unequal
- absence of the light reflex
- a prompt accommodation 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.

Pupil.
