Iridoplegia is the paralysis of the sphincter of the iris. It can occur in due to direct orbital injury, which may result in short lived blurred vision.

Types[edit]

It can be of three types:

  1. accommodative iridoplegia- Noncontraction of pupils during accommodation.
  2. complete iridoplegia- Iris fails to respond to any stimulation.
  3. reflex iridoplegia- The absence of light reflex, with retention of accommodation reflex. Also called Argyll Robertson pupil.
