Severe eye trauma in a 65-year-old man resulted in total aniridia, where the iris detached and exited the eye. This case highlights a rare, complete iris avulsion following blunt force injury.

Area of Science:

  • Ophthalmology
  • Traumatic eye injury

Background:

  • Blunt eye trauma can cause various ocular injuries.
  • Aniridia, the absence of the iris, is typically congenital or surgically induced.

Observation:

  • A 65-year-old male experienced severe blunt force trauma to the eyeball.
  • The entire iris was avulsed from the ciliary body.
  • The iris tissue escaped through a small corneal laceration.

Findings:

  • Complete traumatic aniridia was documented.
  • Zonular fibers remained intact post-trauma.
  • Posterior segment of the eye exhibited no traumatic alterations.

Implications:

  • This case presents a rare instance of complete iris avulsion due to blunt trauma.
