An unusual case of a high-impact perforating ocular injury by knife

Purpose: To present a case of high-impact perforating eye injury by knife throwing witnessed during a public performance and initially classified as penetrating eye injury.

Observations: During the second reconstructive procedure an exit wound was identified, which had been missed during primary wound repair due to extensive swelling of adjacent soft tissue. The occult exit wound could be sealed and the retina attached under silicone oil.

Conclusions and importance: An exit wound should always be considered in any case of penetrating ocular injury. Uniform terminology in ocular traumatic injuries is important for planning and execution of proper wound management.
