Ophthalmology · Community: ocular trauma classification

Sample item

In the Birmingham Eye Trauma Terminology system, which term is used for a full-thickness wound of the eye wall made by a sharp object, with entry only?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Penetrating injury

BETT classifies injuries as closed globe (contusion or lamellar laceration) or open globe (rupture by blunt force, or laceration). Open globe lacerations are subdivided into penetrating (single entry wound), perforating (entry and exit) and intraocular foreign body. The term rupture applies to blunt trauma.

Option by option

  • A. Lamellar laceration

    Lamellar laceration is a partial thickness wound in the closed globe category.

  • B. Rupture

    Rupture results from blunt trauma, and the wound is inside-out.

  • C. Penetrating injury (correct)

    Correct. A single entry wound is penetrating.

  • D. Perforating injury

    Perforating means both entry and exit wounds.
