Ophthalmology · Ocular trauma: retinal dialysis

Sample item

After blunt injury, which is the commonest site of a traumatic retinal dialysis?

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

The answer and the reasoning

B. Inferotemporal quadrant

Traumatic dialysis at the ora serrata most often occurs in the inferotemporal quadrant, and the superonasal quadrant is next. Detachment can occur months later because of slow progression. Examination of the periphery is needed after blunt trauma.

Option by option

  • A. Superonasal quadrant

    The superonasal quadrant is the second commonest site.

  • B. Inferotemporal quadrant (correct)

    Correct. The inferotemporal retina is most often torn at the ora.

  • C. Optic disc margin

    The disc margin is not a site of dialysis.

  • D. Macula

    The macula is injured by commotio or hole, not by dialysis.
