Ophthalmology · Retina: tractional detachment

Sample item

A patient with proliferative diabetic retinopathy has a taut fibrovascular membrane pulling the retina forward. What is the best treatment?

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

The answer and the reasoning

D. Pars plana vitrectomy

Tractional detachment results from contracting fibrovascular tissue, and the traction must be removed by vitrectomy with membrane peeling. Pneumatic retinopexy treats simple retinal breaks.

Option by option

  • A. Cryotherapy

    Cryotherapy does not release membranes.

  • B. Photocoagulation alone

    Laser alone cannot relieve traction.

  • C. Pneumatic retinopexy

    Pneumatic retinopexy is for superior retinal breaks without traction.

  • D. Pars plana vitrectomy (correct)

    Correct. Vitrectomy relieves the traction.
