Special Techniques for Pars Plana Vitrectomy

  • Ulrich Spandau

Lens = front or anterior, retina = back or posterior. A peripheral break is equivalent to an anterior break, and a central break is equivalent to a posterior break (Fig. 4.1). 12 o’clock is up, 6 o’clock is below. You make a sclerotomy not below the limbus but behind or posterior to the limbus. You move the vitreous cutter from the back (retina) to the front (lens).
