Summary

To evaluate the effect of partial posterior hyaloidectomy on preventing iatrogenic retinal breaks related to induction of a posterior vitreous detachment

Conditions

  • Retinal Break
  • Retinal Detachment

Interventions

PROCEDURE

Partial posterior hyaloidectomy (a modified procedure of vitrectomy)

The core vitrectomy entails more extensive removal of vitreous gel, in contrast to the conventional core vitrectomy. IPVD was conducted by engaging the attached posterior cortical vitreous with a 23-gauge needle with angulated tip in the area adjacent to the optic disc followed by gently moving the tip to approximately 3 disc diameters away from the margin of the optic disc. After then, slightly elevating the tip in a posteroanterior direction with slowly proceeding it to the extent that we planned. With IPVD, the surgeon was able to visualize a floating Weiss ring in all of the cases. Active suction to initiate IPVD was not used in any of the cases. In the temporal direction, the extension of a PVD was restricted to approximately 2 disc diameters distance beyond the margin of temporal major vascular arcade
