A method for induction of posterior vitreous detachment during vitrectomy.

Complete surgical removal of the posterior vitreous requires the presence of a posterior vitreous separation from the retina. Although a partial or complete posterior vitreous detachment is usually present before surgery, occasionally this separation must be induced during the course of a pars plana vitrectomy. A simple method for creation of a posterior vitreous detachment during surgery is described. This alternative technique seems to be an efficient and safe method for achieving this important surgical objective.
