Posterior vitreous detachment is an important step during vitrectomy and can usually be induced by the cutter using suction. Some of the challenging situations are 1. Young patients with adherent posterior hyloid 2. High myopia with frequent vitreoschisis and 3. Vascular proliferations on the posterior hyloid face Some of the techniques that can be used are the use of triamcinolone, soft-tipped cannula with suction acting at the tip, pick or spatula to create a small opening to break the surface tension. In high myopia however the posterior hyloid was irregularly adherent and hence it was not possible to achieve separation and required a forceps to peel the hyloid which is adherent to the retina. In cases with vascular proliferations it was necessary to segment the hyloid face around the proliferations and remove the free hyloid. This provides greater safety.
