Improving the volume of vitreous extracted is an important target to increase the diagnostic yield.

Abstract
Improving the volume of vitreous extracted is an important target to increase the diagnostic yield. To achieve this goal in our hospital (Ophthalmic Depart- ment, Academic Medical Center, Amsterdam, the Netherlands), we usually perform a 25-G PPV using air as the sole perfusion following a standard three- port technique. Before starting the procedure, the infusion line is flushed with air to ensure no contam- ination from fluid. Then, the trocars are inserted through the sclera and the position of the infusion line in the vitreous is confirmed. The vitrectomy handpiece is directly connected to a 10-mL syringe. Meanwhile, the surgeon controls the cut rate and positions the handpiece as needed, the assistant manually aspirates the vitreous into the syringe. A core or complete PPV can be performed in this way, using only air infusion to maintain the intraocular pressureI documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
