Clinical Minute Retina

Vitreous Sensing Vitrectomy

Maria Berrocal, MD and Jordan Deaner, MD

Show Description +

Can inflow rate be used to detect whether a vitrectomy probe is actively removing vitreous? In this episode of Clinical Minute: Retina, host Maria Berrocal, MD, speaks with Jordan Deaner, MD, about a novel technique for sensing vitreous during surgery. Dr. Deaner describes a study using porcine eyes to evaluate inflow rate as a proxy for vitreous removal across all vitrectomy gauges, cut rates, and vacuum settings, and discusses how the viscosity difference between vitreous and BSS produces a measurable, consistent signal. They explore the clinical implications of this approach, review potential audible and visual intraoperative cues, and discuss why higher cut rates may improve the efficiency of vitreous removal.
