Fig. 3From: Microincision vitrectomy surgery: experimental visualization and quantification of vitreous contaminationThese procedures were carefully monitored using an intraocular fiber catheter (a, b). With the injection of saline solution, the microsphere particles were injected through the infusion cannula (arrowhead) and then spread into the vitreous cavity (arrow). We visually detected fluorescent microspheres in 10/10 eyes injected through a 25-G-, and 10/10 with a 27-G, cannulaBack to article page
