Retina/Vitreous, Vitreoretinal Surgery
In this video, Drs. Sami Uwaydat and Riley Sanders show how a misdirected infusion cannula caused air to fill the anterior chamber of a patient undergoing a routine 23-gauge pars plana vitrectomy for the repair of a phakic rhegmatogenous retinal detachment. During air-fluid exchange, the view of the fundus suddenly became hazy. Inspection of the anterior segment showed a large air bubble in the anterior chamber, with the infusion cannula tilted anteriorly. The direction of the infusion cannula was readjusted, and the air bubble was removed through an anterior chamber paracentesis. The lens remained clear, with no evidence of zonular dehiscence. The vitrectomy was completed without further complications. During vitrectomy, care should be taken to monitor the position and orientation of the infusion cannula, especially following manipulation of the eye with a depressor while searching for peripheral breaks.
