Shlomit Schaal, MD; PhD, Maya Bitar, MD; Yoreh Barak, MD; and Lana Rifkin, MD; present the injection of 1000 Centistokes silicone oil using a sutureless 25G vitrectomy technique. A 55-year-old African American gentleman underwent 25G vitrectomy surgery with 1000 centistokes silicone oil injection for the repair of a combined rhegmatogenous and tractional retinal detachment due to proliferative diabetic retinopathy. The video presents air fluid exchange and the injection of the oil through 25G superior temporal cannula. The flattening of the retina during the injection of the oil is demonstrated.

I saw no venting mechanism, with all ports closed. You need to have atleast one port open for the air to come out during injection of the silicone oil. Are you using constellation, what's the infusion pressure for air?? Postop picture would reveal subconjunctival oil, its always wiser to suture.

Thank you so much for your scholarly comments, Dr. Shalabh, I appreciate the discussion. The venting system is the infusion cannula which infuses air under pressure of 18 mmHg. In this specific case we did not use the Constellation machine, but the Accurus. I do use the Constellation, and the procedure is similar. I have never encountered sub-conjunctival oil droplets in this technique, as the sclerotomies are not leaking at the end of the procedure.
