Inflammatory responses after vitrectomy with vitreous substitutes in a rabbit model

To investigate the inflammatory response of current and future potential vitreous substitutes in an experimental in vivo vitrectomy model. Twenty-five gauge pars plana vitrectomy was performed in the right eye of 60 pigmented rabbits, with subsequent injection of 0.5–1.0 ml of Healaflow® (cross-linked hyaluronic acid, n = 12), Bio-Alcamid® (polyalkylimide, n = 8), silicone oil (n = 12), or balanced saline solution (BSS, n = 28).
