Visualization of residual perfluorocarbon liquid using intravitreal triamcinolone acetonide

The visualization of transparent perfluorocarbon liquid (PFCL) using triamcinolone acetonide is described. Intravitreal injection of triamcinolone acetonide enabled visualization of residual PFCL intraoperatively. In addition, it was shown that triamcinolone acetonide could visualize PFCL in an in vitro preparation of balanced salt solution. This in vitro experiment confirmed that triamcinolone acetonide also could be adsorbed by PFCL outside the vitreous. Triamcinolone acetonide was helpful to visualize transparent PFCL both in vivo and in vitro, and may be useful at the end of vitrectomy to completely remove residual PFCL from the eye.
