Perfluorocarbon in vitreoretinal surgery and preoperative bevacizumab in diabetic tractional retinal detachment

Figure 1 Artist's representation of surgical technique. A: An opening is made with the vitrector in the mid-periphery of the posterior hyaloid; B and C: Perfluorocarbon liquid (PFCL) is injected to separate the posterior hyaloid from the retina. A dual bore cannula (for 23-gauge cases) attached to a 5 cc syringe filled with PFCL is used to separate membranes and posterior hyaloid from the underlying retina; D: Once all the tissues have been separated from the retina, vitrectomy can be continued up to the periphery; E: Endolaser is applied under PFCL; F: An air-fluid and an air-gas (C3F8) exchange exchange are performed to end the case.

Figure 2 En bloc perfluorodissection performed in a case of tractional retinal detachment in proliferative diabetic retinopathy. A: An opening is made with the vitrector in the mid-periphery of the posterior hyaloid; B: Perfluorocarbon liquid (PFCL) is injected to separate the posterior hyaloid from the retina (arrows). A dual bore cannula (for 23-gauge cases) attached to a 5 cc syringe filled with PFCL is used to separate membranes and posterior hyaloid from the underlying retina; C: Once all the tissues have been separated from the retina, vitrectomy can be continued up to the periphery; D: Endolaser is applied under PFCL (shown). An air-fluid and an air-gas (C3F8) exchange are performed to end the case (not shown).
