Intraoperative Three-Dimensional Fluorescein Angiography-Guided Pars Plana Vitrectomy for the Treatment of Proliferative Diabetic Retinopathy: The Maximized Utility of the Digital Assisted Vitrectomy.

| Abstract | PURPOSE: To show the usefulness of the intraoperative three-dimensional fluorescein angiography (3D-FA)-guided pars plana vitrectomy. METHODS: The NGENUITY 3D visualization system was used for the digital assisted vitrectomy. Three-dimensional fluorescein angiography-guided pars plana vitrectomy was performed in three patients with vitreous hemorrhage secondary to proliferative diabetic retinopathy. We investigated both whether several angiographic findings can be successfully displayed on the screen during 3D-FA and whether pars plana vitrectomy can be performed simultaneously on the same screen while implementing 3D-FA. RESULTS: In all cases, the abnormal FA findings including hypofluorescence due to non-perfusion areas, and the hyperfluorescence due to macular edema and fibrovascular proliferative membrane were successfully displayed on the screen. The segmentation and delamination of fibrovascular proliferative membrane and panretinal photocoagulation for detected non-perfusion areas were able to be performed on the same screen while implementing 3D-FA. CONCLUSION: Three-dimensional fluorescein angiography-guided pars plana vitrectomy is a novel approach that fully utilizes the advantages of digital assisted vitrectomy and a promising option for the treatment of proliferative diabetic retinopathy.
