PURPOSE
To show surgical results of the intraoperative 3D fluorescein angiography-guided pars plana vitrectomy for branch retinal vein occlusion with vitreous hemorrhage and neovascularization elsewhere.
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 branch retinal vein occlusion with vitreous hemorrhage and neovascularization elsewhere.
RESULTS
In all eyes, the scatter retinal photocoagulations for a nonperfusion area, depicted as hypofluorescein, and the segmentation and delamination of the perivascular fibrovascular proliferative membrane, depicted as hyperfluorescein, could be safely performed on the same screen while implementing intraoperative 3D fluorescein angiography.
CONCLUSION
Three-dimensional fluorescein angiography-guided pars plana vitrectomy, a novel approach that fully uses the advantages of digital-assisted vitrectomy, can be one of the useful techniques for the treatment of branch retinal vein occlusion with vitreous hemorrhage and neovascularization elsewhere.
目的
展示术中三维荧光素血管造影引导的节段性玻璃体切除术治疗玻璃体积血伴其他部位新生血管的分支视网膜静脉阻塞的手术结果。
方法
使用 NGENUITY 3D 可视化系统进行数字辅助玻璃体切除术。对 3 例玻璃体积血伴其他部位新生血管的分支视网膜静脉阻塞患者进行三维荧光素血管造影引导的节段性玻璃体切除术。
结果
所有患者均能在术中三维荧光素血管造影的同时，在同一屏幕上安全地对无灌注区（表现为弱荧光）进行散射视网膜光凝，并对血管周围纤维血管性增殖膜进行分段和分层（表现为强荧光）。
结论
三维荧光素血管造影引导的节段性玻璃体切除术充分利用了数字辅助玻璃体切除术的优势，是治疗玻璃体积血伴其他部位新生血管的分支视网膜静脉阻塞的有效方法之一。
