To report a case series in which a modified technique was used to remove retained submacular perfluorocarbon liquid (PFCL) secondary to vitreoretinal surgery for rhegmatogenous retinal detachment.
Four patients who had undergone pars plana vitrectomy for rhegmatogenous retinal detachment were further treated with surgical intervention because of retained submacular PFCL. With a three-port pars plana approach, after the internal limiting membrane peeling with indocyanine green staining, a 38-gauge flexible cannula was used to aspirate the submacular perfluorocarbon bubble, followed by fluid-air exchange and air injection into vitreous cavity. Submacular perfluorocarbon liquid was removed successfully and visual acuity had an improvement in all cases.
The surgical removal of retained submacular PFCL using a 38-gauge flexible cannula combined with internal limiting membrane peeling and intravitreal air tamponade may provide anatomical and visual satisfactory outcomes.
报告一组病例，其中采用改良技术清除视网膜脱离玻璃体视网膜手术后残留的黄斑下全氟碳液（PFCL）。
4例因孔源性视网膜脱离接受玻璃体切除术的患者，因黄斑下残留PFCL而接受手术干预。采用三通道扁平部入路，用吲哚菁绿染色剥除内界膜后，使用38G软性套管抽吸黄斑下全氟碳气泡，随后进行液气交换并向玻璃体腔注入空气。成功清除黄斑下全氟碳液，所有病例视力均有改善。
使用38G软性套管联合内界膜剥除及玻璃体腔内空气填塞手术清除残留的黄斑下PFCL，可获得解剖和视觉上令人满意的效果。
