| 中文摘要 | 黃斑部轉位手術豆計用在尚可能保存中心視力的新生血管型老年性黃斑部退化的患者。手術通常包含三個步驟:第一是玻璃體切除術,以及將液體灌入視網膜與其下色素上皮之間,使得包括視小凹在內的視網膜剝離。第二是經由視網膜切開術或縮短鞏膜而造成視網膜移位。第三是將視網膜移位至新的合適且健康的部位,再使用眼球內矽油填充術,使視網膜復位。臨床上以視小凹到健康的色素上皮及脈絡膜微血管複合體的距離,來決定該採用何種形式的手術方式。經由切除鞏膜而施行的有限型黃斑轉位術(limited macular translocation),可將視小凹最遠移位1500μm.採取360°視網膜切開術的手術方式,可以將視小凹移位3倍視神經盤直徑的距離。最主要的術後併發症為視網膜剝離合併增殖性玻瑙體視網膜病變。另外亦有患者主訴術後併發複視和影像傾斜,黃斑轉位術已被證明是可以改善新生血管性老年性黃斑部退化的一種可行的治療方式。但因追蹤時間尚屬短暫,在技術層面上,對於患者的篩選以及併發症的避免,均有賴眼科醫師投注更多的心力去長期發展。 |
| 英文摘要 | Macular translocation surgery is an emerging surgical technique which is a potentially viable treatment for age-related macular degeneration (AMD). Macular translocation to treat neovascular and exudative AMD involves translocation of the fovea to a site with intact retinal pigment epithelium and choriocapillary. The common surgical steps are (1)compete pars plana vitrectomy with infusion of fluid into the subretinal space to create a retinal detachment involving the fovea, (2)mobilization of the retina through a retinotomy or scleral shortening, and (3)translocation of neurosensory retina to a new RPE site followed by reattachment using intraocular tamponade. Although the number of cases performed worldwide is small at this point, macular translocation has been demonstrated to be successful in restoring vision. The most serious complication was the development of a retinal detachment. The extremely disorienting side effects of diplopia and title image could be prevented or effectively treated by muscle surgery. |
