To report a surgical method for translocation of the foveal retina in eyes with subfoveal choroidal neovascularization.
In three eyes of three patients, a crescent-shaped, partial-thickness scleral resection was performed near the equator at either the superotemporal or the inferotemporal quadrant. A near-total retinal detachment was created; then the edges of the resected sclera were sutured, causing shortening of the sclera with subsequent reattachment of the retina, resulting in translocation of the fovea to an area overlying nonfoveal retinal pigment epithelium and choroid.
In three eyes of three patients, the fovea was surgically translocated to overlie retinal pigment epithelium that preoperatively was not underlying the fovea. In two patients, laser photocoagulation was applied to the choroidal neovascularization that, after translocation of the fovea, was no longer subfoveal, so that the photocoagulation was not associated with immediate visual loss. After a follow-up of 4 to 6 months, the visual acuity had improved in all patients (from 20/126 preoperatively to 20/70 in one patient, from 20/200 preoperatively to 20/70 in the second, and from 20/160 to 20/30 in the third). The patients noted distortion or tilting of the images, which improved over time.
Limited foveal translocation may offer a therapeutic modality to preserve or improve vision in cases of subfoveal choroidal neovascularization. Additional follow-up is needed to assess the impact of potential complications associated with the surgical procedure, such as retinal detachment, proliferative vitreoretinopathy, and cataract, as well as the possibility of recurrent choroidal neovascularization.
报告一种针对黄斑下脉络膜新生血管化眼的黄斑视网膜移位手术方法。
在3例患者的3只眼中,于颞上象限或颞下象限赤道附近进行新月形、部分厚度的巩膜切除术。造成近乎完全的视网膜脱离;然后缝合切除巩膜的边缘,导致巩膜缩短,随后视网膜重新附着,从而使黄斑移位至覆盖非黄斑视网膜色素上皮和脉络膜的区域。
在3例患者的3只眼中,黄斑通过手术移位至术前未位于黄斑下方的视网膜色素上皮之上。2例患者对脉络膜新生血管进行了激光光凝,在黄斑移位后,脉络膜新生血管不再位于黄斑下,因此光凝未导致立即视力丧失。经过4至6个月的随访,所有患者的视力均有所提高(1例患者从术前的20/126提高到20/70,第2例从术前的20/200提高到20/70,第3例从20/160提高到20/30)。患者注意到图像有变形或倾斜,随着时间推移有所改善。
有限的黄斑移位可能为黄斑下脉络膜新生血管化病例提供一种保留或改善视力的治疗方式。需要进一步随访以评估与手术相关的潜在并发症的影响,如视网膜脱离、增殖性玻璃体视网膜病变和白内障,以及脉络膜新生血管复发的可能性。
