Three cases of age-related maculopathy with severe and recent massive submacular hemorrhage were treated by performing complete vitrectomy. A total retinal detachment was created by infusion of fluid underneath the retina, followed by a peripheral circumferential retinotomy. This allowed access to the subretinal space for removal of blood and membranes and, more importantly, permitted rotation of the retina with relocation of the fovea. Rotations between 30 degrees and 80 degrees were achieved. One patient with 5 months' follow-up had a visual improvement from 1/200 to 20/80 and excyclorotation of images. The other two patients developed proliferative vitreoretinopathy after initially successful rotation. Their retinas were reattached after surgical removal of the membranes and silicone oil tamponade, but visual function remained low. The rationale for this treatment is that relocating the fovea to an area where pigment epithelium is less diseased than in the central area may allow for recovery of some useful vision.
对3例患有严重且近期出现大量黄斑下出血的年龄相关性黄斑病变患者实施了完全玻璃体切除术。通过在视网膜下方注入液体造成完全性视网膜脱离,随后进行周边环形视网膜切开术。这使得能够进入视网膜下间隙以清除血液和膜,更重要的是,允许视网膜旋转并使黄斑中心凹重新定位。实现了30度至80度的旋转。1例随访5个月的患者视力从1/200提高到20/80,图像出现外旋转。另外2例患者在最初成功旋转后发生了增殖性玻璃体视网膜病变。在手术切除膜并进行硅油填塞后,他们的视网膜重新附着,但视觉功能仍然低下。这种治疗方法的基本原理是将黄斑中心凹重新定位到色素上皮病变程度低于中心区域的区域,可能会使一些有用视力得以恢复。
