摘要
Purpose: Different techniques have been proposed for translocating the macula in patients with subfoveal neovascularization secondary to age-related macular degeneration. A new approach utilizing radial outfolding of the sclera was investigated. Materials and methods: Surgical techniques and retinal displacement were evaluated in animal trials using metal scleral clips. Successful translocation and reattachment of the retina was achieved in eight rabbits (eight eyes). We conducted a retrospective review of macular translocation surgery, performed with radial scleral outfolding, in a series of five consecutive human patients (five eyes) using full-thickness transscleral mattress sutures. Results: After surgery, vision improved in two of five patients, with one patient achieving a visual acuity of 20/50. The mean an-le of rotation was 11.5 deg (range 8.6-15.1). The mean amount of foveal displacement was 1276 mum (range 852-1620). Complications included one case of retinal detachment, one of diplopia, and one of subretinal hemorrhage. Conclusions: Limited macular translocation by radial scleral outfolding can improve vision in selected patients. Radial evagination appears to be as effective as circumferential infolding.
