[Translocation of the macula for retrofoveal choroidal neovascularization in age-related macular degeneration and severe myopia: first results].

BACKGROUND: Subfoveal choroidal neovascularization is a main cause of blindness. The new surgical technique of macular translocation conceived by De Juan, with scleral shortening and without a retinotomy, allows to move the fovea away from the neovascular membrane with a low rate of complications. The first results obtained with this technique are presented here, in cases of submacular neovascularization due to age-related macular degeneration (AMD) or degenerative myopia.

PATIENTS AND METHODS: The first 10 patients who were operated on with this technique presented with subfoveal neovascularization due to AMD (6 eyes) or myopia (4 eyes). The time period between the beginning of the disease and surgery was less than 3 months. Before and after surgery, a complete examination included fluorescein and ICG angiographies and OCT.

RESULTS: Visual acuity improved by 2 lines or more in 6 eyes (60%), was unchanged in 3 eyes (30%) and decreased in 1 eye. The improvement in vision seemed higher in myopia than in ARMD. Conversely, the mean foveal displacement was greater in ARMD than in myopia (1.2 disc diameter and 0.5 respectively). Laser photocoagulation has been performed in all patients after surgery. Main complications were retinal detachment (1 eye) and neovascularization at the site of transretinal injection (1 eye). Mean follow-up was 3 months.

COMMENTS: Macular translocation with the technique described by De Juan allowed visual improvement in more than the half of the eyes with subfoveal neovascularization, resulting in a moderate rate of complications. Long term follow-up is necessary to confirm these results.
