title: [Progression of choroidal neovascularization after macular translocation in age-related macular degeneration and degenerative myopia].
abstract: OBJECTIVE
  To study the progression of choroidal neovascularization (CNV) after macular translocation in age-related macular degeneration (AMD) and degenerative myopia.
  
  
  METHODS
  The data from 42 consecutive eyes (28 AMD, and 14 degenerative myopia) operated on by limited macular translocation (DeJuan technique), with a follow-up of 6 months or more, were prospectively analyzed. In the AMD group, neovascularization was classic in 54% of eyes and classic and occult in 46% of eyes. Previous laser treatment was applied on extra- or juxtafoveal CNV in 3 eyes. The major outcome measures were visual acuity, fluorescein and indocyanine green angiographies.
  
  
  RESULTS
  After translocation, foveal displacement was greater in AMD than in myopic eyes (mean: 1 260 and 812 micro m, respectively). Laser photocoagulation was applied postoperatively onto extra-or juxtafoveal CNV in 26 (93%) AMD eyes and 12 myopic eyes (86%). Mean follow-up was 10 months (range, 6-18 months). Recurrence of CNV occurred in 14 AMD eyes (50%) and 2 myopic eyes (14%) an average of 5.6 months after surgery (range, 1-18 months). Recurrence was more frequent in AMD eyes with preoperative occult CNV (66%) than without (36%). Recurrence reached the new fovea in 69% of cases. Supplementary laser treatment was possible and successful on extra- or juxtafoveal recurrence in 3 eyes. Recurrence was significantly correlated with a poor visual prognosis: eyes without recurrence or with extra- or juxtafoveal recurrence had a final gain in visual acuity of 2.4 lines, eyes with subfoveal recurrence had a loss of 1.3 lines, and eyes with diffuse recurrence had a loss of 4.2 lines. CNV appeared in a new area at a BSS injection site in one eye. Occult CNV seemed to fade relatively within the first postoperative weeks, but were unchanged at the end of follow-up. In one eye, a small polypoidal lesion near the disc noted preoperatively disappeared after surgery.
  
  
  CONCLUSIONS
  Our results suggest that the surgical procedure does not affect the course of classic or occult CNV. The rate of recurrence of CNV after macular translocation seemed similar to that observed after conventional laser treatment for extrafoveal CNV in AMD. Neovascular recurrence is the most frequent postoperative complication and was frequently directed at the new fovea. Despite these complications, macular translocation moves CNV outside of the subfoveolar zone so the eyes can be treated with conventional laser, leading to a favorable outcome at the last follow-up in 57% of cases. Further studies are required to confirm these findings and to define the best criteria for treatment.
