Recurrent choroidal neovascularization after macular translocation surgery with 360-degree peripheral retinectomy.

Abstract

To evaluate the pattern of age-related macular degeneration in the new foveal location after macular translocation surgery with 360 degree peripheral retinectomy for neovascular age-related macular degeneration. Clinical data, fundus photos, and fluorescein angiograms of patients in the Duke Macular Translocation Study were reviewed with 2-year follow-up data. With 56 patients completing follow-up, no patient developed de novo choroidal neovascularization (CNV), geographic atrophy, or drusen in the new subfoveal retinal pigment epithelium bed. By 2 years, 14 patients (25%) developed recurrent CNV and 13 of these 14 recurrences clearly arose from the old CNV bed. Of the 13 recurrences clearly arising from the old bed, 12 of them had recurrent CNV that involved the margin of the bed closest to the repositioned fovea. Smokers were 5.3 times (95% confidence interval: 1.2-24) more likely to develop recurrent CNV over 2 years. Despite treatment, median visual acuity for the 14 eyes with recurrent CNV was 20/200 compared with 20/80 in eyes without recurrence. Findings in this study support the hypotheses that the development of CNV occurs via a signaling mechanism from the fovea.
