Design
This study was a consecutive interventional case series.
Methods
Fifty consecutive eyes of 50 patients who underwent a macular translocation from January 1999 until July 2000 for the treatment of a subfoveal neovascularization due to ARMD are included in this study. Every other etiology was excluded. The mean age was 76 years (range, 56 to 88). All patients had suffered from a recent drop in visual acuity; most of them had been able to read newspaper print until 3 months before the operation.
All patients underwent preoperative and postoperative
Results
Figure 1 shows the preoperative and postoperative BCVA for each eye. In 33 eyes (66%) the BCVA was improved by 2 or more Snellen lines, remained stable in 14 eyes (28%), and decreased by 2 or more lines in 3 eyes (6%). Table 1 shows the preoperative and postoperative visual acuity categories in study eyes: in 32% of the patients the BCVA was 20/50 or better, only 16% had a final BCVA worse than 20/200. An important sign of visual rehabilitation is the ability to read newspaper print: 32% of the
Discussion
The aim of a macular translocation surgery is to move the macula to a healthy area of RPE and choriocapillaris so that the original physiologic environment can be reestablished. This is the reason why this approach is expected to offer a good chance of maintaining or restoring the visual acuity, provided that the macula has not suffered an irreversible damage due to the primary pathology or to the surgical trauma.
Conversely, the intense metabolic activity among macula, RPE, and choriocapillaris

Submacular hemorrhage in neovascular age-related macular degeneration: A synthesis of the literature
2016, Survey of OphthalmologyCitation Excerpt :Nevertheless, it should probably be reserved for patients with a very low initial VA and be performed in centers specializing in this technically complex technique, with ongoing analysis and publication of results. This is because macular translocation is associated with an appreciable rate of significant vitreoretinal complications such as macular pucker, RD, PVR, recurrence of CNV, and choroidal hemorrhage,11,29,107,155 and because alternatives treatment options are now available. Following the results of the Submacular Surgery Trial,12 showing that surgical removal of the CNV complex in SMH has an outcome no better than the natural history, Peyman and colleagues suggested implanting autologous RPE-choroid graft in the subretinal space from whence the CNV lesion was removed.108
