Long-term results after limited macular translocation surgery for wet age-related macular degeneration.

ABSTRACT: To evaluate the long-term results of limited macular translocation (LMT) surgery with radial chorioscleral outfolding in patients with wet age-related macular degeneration (AMD) and subfoveal choroidal neovascularization (CNV). In addition, to identify the factors associated with the final best-corrected visual acuity (BCVA).The medical records of 20 eyes of 20 consecutive patients (65.2±9.8 years) who had undergone LMT for the treatment of wet AMD and were followed for at least 5 years, were reviewed. The surgical outcomes including the BCVA, degree of foveal displacement, and complications were recorded.The mean foveal displacement was 1332 ± 393 ?m after the LMT. The CNV was removed in 16 eyes and photocoagulated in 4 eyes. The mean preoperative VA was 0.83 ± 0.33 logMAR units which significantly improved to 0.59 ± 0.37 logMAR units at 1 year after the surgery (P = 0.015). This BCVA was maintained at 0.59 ± 0.41 logMAR units on the final examination. The final BCVA was significantly correlated with that at 1 year after the surgery (r = 0.83, P<0.001). Multiple linear regression analysis showed that the final BCVA was significantly correlated with the BCVA at 1 year after the surgery (P<0.001), a recurrence of a CNV (P = 0.001), and the age (P = 0.022).LMT improves the BCVA significantly at 1 year, and the improved BCVA lasted for at least 5 years. These results indicate that the impaired function of the sensory retina at the fovea can recover on the new RPE after the displacement for at least 5 years. The ability to maintain good retinal function on the new RPE for a long period is important for future treatments of CNVs such as the transplantation of RPE cells and stem cells.

Project description:PURPOSE:To assess whether publication of Comparison of Age-related macular degeneration Treatment Trial (CATT) results and introduction of aflibercept to the marketplace affected intravitreal bevacizumab and ranibizumab utilization. DESIGN:Retrospective analysis of treatment patterns. METHODS:We calculated weekly bevacizumab and ranibizumab utilization during 3 timeframes: (1) before CATT publication, (2) between CATT publication (April 28, 2011) and assignment of a unique aflibercept billing code (January 1, 2013), and (3) afterward for 164,188 Medicare beneficiaries with neovascular macular degeneration receiving ?1 anti-vascular endothelial growth factor injection(s) from January 1, 2008 to December 31, 2014. We identified ophthalmologists who predominantly (?80%) administered bevacizumab or ranibizumab and evaluated changes in preferences over the 3 periods. We replicated analyses on 881,381 commercially insured beneficiaries. RESULTS:Among 317 ophthalmologists administering predominantly ranibizumab to Medicare beneficiaries pre-CATT, 221 (69.7%) reduced ranibizumab use post-CATT, whereas 96 (30.3%) continued using ranibizumab ?80% of the time. Findings were reversed among 1041 ophthalmologists who predominantly administered bevacizumab pre-CATT-777 (74.6%) continued bevacizumab-predominant use while 264 (25.4%) reduced bevacizumab use post-CATT. Among the 145 ophthalmologists who predominantly administered ranibizumab before aflibercept's availability, 77 (53.1%) reduced ranibizumab utilization and 68 (46.9%) continued using ranibizumab ?80% of the time after aflibercept became available. Corresponding numbers among the 909 ophthalmologists who predominantly administered bevacizumab pre-aflibercept were 381 (41.9%) reducing and 528 (58.1%) continuing bevacizumab-predominant use. Similar results were observed for commercially insured patients. CONCLUSIONS:Many ophthalmologists who favored ranibizumab switched to bevacizumab after CATT publication, while most who favored bevacizumab before CATT publication continued favoring it afterward. Aflibercept's introduction had little impact on preferences for ranibizumab or bevacizumab.
