Full macular translocation following photodynamic therapy in neovascular age-related macular degeneration

Abstract

Purpose: To report the long-term functional and anatomical outcome of full macular translocation (FMT) in eyes with neovascular age-related macular degeneration (AMD) following photodynamic therapy (PDT). Methods: Twelve eyes of 12 consecutive patients with neovascular AMD who were PDT-nonresponders and underwent FMT were analysed. Best-corrected visual acuity (BCVA) measurement, fundus photography, and fluorescein angiography at baseline and at follow-up examinations in 3 months intervals were performed. Primary end point was change of BCVA from baseline to last visit. Results: Totally 12 eyes of 12 patients were analysed. Mean time interval between the last PDT and FMT was 3.7 months (range 1-10 months). Mean follow-up after FMT was 25.6 months. BCVA ranged at baseline from 20/1000 to 20/80 (mean 20/230). At the last visit, mean BCVA was by 20/185. BCVA improved in 50% (6/12) of eyes by more than 1 line. Twenty five per cent (3/12) of eyes had final BCVA within ±1 line from baseline. In 25% (3/12) of eyes the BCVA decreased by more than 1 line. One eye had recurrent CNV. In four eyes a cystoid macular oedema developed. No retinal detachment or disturbing diplopia was noted. Conclusions: In the present study, FMT in PDT-nonresponders stabilised or improved visual acuity in the majority of the eyes in a mean follow-up period of nearly 2 years. FMT can be considered as a therapeutical option in eyes who are nonresponders to the PDT in neovascular AMD.
