Background/aims Long-term data of macular translocation for choroidal neovascularisation (CNV) secondary to age-related macular degeneration is lacking. Therefore, we describe the 3-year acuity outcomes.
Methods This is a retrospective, interventional case series consisting of 40 consecutive patients who underwent translocation between 2003 and 2008. Best-corrected visual acuity (BCVA) at the most recent follow-up visit was compared to that of the 1 year and pre-operative visits. Delayed post-operative complications were recorded, as diagnosed by clinical examination, spectral-domain optical coherence tomography, fundus autofluorescence imaging and angiography.
Results The mean (range) follow-up duration was 37.6 months (range 12.4–67.4 months). Median BCVA values were 0.80, 0.70 and 0.78 log(MAR) at the baseline, 1 year and most recent visits (p=0.13). A three-line gain in BCVA was seen in 12 (30%) patients at 1 year and 10 (25%) patients at the last observation. Twenty-seven (68%) patients achieved a BCVA of 6/60 or better and six (15%) patients, 6/12 or better at the final visit. In the subset of the cohort followed for two or more years, 24 of 32 patients (75%) achieved a BCVA of 6/60 at 1 year but six of these (25%) lost two lines of BCVA thereafter due to recurrent CNV, idiopathic macular oedema, macular hole or macular pucker. Recurrent CNV developed in nine patients (23%) within the first 2 years and their final mean VA was 6/30.
Conclusions With close post-operative monitoring and early treatment of delayed complications, 25% of this cohort maintained a three-line gain in acuity at 3 years after macular translocation.
