Popis: Objective To study the long-term efficacy and the complications of several transposition techniques for the treatment of Duane syndrome. These included, full vertical rectus transposition, partial vertical rectus transposition, transposition without muscle disinsertion, and superior rectus transposition. Material and methods A retrospective study of the patients diagnosed with Duane syndrome, and who underwent any of the different transposition techniques associated or not to the medial rectus recession with a follow-up longer than 12 months. A good result was considered a final deviation ≤10 prism dioptres (pd) in primary position, anomalous head posture Results Seven cases were included (6 women, 6 unilateral), and a mean age of 37.71 years. Pre-operative central gaze esotropia of 28 ± 11.68 pd decreased to 6 ± 4.62 pd at the final visit (p = .009). The anomalous head posture decreased in 6 patients, and the abduction improved one degree from −3.14 to −2.14 (mean). An induced vertical deviation ≤8 pd was observed in 4 cases. None experienced diplopia at the final visit. The percentage of reoperations was 71.42%. Only 28.57% had a favourable outcome with a single surgery, which increased to 71.42% with further surgeries at the final follow-up. Mean evolution time was 52 ± 31.65 months. Conclusion Vertical rectus transpositions in DS with moderate or severe clinical signs have only been effective in a small percentage of the cases. Most of them required further surgeries to resolve the complications or the under-corrections.
