Aims: To present two similar, minimally invasive strabismus surgery (MISS) techniques for rectus muscle transpositions.
Methods: The technique and results of 10 consecutive MISS muscle transpositions performed in 8 patients by applying only small radial cuts between the insertion of the weak rectus muscle and the adjacent rectus muscles are presented.
Results: In nine eyes a minimal, in one eye a moderate lid and conjunctival swelling could be seen on the first postoperative day. The preoperative deviation at distance of 41.7+/-21.6 pdpt decreased to 2.3+/-4.4 pdpt at 6 month (p<0.01). At 6 month, only one patient had an abnormal head posture at distance and no patient experienced diplopia.
Conclusions: This study demonstrates that small-incision, minimal dissection transposition techniques are feasible and effective to improve ocular alignment in patients with paralytic strabismus.
