Minimally invasive strabismus surgery (MISS) for rectus muscle transpositions.

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 eight 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 and 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 (SD 21.6) pdpt decreased to 2.3 (4.4) pdpt at 6 months (p<0.01). At 6 months, 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 in improving ocular alignment in patients with paralytic strabismus.
