“…These surgeries present risks of complications, amongst which the most common are: under-or over-correction, anterior segment ischemia, and other rare complications as perforation of the ocular globe and endophthalmitis (Hong et al, 2005). In order to minimize under-or over-correction, appropriate technique is necessary, as is a detailed understanding of the width and specific point of insertion of these muscles.…”

SUMMARY: Extraocular muscles are important references in strabismus surgery and in placement of intraorbital devices. We analyzed extraocular muscles morphometry and possible anatomical variances of 20 orbits. We report the length, width, and points of insertion of the extraocular muscles. No anatomical variations in length, width and points of insertion were found. With regard to the rectus muscles, it was found that the superior rectus and lateral rectus are the longest muscles and that the width difference between the superior and inferior rectus is greater than that between the medial and lateral rectus and that the point of insertion of the rectus muscles has a variable morphology. The superior oblique muscle was smaller in caliber than the inferior oblique, as consistent with previous anatomical studies. Knowledge of the detailed morphology of extraocular muscles is fundamental in strabismus surgery and represents a key factor for the innovation of surgical techniques and orbital procedures.

“…In many other reports, the duration of the follow-up after muscle transposition procedures for abducens palsy were within several years. [5][6][7] Because the long-term outcomes of the muscle transposition procedures were not reported, our report could be useful to clarify the long-term effectiveness of this surgery.…”

“…[1][2][3][4][5][6][7][8] However, the stability of the effectiveness long term has not been revealed because few reports have discussed follow-up for 10 years after a muscle transposition procedure for abducens palsy. [5][6][7] Therefore, we report long-term outcomes (410 years) of three cases that underwent a muscle transposition procedure due to abducens palsy.…”

Few reports have discussed long-term outcomes of muscle transposition procedures. In this study, cases with abducens palsy treated with a muscle transposition procedure were followed for 12, 25, or 26 years. The preoperative alignments were esotropia of 65 degrees, 47 prism dioptres (PD), and 24 PD, respectively. Orthophoria was postoperatively achieved in all cases. The postoperative alignment in one case deteriorated at 8 years postoperatively, although orthophoria were maintained in the other two cases. These findings indicate that it is possible that esotropia can recur even though orthophoria was maintained for several years postoperatively in some cases that underwent a muscle transposition procedure.

“…The same procedure was repeated to determine the angle of deviation of the right eye, while the left eye was fixating. As described by Hong et al [10] movement of the paralytic muscle was classified into 6 grades with a score from 0 to −5 as follows. Score −5: the eye cannot move in the direction of action of the paralytic muscle; score −4: the eye can just reach the midline while moving in the direction of action of the paralytic muscle; scores −3 to −1: the eye can pass the midline and achieve 25%, 50%, and 75%, respectively, of the rotation from the midline to the maximum rotation in the direction of action of the paralytic muscle; score 0: normal eye movement in the direction of action of the paralytic muscle.…”

Aims. To report outcomes of the simultaneous surgical correction of vertical rectus paralysis combined with moderate-to-large angle horizontal strabismus. Methods. If a preoperative forced duction test was positive, antagonist muscle weakening surgery was performed, and then augmented partial rectus muscle transposition (APRMT) + partial horizontal rectus recession-resection was performed 2 months later. If a preoperative forced duction test was negative, APRMT + partial horizontal rectus recession-resection was performed. Antagonistic muscle weakening surgery and/or conventional recession-resection of the horizontal and/or vertical muscles of the contralateral eye was performed 2 months later, as needed. Results. Ten patients with a mean age of 22.3 ± 13.0 years were included and mean follow-up was 7.1 months. The mean vertical deviation that APRMT corrected was 21.4 ± 3.7 PD (prism diopter). The absolute deviation in horizontal significantly decreased from a preoperative value of 48.5 ± 27.4 PD to a value of 3.0 ± 2.3 PD 6 months postoperatively. The movement score decreased from a value of −5 ± 0 preoperatively to a value of −2.7 ± 0.8 at 6 months postoperatively. Conclusion. For patients with complete vertical rectus paralysis combined with a moderate- to-large angle of horizontal strabismus, combined APRMT and partial horizontal rectus recession-resection is safe and effective for correcting vertical and horizontal strabismus.
