“…Although several studies have examined simultaneous IO weakening and SO tendon tuck procedures, they deal either with acquired SOP [17, 18], or mixed origins [4]. In this study, we collected information on congenital/idiopathic SOP alone.…”

PurposeTo clarify the efficacy of a surgical strategy based on the superior oblique tendon traction test.MethodsA retrospective chart review was performed between January 2002 and June 2015. During that period, a single inferior oblique muscle (IO) myectomy and a combined IO myectomy and superior oblique muscle (SO) tuck procedure were performed based on SO tendon looseness as revealed by a traction test. The surgical effects of both procedures and the number of operations were analyzed.ResultsSixty-five cases were retrieved. Seventy-four surgeries were required. The IO myectomy and simultaneous groups included 48 and 17 cases, respectively. Pre-operative vertical deviation was significantly lower in the IO myectomy (11.8 prism diopters) than in the simultaneous (27.2 prism diopters; Mann–Whitney U-test, P < 0.001) group. The mean induced changes were 9.4 prism diopters and 21.6 prism diopters in the IO myectomy and simultaneous groups, respectively, and the postoperative vertical deviation was not significantly different. On average, 1.13 and 1.18 surgeries per patient were performed in the IO myectomy and simultaneous groups, respectively.ConclusionThe simultaneous surgery of inferior oblique myectomy and superior oblique tuck is safe and effective for treating large angle of congenital/idiopathic superior oblique palsy with a lax superior oblique tendon, as determined by the traction test.

Nasal transposition of the inferior rectus (IR) muscle, which is transposed nasally with the insertion parallel to the spiral of Tillaux, could correct excyclotropia. However, as far as we are aware, there have been no reports examining the surgical effects of this procedure in multiple cases. Therefore, we examined the surgical effects of IR nasal transposition in 135 cases with acquired trochlear nerve palsy at Hyogo College of Medicine Hospital, Nishinomiya, Japan. One muscle width of IR nasal transposition corrected an average 5.6° in excyclotorsion, while bilateral IR nasal transposition corrected average 10.9°. This result shows this procedure is accurate quantitatively. Moreover, IR nasal transposition in combination with IR recession or resection can correct vertical deviation and excyclotorsion simultaneously. The results of this study suggest that IR nasal transposition should become first-line treatment for acquired superior oblique palsy.

“…The graphical representation of FBSV shows that a FBSV was restored in primary position (l " Fig. 4) [3]. In the subgroup of the 20 patients for which a long-term follow-up was available, the median preoperative FBSV functional score was 13 % (range 0-84%), improved to 84 % (range 0-100 %) 6 months postoperatively, but slightly decreased to 72 % (range 0-100 %) at the last follow-up.…”
