“…Meanwhile, although not statistically documented by this study, outcomes from previous studies showed that patients treated with graded SO weakening procedures probably would have a reduced likelihood of developing a long-term deterioration of vertical movement resulted from iatrogenic SO palsy. 12,20 Furthermore, the correlation between the corrected magnitude of SOOA and the dosage of the suture lengthening demonstrated a good dose-response relationship of the SOSL procedure. Given the fact that the degrees of SOOA in SOSL group were in the range of 0 to +1 postoperatively in most (93%, 26/28) of the eyes, we therefore recommend our surgical dosage as stated above.…”

Purpose: Literature regarding different superior oblique (SO) weakening procedures showed variable results. Here, we aim to evaluate the effect of a novel superior oblique tendon suture lengthening (SOSL) procedure on weakening of SO in patients with A-pattern exotropia associated with dissociated vertical deviation and SO overaction (triad exotropia). Methods: The medical records of triad exotropia patients who underwent SOSL or SO tenotomy were reviewed. Surgical results of SOSL procedure mainly regarding the correction of A pattern, SO overaction, and fundus intorsion were analyzed and compared with those of SO tenotomy procedure. Results: SOSL demonstrated comparable efficacy in correction of A pattern (20.2△ ± 10.7△ vs 29.2△ ± 16.1△, p = 0.172), normalization of SO overaction (1.9 ± 0.9 vs 2.4 ± 1.5, p = 0.349), and conversion of fundus intorsion (11.1° ± 7.0° vs 11.3° ± 4.4°, p = 0.691) as SO tenotomy. Moreover, the success rate of A pattern collapse was significantly higher in the SOSL group than in the SO tenotomy group (86% vs 40%, p = 0.028). None of the patients in the SOSL group, but two in the SO tenotomy group, presented SO palsy postoperatively. In the SOSL group, the corrected magnitude of SO overaction strongly correlated with the dosage of suture lengthening ( p < 0.001). Conclusion: SOSL procedure could effectively eliminate the clinical manifestations associated with SO overaction. The graded dosage of SOSL leads to more controllable and predictable results compared to SO tenotomy, which makes SOSL a good alternative choice for SO weakening.

“…Graded procedures allow the precise localization of the tendon if additional surgery is required. 1,8,[17][18][19][20][21][22][23][24][25][26] Complications resulting from graded procedures include persistent vertical deviation in primary position, downshoot in adduction, underelevtion in adduction, scarring, limitation to downward rotation of the eye, and foreign body extrusion. [27][28][29][30] Posterior tenotomy and tenectomy moderately and selectively weaken the SO medial and posterior fibers, whose actions are abduction and depression leaving the anterior torsional fibers intact.…”

“…At present, the surgical treatment of this syndrome has been undergoing an evolution towards more effective procedures with fewer operative interventions [6, 17]. Wright [17]has introduced a procedure of superior oblique muscle tenotomy by inserting a segment of a 240 retinal silicone band, between the cut ends of a nasal tenotomy to elongate the tendon, to reduce the incidence of reoperation [18]. With this technique, results in true Brown’s syndrome have been excellent, yielding success rates that approach 90% [16, 19].…”
