“…The mean treatment effects at distance (60 D for DUT alone and 69 D for combined surgery) were the largest, to our knowledge, of previously reported vertical rectus transposition surgeries. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] DUT combined with maximum recession of the antagonist muscle may correct a large deviation (90 D -100 D ), as demonstrated in patients 3 and 7. As for patient 2, the ruptured muscle could have reattached to the globe and improved the duction deficit spontaneously.…”

“…23 Finally, it was reported that lateral positioning of the new insertion of the transposed tendons by posterior fixation or posterior intermuscular sutures increased the treatment effect in patients with abducens nerve palsy by augmenting the lever arm for abduction. [8][9][10][11] Similarly, DUT creates lateral positioning of the transposed tendons for approximately 5 mm at the near margin of the paralyzed muscle with the sutures anchored on the sclera adjacent to the opposite corner of the insertion. Postoperative vertical deviation is well known as a complication of vertical rectus muscle transposition.…”

“…The mean correction of this procedure was reported to be 42 D . 2 A number of modifications [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] have been proposed to increase the effect of the surgery while reducing the risk of complications such as anterior segment ischemia. Nevertheless, the expected surgical effects were not adequate to correct a deviation .60 D , which is sometimes associated with severely paralytic strabismus.…”

PURPOSETo describe our surgical outcomes using a novel muscle transposition procedure, or double-under muscle transposition (DUT), in the treatment of paralytic strabismus. METHODSIn this surgery, the split halves of the superior and inferior rectus muscles opposite the paralyzed muscle are disinserted, crossed under both the remaining half and the paralyzed muscle, and anchored at opposite corners of the insertion of the paralyzed muscle. The medical records of consecutive patients who underwent DUT were retrospectively reviewed. Outcome measures were angle of deviation and duction deficit. RESULTSSeven patients were included. Diagnoses included WEBINO (n 5 1), rupture of the medial rectus muscle (n 5 1), and abducens nerve palsy (n 5 5). DUT alone was performed in 3 patients; DUT combined with antagonist muscle recession, in 4 patients. One patient underwent the surgery bilaterally. Mean follow-up was 17 AE 181 months (range, 7-57). Preoperative angles of distance deviation ranged from 25 D to 142 D in magnitude. All except a single patient had duction limitation of grade À5. The mean change in distance deviation for DUT alone for each operated eye was 60 D AE 6 D (53 D -65 D ); for combined surgery, 69 D AE 23 D (range, 52 D -103 D ). Final mean angle of deviation at distance was 12 D AE 3 D (À4 D to 0 D ), although an additional surgery was required for large overcorrections in 2 patients. Duction limitation improved in all patients. One patient experienced a postoperative vertical deviation. CONCLUSIONSDUT may be an alternative for patients with severely paralytic strabismus not likely to resolve with previously reported muscle transposition surgeries. Overcorrection may occur in some cases.

A review of transposition techniques for treatment of complete abducens nerve palsy

Purpose: To review various types of extraocular muscle transposition procedures for management of strabismus in sixth cranial nerve palsy with little lateral rectus (LR) muscle function, along with their pros and cons. Methods: We performed a comprehensive review of transposition procedures in sixth cranial nerve palsy, based on literature published anytime up to March 2021. A thorough search through PubMed and Cochrane databases was performed. All types of clinical studies on different transposition procedures in LR palsy, were included. Results: Eighty-six original articles in English, with full text or abstracts available, were included in the review, among which 16 are prospective studies, 48 retrospective, 3 review articles, 1 randomized clinical trial, 17 case reports, and 1 letter. Vertical rectus transposition has demonstrated promising results, especially in abduction improvement and expansion of binocular diplopia-free visual field, albeit the possible adverse effects such as anterior segment ischemia, especially in the presence of medial rectus contracture, and induced vertical deviation may become troublesome. Partial muscle transposition, single muscle transposition, and also transposition without tenotomy have all been introduced to reduce the risk of multiple muscle manipulation and ischemia. On the other hand, different adjustable transpositions are being utilized to manage concomitant or induced vertical deviations. Conclusion: Transposition procedures are highly effective in the treatment of esotropia caused by complete LR palsy. Various techniques for vertical muscle transposition have been proposed, with each of them having certain advantages and disadvantages.

Several studies reported surgical outcomes for abducens nerve palsy, but information on factors that affect treatment success remains lacking. These factors are crucial for developing a treatment plan and providing disease counseling. This study aimed to investigate the outcomes of strabismus surgery for abducens nerve palsy and determine the factors that influence its success, including a review of relevant literature. Methods: This retrospective analysis included abducens nerve palsy cases, focusing on surgical interventions and relevant patient data, at the outpatient clinics of Phramongkutklao Hospital from April 1, 2012, to April 30, 2022. A relevant literature review included the surgical success rate and factors that influence surgical outcomes. Results: This study enrolled 32 patients, including 19 with partial and 13 with complete abducens nerve palsy. The overall success rate of strabismus surgery was 78.1%. Trauma was the leading cause of abducens nerve palsy in this population (28.13%). Fisher's exact and Mann-Whitney U-tests revealed that shorter abducens nerve palsy onset and smaller preoperative angle were significantly associated with successful surgical outcomes of strabismus surgery among the groups. In contrast, subgroup analysis revealed that only preoperative smaller angles were significantly associated with good surgical outcomes in horizontal strabismus surgery. However, the vertical rectus muscle transposition group demonstrated no significant factors. The literature review revealed that the success rate of surgery in abducens nerve palsy was 25%-82.6% for horizontal rectus muscle surgery and 46.2%-91% for rectus muscle transposition. Conclusion:The surgical success rate for abducens nerve palsy reached 78.1%, including 78.95% for partial and 76.92% for complete abducens nerve palsy. Notably, a shorter onset preceding surgery and a smaller preoperative angle significantly correlated with successful surgical outcomes one year postoperatively. Plain Language Summary: Numerous studies have been conducted to determine the effectiveness of eye muscle surgery for abducens nerve palsy. However, there is still a lack of information on the various factors that can influence the success rate of the treatment. Understanding these factors is crucial for developing appropriate treatment plans and guidance for individuals with this condition. Our study aimed to examine the effectiveness of strabismus surgery for abducens nerve palsy and identify the factors that affect its success. This was achieved by reviewing relevant literature and analyzing cases from Phramongkutklao Hospital between April 1, 2012, and April 30, 2022. We included 32 patients with partial or complete abducens nerve palsy, with trauma being the leading cause of the condition in our group. The results showed that the surgery was successful in 78.1% of cases. Our analysis revealed that getting surgery sooner after the palsy started and having a smaller misalignment angle before surgery were associated with better outcomes. However, the...
