“…Recessions of the contralateral medial rectus muscle are sometimes used, but the approach remains controversial, 2,13-15 with a paradoxical increase in head turn described in some cases. 16,17 Transposition procedures have been proposed as a means of increasing lateral force to the eye to compensate for the lack of lateral rectus muscle function. At present, full, augmented VRT 18 is a widely used approach.…”

Superior Rectus Transposition vs Medial Rectus Recession for Treatment of Esotropic Duane Syndrome

et al. 2014

Superior rectus transposition (SRT) with or without medial rectus recession (MRc) has been introduced as an alternative to MRc alone for treatment of esotropic Duane syndrome; however, the effectiveness of these procedures has not been compared previously.OBJECTIVE To compare the safety and efficacy of MRc and SRT in treatment of Duane syndrome. DESIGN, SETTING, AND PARTICIPANTSRetrospective medical record review of all patients with esotropic Duane syndrome who underwent surgical treatment from January 1, 2006, through December 31, 2012, in a multispecialty, hospital-based pediatric ophthalmology/adult strabismus practice at Boston Children's Hospital. Patients in the SRT group underwent SRT with or without MRc; those in the non-SRT group underwent unilateral or bilateral MRc.EXPOSURES Surgical treatment of esotropic Duane syndrome.MAIN OUTCOMES AND MEASURES Binocular alignment, ocular ductions, head position, stereopsis, and fundus torsion were recorded before surgery and at the 2-month and final postoperative visits. We also evaluated postoperative drift. RESULTSThe medical record review identified 36 patients who underwent 37 procedures, including 19 in the SRT group (13 SRT + MRc and 6 SRT alone) and 18 in the non-SRT group (11 unilateral MRc and 7 bilateral medial rectus resession). Mean MRc was smaller when performed with SRT (3.3 vs 5.3 mm; P = .004). Although the initial deviation was larger in the SRT group, both groups had a similar improvement in esotropia and head turn. Abduction improved by at least 1 unit in 15 of 19 patients in the SRT group (79%) vs 5 of 18 in the non-SRT group (28%). In 24 patients followed up for more than 6 months, mean esotropia decreased from 8.2 to 6.1 prism diopters (Δ) in the SRT group (n = 12) but increased from 7.2 to 10.9Δ in the non-SRT group (n = 12). CONCLUSIONS AND RELEVANCEThe combination of SRT and MRc was more effective than MRc or bilateral medial rectus resession at improving abduction while allowing for a smaller recession to align the eyes and eliminate a compensatory head posture. Although any surgery on the vertical rectus muscles should in theory increase the risk for vertical or torsional complications, to date this theory has not been borne out in our patients. Patients treated with SRT appear to have a reduced likelihood of long-term undercorrection. We therefore recommend SRT with adjustable MRc for treatment of Duane syndrome in patients with larger amounts of esotropia.

Objectives:To evaluate the results of symmetric and asymmetric surgery and responses to surgical amounts in patients with infantile esotropia.Materials and Methods:The records of patients with infantile esotropia who underwent bilateral medial rectus recession (symmetric surgery) and unilateral medial rectus recession with lateral rectus resection (asymmetric surgery) were analyzed. The results of the cases with symmetric (group 1) and asymmetric (group 2), successful (group 3) and failed (group 4) surgeries were compared, and responses to the amount of surgery were investigated.Results:There were no significant differences between group 1 (n=71) and group 2 (n=13) cases in terms of gender, refraction, preoperative distance deviation, anisometropia and postoperative deviation angles, binocular vision, surgical success or follow-up period (p>0.05). The rate of amblyopia, near deviation and amount of surgery were higher in group 2 cases (p<0.05). Between group 3 (n=64) and group 4 subjects (n=20), no significant differences were detected in terms of gender, surgical age, refraction, amblyopia, anisometropia, preoperative deviation angles, the number of symmetric and asymmetric surgeries, the amount of surgery, or postoperative binocular vision (p>0.05). The average postoperative follow-up period was 15.41±19.93 months (range, 6-98 months) in group 3 cases and 40.45±40.06 months (range, 6-143 months) in group 4 cases (p=0.000). No significant difference was detected in the amount of deviation corrected per 1 mm of surgical procedure between the successful cases in the symmetric and asymmetric groups (p>0.05).Conclusion:Symmetric or asymmetric surgery may be preferable in patients with infantile esotropia according to the clinical features. It is necessary for every clinic to review its own dose-response results.

PurposeTo evaluate the effects of bilateral inferior oblique transposition (BIOT) on horizontal deviation from primary position among patients with bilateral dissociated vertical deviation (DVD) associated with inferior oblique overaction (IOOA) in infantile strabismus.MethodsRetrospective chart review was conducted among 19 patients with infantile strabismus. All patients had DVD and IOOA with consecutive or recurrent horizontal deviation and underwent modified BIOT surgery. Patients were divided into three subgroups: patients who underwent BIOT (BIOT group, n = 9) alone, BIOT with medial rectus recession or lateral rectus resection simultaneously (ET BIOT group, n = 6), or BIOT with lateral rectus recession or medial rectus resection simultaneously (XT BIOT group, n = 4). Postoperative angle of horizontal deviation (prism diopter, PD) and corrected magnitude of horizontal deviation (PD) at final visit after surgery were analyzed in each group.ResultsThe mean age was 55.11 ± 21.05 months (range, 32 to 115). The mean follow-up period was 8.68 ± 2.87 months (range, 6 to 18). Preoperative horizontal deviation was 4.23 ± 5.99 PD (range, 0 to 16) in BIOT, −17.33 ± 6.76 PD (range, −30 to −10) in ET BIOT, and 17.50 ± 2.52 PD (range, 14 to 20) in XT BIOT. Esodeviation is represented by negative values. DVD and IOOA were reduced less than +1 in all patients. The corrected amount of horizontal deviation was 3.56 ± 5.18 PD (range, 0 to 16) in BIOT surgery alone and larger in XT BIOT (18.50 ± 3.41 PD) than in ET BIOT (12.33 ± 5.57 PD, p = 0.004).ConclusionsMinimal exodeviation was corrected by BIOT alone. In addition, secondary eso- or exodeviation at great magnitudes should be corrected with proper horizontal muscle surgery along with BIOT.
