PurposeTo compare the effects of graded anterior transposition with myectomy in primary inferior oblique overaction (IOOA).MethodsIn a randomized clinical trial study, patients entered into two groups: graded anterior transposition (Group 1) and myectomy (Group 2). In the myectomy method, 8 mm of the inferior oblique (lO) muscle was excised in the lower temporal side, and in the graded anterior transposition group, the IO muscle was recessed according to Wright's method. Patients were followed up for at least 1.5 months. IOOA was graded from 0 to +4. Surgical success was defined as reduced IOOA to a grade of +1 or less.ResultsIn a randomized clinical trial study, a total of 30 patients (60 eyes) were included in the study (32 eyes in Group 1 and 28 eyes in Group 2). Pre-operation IOOA was 3.18 ± 0.78 and 3.25 ± 0.70 in Groups 1 and 2, respectively. Mean IOOA in Group 1 and 2 was 0.95 ± 0.24 and 0.40 ± 0.10 at 6 months after the surgery, which means the mean correction of the overaction was statistically significant in both methods (P < 0.001). The success rate in the myectomy procedure was higher than graded recession. The weakening effect was better in higher grades of overaction (P < 0.001). The overall success rate of Groups 1 and 2 was 75% and 96.4%, respectively (P = 0.029).ConclusionsIn both groups, IOOA significantly decreased after the operation. The success rate of the myectomy procedure was found to be significantly higher than graded anterior transposition.

“…Moon and Lee, using the method of Guemes and Wright [ 11 ], reported IO muscle overaction in two eyes in which hypertropia developed in the opposite eye. They also reported the development of anti-elevation syndrome in patients who received 0 and 1-mm reattachments [ 20 ]. In the present study, none of the patients exhibited remaining head tilt or diplopia, although 4 patients in groups 2, 4, and 5 exhibited slight remaining hypertropia in the primary position, which was still categorized as a good outcome.…”

BackgroundSeveral inferior oblique (IO) weakening methods exist for correction of superior oblique palsy (SOP). A previously reported method involved recession and anteriorization according to IO overaction (IOOA) grade, which might be subjective and cause upgaze limitation and opposite vertical strabismus. Therefore, this study attempted to examine the efficacy of modified graded recession and anteriorization of the IO muscle in correction of unilateral SOP without resulting in upgaze limitation or opposite vertical strabismus.MethodsA total of 26 patients (male, 16; female, 10; age: 3–40 years) with SOP and head tilt or diplopia underwent modified graded recession and anteriorization. Patients were grouped by the position at which the IO muscle was attached inferior/temporal to the lateral border of the inferior rectus (IR) as follows: (1) 7.0/2.0 mm (4 patients), (2) 6.0/2.0 mm (3 patients), (3) 5.0/2.0 mm (3 patients), (4) 4.0/2.0 mm (11 patients), (5) 3.0/0.0 mm (2 patients), and (6) 2.0/0.0 mm (3 patients). Recession and anteriorization were matched to vertical deviation in the primary position at far distance. Remaining diplopia, head tilt, vertical deviation (≤3 prism diopter (PD), excellent; 4–7 PD, good; and ≥ 8 PD, poor), upgaze limitation, and opposite vertical strabismus were evaluated.ResultsThe average pre and postoperative 1-year vertical deviation angles in the primary position at far distance were 15.0 ± 5.6 PD and 1.2 ± 2.0 PD, respectively. At 1 year post-surgery, the vertical deviation angles were reduced by 6.8–21.0 PD from those at baseline. Few patients exhibited remaining head tilt, diplopia, upgaze limitation, or opposite vertical strabismus. Correction of hypertropia was excellent in 22 and good in 4 patients.ConclusionsModified graded recession and anteriorization of the IO muscle is an effective surgical method for treating unilateral SOP. It exhibits good results and reduces the incidence of opposite vertical strabismus.Electronic supplementary materialThe online version of this article (doi:10.1186/s12886-017-0422-6) contains supplementary material, which is available to authorized users.

“…Morris's study showed 52% of patients had no deviation 9 months after operation on the vertical rectus [25]. In Moon and Lee's study on 22 patients with superior oblique palsy who had inferior oblique recess the recess operation and remission rate during 12 months follow up was 91% [26]. In Hatz et al's [27] and Maruo and Kubota's studies [28], the rate of inferior oblique recess surgery was greater and the vertical deviation was more severe, and due to residual deviation cases needed a second operation on the vertical rectus muscle.…”

Early diagnosis and management of strabismus is needed to avoid complications such as amblyopia. In this retrospective cohort study we reviewed the profile and surgical outcome of vertical strabismus patients attending a clinic in Yazd city in the Islamic Republic of Iran. From the medical files of 265 patients, 19.2% were found to have pure vertical deviation and 80.8% had combined horizontal and vertical strabismus. Congenital causes were recorded for 83.0% of cases and 24.9% had a family history of strabismus. Hypertropia (91.7%) was more common than hypotropia (8.3%). There was a statistically significant relationship between age at onset and vertical strabismus. Female patients had a higher rate of congenital vertical strabismus than did male patients. There was no significant association between surgery outcomes and sex or age of onset of strabismus. Early diagnosis and management in affected families and screening of patients with strabismus family history is needed.
