Purpose: To evaluate outcomes of one muscle surgery for treatment of congenital superior oblique palsy (SOP) with Knapp Class V. Methods: Medical records were retrospectively reviewed for the patients with the congenital SOP type V who underwent surgical treatment through one muscle surgery between July 2015 and September 2020. The surgical procedure was resection-recession on the contralateral inferior rectus muscle of the hypertrophic or paretic eye. Vertical alignment at nine cardinal gaze positions, and resolution of the abnormal head posture were evaluated pre- and postoperatively. The follow-up was scheduled regularly at postoperative day 1, 1 week, 1 month, and followed by 2-month intervals until 18 months. Results: Twelve patients were included in this study, with a mean age of 6.4 years (range from 3 to 10 years). The mean follow-up period was 10.5 months after surgery (range from 6 to 18 months). The average vertical deviation at primary position was 6.33△ ± 2.93△ preoperatively and 0.75△ ± 1.14△ postoperatively ( p < 0.05). The average vertical deviation at downgaze was 23.33△ ± 4.75△ preoperatively and 1.92△ ± 1.62△ postoperatively ( p < 0.05). All patients had an abnormal head position preoperatively. Postoperative results indicated that the patients’ abnormal head position had been improved significantly. Conclusions: The surgical procedure of resection-recession on a single inferior rectus muscle is a successful intervention for the correction of superior oblique palsy (SOP) with Knapp Class V.

Purpose: To evaluate the effectiveness of inferior oblique recession with contralateral partial temporal inferior rectus recession in patients with decompensated congenital unilateral superior oblique palsy (SOP) in correcting moderate vertical deviations in primary position. Methods: The medical records of patients with SOP who underwent inferior oblique recession with contralateral partial temporal inferior rectus recession were reviewed retrospectively. Vertical deviation in primary position, subjective torsion, diplopia, residual deviation, and the deviation decrease were evaluated. Results: Four patients (three males and one female, age range 29–56 years) with congenital unilateral SOP and mean vertical deviation of 21.0 ± 5.3PD (range 14–25D) in primary position were included. Mean correction of hypertropia in primary position with this technique was 15.5 ± 5.3PD (range 10–20PD). The mean hypertropia on gaze to the contralateral side changed from 30.0 ± 10.8D before surgery to 9.3 ± 7.9D after surgery. Torsion had a mean change of 4.8° of incyclodeviation. Preoperatively, all patients had head tilt and diplopia, which was resolved in all but one patient, who will need surgery. Patients were followed an average of 18 months. No adverse events were reported in any subjects. Conclusion: When performing recession of inferior oblique muscles in SOP associated to a full recession of the contralateral inferior rectus, there is a risk of overcorrection in those with moderate angles. Performing a partial recession in the contralateral inferior rectus eye corrected up to 20PD in primary position in our series, reducing this risk.

Purpose:To report the outcomes of superior oblique split tendon elongation in Brown’s syndrome.Methods:Charts of 17 consecutive Brown’s syndrome patients who underwent superior oblique split tendon elongation were reviewed and clinical data regarding preoperative, intraoperative, and postoperative data were collected.Results:About 17 eyes of 17 children with congenital Brown’s syndrome underwent superior oblique split tendon elongation between January 2012 and March 2020 by a single surgeon. Mean age at surgery was 5.47 ± 2.82 (range 1.50–13.2). Eight (47.1%) were female. Preoperative deficit of elevation in adduction was −4 in all children. At the end of surgery, all eyes were freely elevated on adduction, on forced duction test. Mean follow-up time of 26.24 ± 11.22 (range 11–53) months. In 15 of 17 children (88.2%), motility improved, orthotropia in primary position was achieved, and head posture eliminated ( p < 0.001). Superior oblique palsy occurred in two children, who after reoperation, achieved an acceptable outcome. No intraoperative complications were recorded.Conclusion:The superior oblique split tendon elongation procedure is a useful surgical technique with stable and satisfying outcomes for the treatment of severe congenital Brown’s syndrome.

Monocular elevation deficiency poses a challenge to strabismus surgeons on account of its varied clinical presentations as well as management which often needs a tailored approach. We report on a young child who presented to us at 6 months of age with a clinical course marked by primary involvement of the inferior rectus muscle in one eye causing restricted elevation in all gazes and complete relief of hypotropia following disinsertion of the affected muscle but followed by recurrence and additional procedures (antimitotic application and superior rectus plication) for the same. She followed a recalcitrant clinical course which was marked by multiple recurrences requiring a tailored approach and finally managed successfully with a follow-up of 3 years, by now. This case demonstrates the almost intractable nature of restrictive pathology involving a single muscle warranting multiple surgeries and a close follow-up with good surgical outcome.

Purpose: To investigate the changes in extraocular muscle thicknesses by variations in the thyroid stimulating antibody (TSAb) level in patients with thyroid eye disease (TED).Methods: A total of 67 TED patients were enrolled. They were divided into two groups: an experimental group with clinically significant elevated TSAb levels (≥140 IU/L) and a control group (TSAb <140 IU/L). All of the lateral, medial, superior, and inferior rectus muscle thicknesses were measured with the aid of anterior segment optical coherence tomography (OCT). The average thicknesses for both eyes were recorded for each patient based on the values measured at the ends of the muscles (which become vertically thinner from the points of tendon attachment). We measured changes in TSAb levels and extraocular muscle thicknesses after two follow-up periods and sought correlations among these parameters.Results: At the initial visits, the inferior rectus muscle thickness was positively correlated with the TSAb level in the experimental group (p = 0.045, r = 0.478). None of the medial, superior, or lateral rectus muscle thicknesses were so correlated. On follow-up, the variation in TSAb level correlated negatively with changes in lateral rectus muscle thickness (p = 0.038, r = -0.357). The superior rectus muscle thickness tended to be negatively correlated with the TSAb level, but statistical significance was not attained (p = 0.146, r = -0.669). The thicknesses of the inferior and superior rectus muscles did not change over time.Conclusions: In TED patients, TSAb variations seem to reflect the extent of periorbital tissue edema, thus correlating negatively with especially lateral rectus muscle thickness changes.

Purpose: To report our experience in the management of avulsion of the inferior rectus muscle. Methods: We describe the approach we have used for surgical repair of isolated avulsion of the inferior rectus muscle in two patients who suffered orbital trauma. Results: In both cases, the proximal portion of the inferior rectus muscle was located successfully by the generated muscle force duction test and sutured back into its original insertion point. Infraduction was normal and orthotropia was present in all directions of gaze during 1 year of postoperative follow-up in both cases. These favorable outcomes are attributed in part to the inferior rectus muscle pulleys system and the natural history of this type of injury, which allows the lost proximal portion to be identified by generated muscle force duction test. Conclusion: Generated muscle force duction test can be used to locate the proximal portion of a lost inferior rectus muscle and restore its function in patients with traumatic avulsion injury involving an extraocular muscle.
