The most common type of overactive inferior oblique muscle is secondary to a delay in the development of superior oblique muscle function. Operative intervention is not indicated because as a child matures the overactivity of the inferior oblique muscle will gradually disappear. In those cases where surgery is performed, the desired effect of elimination of excess elevation is achieved indirectly. The theory that the inferior oblique muscle is not primarily an elevator is supported by this explanation involving an indirect surgical effect. An explanation of a common postoperative finding after unilateral recession of an inferior oblique muscle is presented. 相似文献

PURPOSE: Both anterior transposition and graded recession have been shown to be effective procedures in weakening the inferior oblique muscle. Anterior transposition may work in part by converting the inferior oblique muscle from an elevator to a depressor of the globe. In theory, this would be useful in treating the inferior oblique overaction associated with superior oblique paresis. We compared inferior oblique recession and anterior transposition for the surgical correction of Knapp's class III unilateral superior oblique paresis. METHODS: Four patients underwent 14 mm recession, and five underwent anterior transposition of the inferior oblique muscle for the hypertropia in superior oblique paresis. Prism cover test measurements were made in all cardinal fields of gaze and were compared before and after operation between the two groups. RESULTS: The mean preoperative hyperdeviation in the primary position was 12 prism diopters in the recession group and 15 prism diopters in the anterior transposition group. The mean postoperative hyperdeviation was 1 prism diopter in the recession group and 3 prism diopters in the anterior transposition group. Postoperative results in the inferior oblique field of action demonstrated a mean 3 prism diopter hypertropia in the recession group and a 2 prism diopter hypotropia in the anterior transposition group. CONCLUSIONS: Anterior transposition and graded recession gave similar results in correcting the primary position hyperdeviation in Knapp's class III superior oblique paresis. Both procedures also markedly improved the hyperdeviation in the field of action of the inferior oblique muscle and superior oblique muscle. However, anterior transposition was more likely to result in postoperative hypodeviation in upgaze. 相似文献

The tenotomy or tenectomy of an overactive superior oblique produces a similar effect as an elongation of the tendon. Its efficiency cannot be compared with the tenotomy or myotomy of an overactive inferior oblique or rectus muscle. No discernible underaction or complete paralysis of the superior oblique are to be feared, if the surgical indication and technique are correct. We prefer the tenotomizing of the overactive superior oblique to the recession of its insertion. Commonly, but still not always, the overaction of the superior obliques is associated with an A syndrome. Besides, the tenotomy and tenectomy of the superior oblique may be useful in true Brown's syndrome and as an additional procedure in cases of paralysis of the two elevators of one eye, During the past four years this operation was done 32 times on 24 patients. In none of these cases an insufficiency of the superior oblique was produced. 相似文献

PURPOSE: The purpose of this study was to determine the outcomes of surgical management in adult patients with unilateral superior oblique muscle palsy. MATERIAL AND METHODS: A retrospective review of 82 patients who underwent surgical correction at the Department of Strabismology, Cracow Eye Hospital over a 20 years period (1982-2003) was done. The patients were divided into 2 groups: congenital (group I) and acquired (group II) of superior oblique muscle palsy. Group I consisted of 43, group II of 39 patients. The mean age at surgery was 34 years in the congenital and 38 years in the acquired group. Preoperative and postoperative vertical deviation and excycloduction was measured in diagnostic positions of gaze using a major synoptoscope. RESULTS: There were a total of 97 operations: inferior oblique muscle recession was performed in 61 patients, superior oblique muscle tuck in 33, contralateral inferior rectus muscle recession in 1 patient, superior rectus muscle recession in 1 patient and inferior rectus muscle resection in 1 patient. 83% of patients underwent muscle surgery once, 16% were operated twice and 1 patient was operated three times. An average of 1.1 surgeries were performed per patient in the congenital group and 1.2 in the acquired group. In both groups, in all diagnostic positions of gaze, the mean preoperative vertical deviation in patients operated twice was found to be significantly greater than in patients operated once. There was no such relationship found for excyclotorsion. In both groups high and statistically significant correlation was found between the amount of vertical deviation and excyclotorsion before treatment and their reduction in the inferior oblique muscle recession group. For the superior oblique muscle tuck, such a relationship was found only in the acquired group. For both groups (congenital and acquired) recession of the inferior oblique muscle was found to be more effective than superior oblique muscle tuck in the reduction of vertical deviation and excyclotorsion for primary position, downward gaze and downward gaze in adduction. Only in upward gaze in adduction the superior oblique muscle tuck, proved to be more effective than inferior oblique muscle recession. Hypercorrection (vertical and torsional) was found only in the upper field of binocular gaze. Postoperative Brown's syndrome was found to be more frequent after a superior oblique muscle tuck than after recession of the inferior oblique muscle. The risk of postoperative Brown's syndrome after the superior oblique muscle tuck was particularly high in the congenital group. CONCLUSIONS: Recession of the inferior oblique muscle was found to be not only more effective but also safer than superior oblique muscle tuck. 相似文献

Surgical recession of the inferior oblique muscle is simpler to perform if the inferior rectus muscle, rather than either the lateral rectus muscle or the inferior oblique muscle insertion, is used as a landmark. We measured 200 consecutive autopsy eyes to determine the distance from the commonly used 8-mm recession site determined by the Fink technique to the lateral border of the inferior rectus muscle insertion. It was easier to reach this point by measuring 4.0 mm posterior and 4.4 mm superior to the lateral insertion of the inferior rectus muscle, or 2.9 mm superior (on a line parallel to the corneoscleral limbus) and 5.1 mm posterior (on the line perpendicular to the corneoscleral limbus) to the lateral insertion of the inferior rectus muscle. We made anatomical studies to grade the amount of inferior oblique muscle recession and to evaluate the proper placement of the posterior border of the recessed inferior oblique muscle. 相似文献

PURPOSE: We report the surgical results of marginal myotomy of a minimally overacting inferior oblique muscle in conjunction with traditional recession or myectomy of the greater overacting inferior oblique muscle in 10 patients with asymmetric bilateral superior oblique palsies and asymmetric inferior oblique overaction. METHODS: Ten consecutive patients with bilateral superior oblique palsies had a hypertropia in primary position (5-28 PD) and unequal inferior oblique overaction (0 to +2 in the lesser overacting inferior oblique muscle, +2 to +4 in the greater overacting inferior oblique muscle). Reversal of the hypertropia was noted in ipsilateral oblique upgaze. All patients underwent a recession or myectomy of the greater overacting inferior oblique muscle and a marginal myotomy of the lesser overacting inferior oblique muscle. RESULTS: Seven patients had no vertical deviation in primary position, 2 patients had a residual hypertropia of 2 to 3 PD, and 1 patient had a residual hypertropia of 8 PD. The abnormal head position present preoperatively in 8 patients was eliminated or greatly improved after surgery. Postoperatively all but 1 inferior oblique overaction was graded as 0 to trace. Mean follow-up time was 19 months (range, 1.5-68 months). CONCLUSIONS: In bilateral superior oblique palsies with asymmetric inferior oblique overaction, a mildly overacting inferior oblique muscle can be corrected by marginal myotomy, combined with a recession or myectomy of the greater overacting inferior oblique muscle. This procedure can reduce or eliminate the hypertropia in primary position while minimizing the possibility of residual inferior oblique overaction. 相似文献

PURPOSE: We wanted to examine the effect of graded recession and anteriorization of the inferior oblique muscle on patients suffering from unilateral superior oblique palsy. METHODS: Inferior oblique muscle graded recession and anteriorization were performed on twenty-two patients (22 eyes) with unilateral superior oblique palsy. The recession and anteriorization were matched to the degree of inferior oblique overaction and hypertropia. The inferior oblique muscle was attached 4 mm posterior to the temporal border of the inferior rectus muscle in six eyes, 3 mm posterior in five eyes, 2 mm posterior in five eyes, 1 mm posterior in five eyes, and parallel to the temporal border in one eye. RESULTS: The average angle of vertical deviation prior to surgery was 11.3 +/- 3.9 prism diopters (PD). The total average correction in the angle of vertical deviation after surgery was 10.8 +/- 3.8 PD. In the parallel group, the average reduction was 14 PD. After surgery, normal inferior oblique muscle action was seen in eighteen of twenty-two eyes (81.8%). CONCLUSIONS: Graded recession and anteriorization of the inferior oblique muscle is thought to be an effective surgical method to treat unilateral superior oblique palsy of less than 15 PD. 相似文献

BACKGROUND: Unilateral inferior oblique muscle weakening surgical procedures often lead to the appearance of inferior oblique muscle overaction in the contralateral eye. The purpose of this study was to determine how different types of unilateral inferior oblique muscle procedures affect the apparent function of the inferior oblique muscle in the contralateral eye. METHODS: A computer search was performed to locate all patients on the pediatric ophthalmology service at the Wilmer Ophthalmological Institute who underwent a unilateral inferior oblique muscle weakening procedure from 1980 to 1994. Only patients with a diagnosis of primary inferior oblique muscle overaction were included in the study. RESULTS: Fourteen patients met the inclusion criteria. One patient had undergone an anterior transposition of the inferior oblique muscle, seven patients had undergone a 10 mm recession of the inferior oblique muscle, and six patients had undergone a myectomy of the inferior oblique muscle. Before the operation,there was no difference in the inferior oblique muscle function of the contralateral eye among the three groups. However, after the operation apparent inferior oblique muscle overaction developed more frequently and to a greater degree in the contralateral eye among patients in the anterior transposition and 10 mm recession groups than among patients in the myectomy group. CONCLUSION: Either anterior transposition or 10 mm recession of the inferior oblique muscle may limit elevation in abduction in the eye on which inferior oblique muscle surgery was performed. The limitation of elevation in abduction may create apparent inferior oblique muscle overaction in the contralateral eye. 相似文献

PURPOSE: To evaluate the surgical results of correcting strabismus with inferior oblique hyperfunction. MATERIAL AND METHODS: A retrospective chart review of 40 patients, who underwent surgery from 1999-2001 was performed. 7 patients had isolated inferior oblique hyperfunction, 5 with hypertropia, 23 patients had esotropia with inferior oblique hyperfunction and 5 patients had exotropia with inferior oblique hyperfunction. The recession of inferior oblique muscle was undergone in cases with inferior oblique hyperfunction, sometimes in hypertropia with anteposito. The recession-resection of rectus muscles with myotomy-tenotomy of inferior oblique muscle or his recession usually were performed in cases with coexisting esotropia or exotropia. RESULTS: In all cases eyes were acceptably aligned. The recession of inferior oblique muscle is the most effective method of operation in high oblique hyperfunction. 相似文献
