目的:探讨斜视类型对术后远、近立体视恢复的影响。
方法:选取72例不同类型斜视患者,按斜视类型分为四组:组1为非调节性内斜视,组2为间歇性外斜视,组3为恒定性外斜视,组4为外斜V征伴下斜肌亢进。手术前后分别应用同视机检查远立体视。采用颜少明编绘的《立体视觉检查图》检查近立体视锐度。记录并分析术前、术后第7d,1、3、6mo的各项检查数据。
结果:斜视患者72例术后远、近立体视的恢复较术前有明显改善,其差异有统计学意义(P<0.05)。间歇性外斜视组术后远、近立体视的恢复优于非调节性内斜视组、恒定性外斜视组及外斜V征伴下斜肌亢进组,其差异有统计学意义(P<0.05)。非调节性内斜视组、恒定性外斜视组和外斜V征伴下斜肌亢进组术后不同时期远、近立体视的恢复差异无统计学意义(P>0.05)。远立体视(0例)比近立体视(19例,26%)的损害更严重,术后近立体视(51例,71%)的恢复明显优于远立体视(17例,24%),术后1mo远、近立体视恢复效果明显。
结论:不同斜视类型对术后远、近立体视恢复的影响存在差异,间歇性外斜视术后远、近立体视的恢复效果最佳。非调节性内斜视、恒定性外斜视和外斜V征伴下斜肌亢进对术后远、近立体视的恢复影响一致。斜视患者远立体视损害较重,术后近立体视恢复明显优于远立体视。 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

We report three patients with acquired bilateral superior oblique paresis who had bilateral modified Harada-Ito procedures, which resulted in significant incyclotorsion (ranging from 6 degrees to 19 degrees ) on the first day postoperatively. For Case 1 this was the only procedure, while Cases 2 and 3 also underwent simultaneous bilateral inferior oblique weakening. This overcorrection decreased spontaneously over the following 8 months to leave all patients asymptomatic. One patient returned 8 years following the initial surgery with symptoms of diplopia and recurrence of excyclotorsion. 相似文献

Background: The Fells modification of the Harada-lto procedure is usually performed bilaterally for the correction of excyclotorsion secondary to acquired bilateral superior oblique paresis. Excyclotorsion is not usually a major complaint in true unilateral superior oblique paresis. Occasional cases, however, may find this symptom bothersome and it may interfere with fusion. The purpose of the present study is to determine the effect of the unilateral modified Harada-lto procedure on the correction of symptomatic excyclotorsion in unilateral superior oblique paresis. Method: A retrospective case-note review of patients with unilateral superior oblique paresis undergoing unilateral modified Harada-lto procedures during the five-year period 1988-1993 was performed. Results: Six patients fulfilled the inclusion criteria. Superior oblique paresis was congenital in one case, secondary to trauma in two cases and idiopathic acquired in three cases. There were four males and two females aged from 25 to 63 years and all but one had previous surgery. The mean pre-operative excyclotorsion was approximately 10 degrees (range 8-14 degrees). Mean post-operative excyclotorsion was 3 degrees (range 2 degrees incyclotorsion -10 degrees excyclotorsion). Conclusion: The unilateral modified Harada-lto procedure is an effective surgical treatment of excyclotorsion resulting from superior oblique paresis and may improve sensory and motor fusion. 相似文献

AIM: To compare the changes in excyclotorsion after inferior oblique (IO) recession in patients with primary and secondary inferior oblique overaction (IOOA). METHODS: We retrospectively analyzed the data obtained from patients with IOOA who underwent graded IO recession. The patients were followed up for at least 3mo after surgery. Fundus photographs were taken pre- and postoperatively, and the sum of the angles of torsion in both eyes was used to analyze changes in excyclotorsion. Patients were divided into two groups: those diagnosed with primary IOOA were enrolled in the 1''IOOA group, and those diagnosed with secondary IOOA caused by superior oblique palsy (SOP) were enrolled in the 2''IOOA group. Excyclotorsion before and after surgery were compared between the two groups. RESULTS A total of 78 patients were enrolled in this study: 34 eyes in the 1''IOOA group and 44 eyes in the 2''IOOA group. In the 78 patients, torsional angle significantly decreased from 15.31±7.40 degrees (°) to 12.11±6.53° after IO recession (P<0.001). Mean preoperative torsional angle was larger in the 2''IOOA group than in the 1''IOOA group (P=0.03). In both groups, excyclotorsion significantly decreased after IO recession. (P=0.001 and P<0.001, respectively), however there was no significant difference in the amounts of changes in excyclotorsion between the two groups. CONCLUSION: Excyclotorsion was significantly larger in secondary IOOA than in primary IOOA, and a significant decrease in the torsional angle occurred after IO recession in both types of IOOA. 相似文献

Torsional diplopia developed in a 41-year-old man after he sustained severe head trauma and bilateral paralysis of the superior
oblique muscles. Funduscopy revealed bilateral excyclotorsion. The patient underwent a modified Harada-Ito operation in both
eyes. Fundus photographs showed bilateral excyclotorsion preoperatively and correction to the normal position after surgery.

The differences in the clinical and diagnostic characteristics of 33 consecutive traumatic unilateral (21 patients, 62% ) and bilateral (12 patients, 38%) superior oblique palsies were studied. The unilateral palsies had a large hypertropia in primary postion, more vertical than torsional diplopia, a compensatory head tilt to obtain fusion, and a positive Bielschowsky head tilt test. In contrast, the bilateral palsies had small hypertropias in primary gaze that alternated on right and left gaze, a large V-pattern esotropia with excyclotorsion that was frequently bilateral, and a compensatory head position with fusion in upgaze. The results of the study indicate that a V-pattern in excess of 25 prism diopters, an excyclotorsion of greater than 10 degrees, or head trauma severe enough to cause loss of consciousness should also signal bilateral involvement. Torsional diplopia was present in only 20% of unilateral palsies vs 75% of bilateral palsies. The Bielschowsky head tilt test was diagnostic in 100% of the patients with unilateral palsy and 83% of the patients with bilateral palsy. It was undiagnostic in the supine position in all patients. Spontaneous resolution occurred in 65% of the unilateral palsies but in only 25% of the bilateral palsies. Surgical correction was successful in relieving persistent symptoms. 相似文献

Traumatic rupture of the superior oblique muscle is rare. We report a case of a 54-year-old man injured by the metal hook of a hanger, resulting in a rupture of the superior oblique muscle tendon. He complained of torsional diplopia when in the primary position. The distal margin of the superior oblique muscle was reattached to sclera 5 and 9 mm apart from the medial insertion of the superior rectus muscle. One week after the operation, torsional diplopia disappeared. However, a 4-prism diopter ipsilateral hypertropia was observed. Three months later, hypertropia gradually increased to 20 prism dioptors and the second operation was done to correct vertical diplopia. 相似文献
