AIMS: To assess the results of visual axis alignment following one stage adjustable suture surgery to correct vertical diplopia. METHOD: Eight patients with a mean age of 44.9 years (range 16-80 years) complaining of vertical diplopia underwent rectus muscle recession under local anaesthesia with intraoperative adjustment of sutures. Diplopia was secondary to superior oblique paresis in four patients, dysthyroid eye disease in two patients, superior rectus paresis in one patient, and one developed a consecutive deviation after previous squint surgery. The surgery consisted of seven single muscle recessions (six inferior recti and one superior rectus) and one two muscle recession (inferior and lateral recti). The surgery was performed under topical anaesthesia supplemented with a subconjunctival injection of local anaesthetic over the muscle insertions. RESULTS: The patients remained comfortable throughout their surgery. All had a reduction in their vertical deviation. Six were asymptomatic and were eventually discharged. One had residual diplopia which was well tolerated without further intervention. One had persistent troublesome diplopia which was corrected by temporary Fresnel prisms. He became asymptomatic after further surgery of a 1 mm inferior rectus advancement. CONCLUSION: One stage adjustable suture surgery is recommended in all cases of strabismus surgery when postoperative results would otherwise be unpredictable. 相似文献

The authors present a group of 3500 patients treated surgically in the years 1961-1986 for disturbances of function of the oblique muscles. Two forms of these disturbances are discussed. The first one--acquired paresis of the trochlearis muscle, most frequently a sequelae of injury, the second one--congenital disturbances of action of the superior oblique, with hyperfunction of the inferior oblique, determined as "strabismus sursoadductorius". When the healthy eye was the master eye one the authors performed operations weakening the inferior oblique which was in hyperfunction (recession, partial marginal tenotomy, myectomy, elongation) or they strengthened the superior oblique (plication) because of its paresis. In patients with the affected eye as the master one they weakened the opposite inferior rectus (recession) or strengthened the opposite superior rectus (resection). In cases of a coexistence of a horizontal deviation also this deviation was treated surgically. Five thousand seven hundred four operations had been performed. The vertical deviation was corrected in 75.5 p.c. and diminished in 24 p.c. Binocular single vision without compensatory positioning of the head was attained in 55.4 p.c. of patients, with a small compensatory positioning of the head--in 10.8 p.c. 相似文献

PURPOSE: We wanted to determine the mechanisms of motor vertical fusion in patients with superior oblique paresis and to correlate these mechanisms with surgical outcomes. METHODS: Ten patients with superior oblique paresis underwent 3-axis, bilateral, scleral search coil eye movement recordings. Eye movements associated with fusion were analyzed. RESULTS: Six patients had decompensated congenital superior oblique paresis and 4 had acquired superior oblique paresis. All patients with acquired superior oblique paresis relied predominantly on the vertical rectus muscles for motor fusion. Patients with congenital superior oblique paresis were less uniform in their mechanisms for motor fusion: 2 patients used predominantly the oblique muscles, 2 patients used predominantly the vertical recti, and 2 patients used predominantly the superior oblique in the hyperdeviated eye and the superior rectus in the hypodeviated eye. The last 2 patients developed the largest changes in torsional eye alignment relative to changes in vertical eye alignment and were the only patients to develop symptomatic surgical overcorrections. CONCLUSION: There are 3 different mechanisms for vertical fusion in individuals with superior oblique paresis, with the predominant mechanism being the vertical recti. A subset of patients with superior oblique paresis uses predominantly the superior oblique muscle in the hyperdeviated paretic eye and the superior rectus muscle in the fellow eye for fusion. This results in intorsion of both eyes, causing a large change in torsional alignment. The consequent cyclodisparity, in addition to the existing vertical deviation, may make fusion difficult. The differing patterns of vertical fusional vergence may have implications for surgical treatment. 相似文献

In the paper we studied 87 patients with vertical or combined deviations treated in Eye Clinic from Cluj-Napoca between 1994-1998. The most patients show vertical deviation due to inferior muscle overaction (70 patients). 17 patients had a vertical deviation due to another causes (superior oblique paresis, III-nerve paresis and dissociated vertical deviations). We treated vertical deviation due to superior oblique muscle overaction only when was an important deviation in the primary position of gate. In superior muscle paresis we did a superior oblique muscle resection or weaken of inferior oblique muscle secondary overacting. In III-nerve paresis with contralateral superior rectus muscle overaction we did recession of this muscle. The results are favourable: the deviation disappear in the primary position of the gaze and decrease or disappear in the lateral gaze. 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
