ABSTRACT
The purpose of this study is to evaluate retrospectively the surgical results and complications in the patients with unilateral superior oblique palsy using superior oblique plication(SO plication) only or SO plication combined with inferior oblique weakening. Among 22 patients with unilateral superior oblique palsy, there were 13 patients(59.1%) in type III, 5 patients(22.7%) in type IV, 2 patients(9.1%) in type II and 2 patients(9.1%) in type V according to Knapps classification. The mean amount of hypertropia was 18 prism diopters(PD) and 18 of 22 patients(81.8%) showed abnormal head posture(AHP). Nineteen patients (86.4%) showed horizontal strabismus and exotropia was most common. The methods of oblique and vertical rectus operation were SO plication, SO plication combined with inferior oblique weakening, combined with resection of inferior rectus, and combined with recession of contralateral inferior rectus, inferior oblique weakening, and superior rectus weakening. We performed corrective surgery on the patients with horizontal deviation more than 14 PD. Postoperatively the mean amount of hypertropia was 2.6PD. In 7 patients with superior oblique plication only the mean amount of correction in plication was 8.4PD, and hypertropia was corrected 1.2PD per mm. Thirteen of 18 patients(72.2%) with AHP and 15 of 19 patients (78.9%) with horizontal strabismus were corrected after operation. Postoperative complications were residual hypertropia in 7 patients(31.8%) and Brown syndrome in one. We conclude that plication of the superior oblique may be one of the effective procedures for correction of superior oblique palsy and possible its complications may be postoperative undercorrection and Brown syndrom.
