【Abstract】 Objective To evaluate inferior oblique muscle myectomy in the management of superior oblique muscle palsy.Methods 17 patients with congenital superior oblique palsy undergone inferior oblique muscle myectomy were evaluated preoperatively and postoperatively(one year).The prism and alternate cover test measurements were made in all nine cardinal positions of gaze.Bielschowsky head tilt test was evaluated quantitatively befor and after the operation.Abnormal head positions were recorded.Results Abnormal head positions and hyperdeviation under 15 prism diopters of the involved eyes were recovedred.Eyes′ hyperdeviation above 15 prism diopters showed apparent residual overaction.Conclusion A myectomy is effective in patients with superior oblique muscle palsy when the direct antagonist is overacting and the hyperdeviation is under 15 prism diopters.更多还原
