Absence of each of the extraocular muscles as a rare cause of strabismus has been reported. Helveston suggests that a significant horizontal deviation with suppression and/or amblyopia in a patient with the preoperative diagnosis of congenital superior oblique palsy should alert one to a possible absence of the superior oblique tendon. We present and discuss two patients with craniofacial dysostosis in whom extensive surgical exploration showed an absence of the superior oblique tendon.
据报道，眼外肌缺如作为斜视的罕见病因已被发现。赫尔夫斯顿指出，对于术前诊断为先天性上斜肌麻痹的患者，若出现显著的水平斜视并伴有抑制和/或弱视，则应警惕可能存在上斜肌腱缺如的情况。我们展示并讨论了两名患有颅面骨发育不全的患者，经广泛手术探查发现他们存在上斜肌腱缺如的情况。
