自1929年White等报告20例下斜肌作用不足的病例以来,下斜肌麻痹在文献中很少受到注意,发生率较小,有时难以诊断和治疗。最近Scotta等(1977)报道8例单独下斜肌麻痹,其中6例作上斜肌肌腱切断治疗,术后症状改善。本文介绍4例下斜肌麻痹,均作垂直肌手术治疗。病例1,男性29岁,右眼偏斜5年,向右看时出现复视。头偏向左,内收时左眼上转受限。右上斜20△,头向右偏时上斜加重,头偏左时无上斜,Tensilon试验阴性,术时牵拉试验阴性。作右上直肌后退5mm。9个月后上隐斜2△,无
Since 1929 White et al reported 20 cases of inferior oblique muscle function since inferior oblique muscle paralysis in the literature seldom get attention, the incidence is small, and sometimes difficult to diagnose and treatment. Recently Scotta et al. (1977) reported 8 cases of inferior oblique oblique paralysis alone, of which 6 cases were treated by oblique tendon tenotomy, postoperative symptoms improved. This article describes 4 cases of inferior oblique muscle paralysis, were treated for vertical muscle surgery. Case 1, male 29 years old, right eye deflected 5 years, diplopia appear to the right. Head to the left, adduction when the left eye up limit. Right upper tilt 20 △, head tilt to the right when the partial deviation, head tilt when the upper left oblique, Tensilon test negative, pull test when surgery was negative. For the upper right rectus muscle back 5mm. After 9 months on the phoria 2 △, no
