通过对５－１０岁６例双上斜肌隐蔽性麻痹患儿进行眼底照相，观察手术前后客观外旋转性斜视的变化。结果表明眼底照相能够判定双侧外旋转性斜视的存在，这有助于对临床上不易区分的双上斜肌隐蔽性麻痹和真正的单侧性上斜肌麻痹的鉴别诊断；并对指导手术设计、提高一次性手术成功率具有重要的实际意义。
The fundus photography was performed on 6 children with occult paralysis of the upper oblique between 5 and 10 years old, and the changes of objective external rotational strabismus before and after surgery were observed. The results show that fundus photography can determine the presence of bilateral lateral rotational strabismus, which contributes to the clinically indistinguishable bilateral upper oblique obscure paralysis and true unilateral superior oblique paralysis in the differential diagnosis; and guidance of surgery Design, improve the success rate of one-time operation has important practical significance.
