低度数儿童间歇性外斜视手术时机的选择

Choice of operating time of low degree intermittence exotropia in children

[目的]观察和分析低度数儿童间歇性外斜视与其手术时机的选择.[方法]观察30例低度数儿童间歇性外斜视的平均30个月自然经过,不用任何治疗.分析斜视度的变化及立体视觉的变化.[结果]发现其总体结果表明斜视度无明显恶化增大,立体视觉有所改善和提高.[结论]提出对于小于20△的儿童间歇性外斜视,其手术时机的选择,可在密切观察双眼视功能不减退时,能推迟手术数年以上.年龄较大时实施局麻手术,保证术后眼位正位的良好效果.

[Objective] To observe and analyse the relationship between the operating time and the low degree intermittence exotropia in children. [Methods] To observe 30 cases with low degree intermittence exotropia in children for 30 months without any treatment, and analyze the exotropia degree change and the stereoscopic vision change. [Results] The degree of exotropia of the cases has no increase in evidence and the stereoscopic vision is improved [Conclusion] When the degree intermittence exotropia of a child is less than 20△, the operating time can be put off to several years later, until the exotropia degree beyond 20△ and the stereoscopic vision down. When the child is older, an operation with local anesthesia can achieve a good result.
