目的评估间歇性外斜视手术治疗的疗效。方法手术治疗的间歇性外斜视患者65例,术后观察正位率、眼位回退量以及近立体视的变化并比较评估。结果共65例间歇性外斜视患者,术后第1周正位率56人(86.2%),有效率100%;术后第1周较第1天眼位回退1.78~Δ±0.96~Δ,P=0.004。术后远期眼位的正位率为42.3%,有效率88.5%,远期眼位回退量7.65~Δ±6.76~Δ,较术后第1天差异明显,P=0.000。术后近立体视均有不同程度的改善,提高率为73.1%。结论手术治疗间歇性外斜视有助于眼位和立体视的改善,但术后眼位回退仍不容忽视,其原因受多方面因素影响。
Objective To evaluate the efficacy of intermittent exotropia surgery. Methods Sixty-five patients with intermittent exotropia treated surgically were enrolled in this study. The postoperative positive rate, retrograde eye volume and near stereopsis were evaluated and compared. Results A total of 65 patients with intermittent exotropia had a positive rate of 56% (86.2%) at the first week after operation, with an effective rate of 100%. In the first week after operation, = 0.004. Postoperative long-term eye position was 42.3%, effective rate 88.5%, long-term displacement of 7.65 ~ Δ ± 6.76 ~ Δ, compared with the first day postoperative significant difference, P = 0.000. Near stereopsis after surgery had different degrees of improvement, the improvement rate was 73.1%. Conclusions Surgical treatment of intermittent exotropia contributes to the improvement of ophthalmic and stereopsis, but the postoperative ophthalmic regression can not be ignored, the reason is affected by many factors.
