角膜塑形镜对间歇性外斜视合并近视患者术后双眼视功能重建的效果

目的：探讨配戴角膜塑形镜对间歇性外斜视合并近视性屈光不正患者术后双眼视功能重建的效果。

方法：前瞻性对照研究。选取2019-06/2020-12期间我院手术治疗的间歇性外斜视合并近视患者60例120眼，根据家属和患者的意愿，分别将术后配戴角膜塑形镜和单焦框架眼镜的患者分为治疗组(A组30例60眼)和对照组(B组30例60眼)，随访时间6mo。分别于术前、术后6mo观察两组患者的同视机三级视功能、Titmus近立体视功能。

结果：术前，A组与B组各观察指标均无差异(P>0.05)。术后6mo，间歇性外斜视患者术后眼位得到矫正的同时，双眼视功能获得明显改善； A组在融合范围、近立体视功能方面均优于B组(P<0.05)，两组同时视、同视机立体视功能均无差异(P>0.05)。

结论：间歇性外斜视术后患者双眼视功能较术前明显改善。配戴角膜塑形镜能够有效改善间歇性外斜视合并近视患者术后的双眼视功能。

Effect of orthokeratology lens on the postoperative binocular vision rebuilding in patients with intermittent exotropia combined with myopia

AIM: To investigate the effect of wearing an orthokeratology lens on postoperative binocular vision rebuilding in patients with intermittent exotropia combined with myopic refractive error.

METHODS: Prospective control study. A total of 60 patients(120 eyes)with intermittent exotropia and myopia who underwent surgical treatment in our hospital from June 2019 to December 2020 were selected. Patients who wore orthokeratology lenses or monofocal frame glasses after surgery were divided into a treatment group(group A)and a control group(group B)according to the wishes of patients and their families, with 30 cases(60 eyes)in each group, and they were followed-up for 6mo. The third level visual function and Titmus near stereoscopic visual function of the two groups of patients were observed before and 6mo after surgery.

RESULTS: There was no statistical significance in all observation indicators between group A and group B before surgery(P>0.05). After 6mo of surgery, patients with intermittent exotropia achieved significant improvement in binocular visual function and corrected eye position. Group A was superior to group B in terms of fusion range and near stereoscopic visual function(P<0.05). There was no statistical significance between the two groups in terms of simultaneous vision and stereoscopic visual function(P>0.05).

CONCLUSION: The binocular visual function of patients with intermittent exotropia after surgery has significantly improved. Wearing orthokeratology lenses can effectively improve binocular visual function in patients with intermittent exotropia combined with myopia after surgery.
