方法：选取2017-01/2021-03于我院眼科接受手术治疗的68例136眼手术成功的恒定性外斜视患者作为本次研究对象，根据是否给予围手术期同视机闪烁训练，将其分为A组(同视机闪烁训练)35例70眼，B组(无同视机闪烁训练)33例66眼。A组患者年龄为13～62(平均29.34±12.72)岁，男19例38眼，女16例32眼； B组患者年龄为17～56(平均30.12±8.75)岁，男13例26眼，女20例40眼。术后1mo对患者进行同视机检查，比较两组患者的同时视功能、融合功能以及立体视功能的恢复情况。

结果：两组患者年龄、性别、术前远近斜视度比较均无差异(P>0.05)。术后1mo的同视机检查显示同时视功能、融合功能以及立体视三级功能恢复率，A组分别为54%、54%、43%，B组分别为27%、27%、15%，两组比较均有差异(χ²=5.117、5.117、6.280，均P<0.05)。

结论：对无双眼视功能的恒定性外斜视成人和大龄儿童(>12岁)患者进行围手术期同视机闪烁训练可有效改善患者双眼视功能，提升手术的治疗效果。

METHODS: We retrospectively reviewed 68(136 eyes)patients with constant exotropia, who successfully underwent surgical ophthalmological treatment from January 2017 to March 2021. Patients were divided into group A(n=35 cases, 70 eyes)and group B(n=33 cases, 66 eyes)according to whether or not they received perioperative synoptophore scintillation training. Group A included 19 males(38 eyes)and 16 females(32 eyes)(mean age: 29.34±12.72 years). Group B included 13 males(26 eyes)and 20 females(40 eyes)(mean age: 30.12±8.75 years). One month postoperatively, the patients were examined with a synoptophore, and the restoration of simultaneous vision, fusion function, and stereoscopic function were compared between the two groups.

RESULTS: There were no significant differences in age, sex, and preoperative far and near deviations between the two groups(P>0.05). Postoperatively, the restoration rates of simultaneous vision, fusion function, and stereoacuity were 54%, 54%, and 43% in group A, respectively. And 27%, 27%, and 15% in group B, respectively. Statistically, there were respectively significant differences between the two groups(χ²=5.117, 5.117, 6.280; all P<0.05).

CONCLUSION: Perioperative synoptophore scintillation training can effectively improve the binocular vision function of adult patients and older children(>12 years)with constant exotropia without binocular vision function and enhance the therapeutic effect of surgery.
