摘要
目的:本研究探讨了间歇性外斜视单眼闭塞后不同距离外斜视角度的变化及一组外斜视角度增加的特征。方法:共纳入102例诊断为原发性间歇性外斜视的患者。在33 cm, 3 m, 6 m, 12 m和6 m处使用镜面测量偏差角。此外,在非优势眼补片1小时后,在33 cm和3 m处测量偏差。咬合后33 cm偏角较高的患者被归类为“增加组”,而偏角较低的患者被归类为“平稳组”。结果:男女比例为46:56,平均手术年龄为9.23岁。在3、6、12和6 m处使用镜面进行偏差测量时,没有观察到显著差异。然而,闭塞后,偏差明显增加到33 cm (<i>p</i>& lt;0.01)。升高组近立体视敏平均对数为1.96±0.35,静止组平均对数为2.16±0.41。咬合后近偏度增加组近立体视力明显改善(<i>p</i>= 0.01),近Worth 4点测试中良好结果的比例增加(<i>p</i>= 0.03)。结论:术前测量单眼闭塞1小时后的最大偏差有助于减少复发和矫正不足,特别是对融合能力良好的患者。
Changes in Angle of Exodeviation According to Distance after Monocular Occlusion in Intermittent Exotropia
Purpose: This study investigated changes in the angle of exodeviation at different distances and the characteristics of a group that showed an increased angle following monocular occlusion in intermittent exotropia.Methods: In all, 102 patients diagnosed with basic intermittent exotropia were enrolled. The deviation angle was measured using a mirror at 33 cm, 3 m, 6 m, 12 m, and 6 m. Moreover, the deviation was measured at 33 cm and 3 m after patching the non-dominant eye for 1 hour. Patients with a higher deviation angle at 33 cm after occlusion were categorized as the ‘increased group’, whereas those with lower deviation angles were classified as the ‘stationary group’.Results: There was a male-to-female ratio of 46:56 and an average age at surgery of 9.23 years. No significant differences were observed in deviation measurements taken at 3, 6, 12, and 6 m using a mirror. However, after occlusion, there was a significant increase in deviation at 33 cm (p < 0.01). The average log value of near stereoacuity was 1.96 ± 0.35 in the increased group and 2.16 ± 0.41 in the stationary group. The group with an increased near deviation after occlusion demonstrated a significantly improved near stereoacuity (p = 0.01) and an increased proportion of good results in the near Worth 4 dot test (p = 0.03).Conclusions: Preoperative measurement of maximum deviation after 1 hour of monocular occlusion can help reduce recurrence and insufficient correction, particularly in patients with good fusional ability.
