: To assess the correlation between the contribution rates of fusional convergence from the dominant and non-dominant eye and suppression depth and exotropia control. : Cross-sectional prospective study. : The fusional convergence of 25 participants with intermittent exotropia (mean age 10.8 ± 3.4; range 6-18 years) was measured with an eye-tracking system. The contribution rate was defined based on the amplitude of fusional convergence during refusion relative to the exo-deviation angle. The suppression depth was assessed, and exotropia control was evaluated using the intermittent exotropia Office Control Score. We analyzed the correlations between the contribution rate from the dominant and non-dominant eyes and the suppression depth or control score. : There was a negative correlation between the dominant eye's contribution rate and the suppression depth in both eyes ( = -0.85, 95% confidence interval [CI]: -0.97 to - 0.20 in the fixated dominant eye and = -0.91, 95%CI: -0.95 to - 0.40 in the fixated non-dominant eye). There was a negative correlation between the dominant eye's contribution rate and the control score at a 4-meter distance ( = -0.53, 95%CI: -0.76 to - 0.17). : Suppression in intermittent exotropia patients could affect the fusional convergence in the dominant eye.
评估主导眼和非主导眼的融合聚散贡献率与抑制深度和外斜视控制的相关性。：横断面前瞻性研究。：使用眼动跟踪系统测量 25 名间歇性外斜视患者（平均年龄 10.8 ± 3.4 岁；范围 6-18 岁）的融合聚散。根据融合时相对于外斜视角度的聚散幅度定义贡献率。评估抑制深度，并使用间歇性外斜视办公室控制评分评估外斜视控制。我们分析了主导眼和非主导眼的贡献率与抑制深度或控制评分之间的相关性。：主导眼的贡献率与双眼抑制深度呈负相关（在注视主导眼时 = -0.85，95%置信区间[CI]：-0.97 至 -0.20；在注视非主导眼时 = -0.91，95%CI：-0.95 至 -0.40）。主导眼的贡献率与 4 米距离的控制评分呈负相关（ = -0.53，95%CI：-0.76 至 -0.17）。：间歇性外斜视患者的抑制可能会影响主导眼的融合聚散。
