目的：建立一种利用双眼竞争和视力计定量检测眼优势的新方法，并研究白内障患者手术前后眼优势的大小。研究对象：日本神奈川市相模原市北里大学医学院医院眼科诊所。方法：测量60名健康志愿者(研究1)和10例白内障患者(研究2)在双眼竞争中优势和非优势眼靶点的唯一可见时间。使用2个视网膜计将竞争靶点直接呈现在每只眼的视网膜上。结果：在研究1中，根据优势眼和非优势眼的专有可见性总时长的差异，对眼优势的大小进行了4个等级的量化评估。在研究2中，无论屈光和白内障情况如何，都可以评估所有白内障患者的眼优势程度。术前、术后眼球优势程度呈显著正相关(简单回归，P
PURPOSE: To develop a new method using binocular rivalry and retinometers to quantitatively examine ocular dominance and to investigate the magnitude of ocular dominance in cataract patients preoperatively and postoperatively.SETTING: Eye Clinic, Kitasato University School of Medicine Hospital, Sagamihara, Kanagawa, Japan.METHODS: The duration of exclusive visibility of the dominant and nondominant eye target in binocular rivalry were measured in 60 healthy volunteers (study 1) and preoperatively and postoperatively in 10 cataract patients (study 2). Rivalry targets were presented directly to the retina of each eye using 2 retinometers. Subjects reported the exclusive visibility of 1 eye target, and the total duration of exclusive visibility for each eye in dominant and nondominant eye trials was evaluated.RESULTS: In study 1, the magnitude of ocular dominance was quantitatively assessed with 4 grades based on differences in total duration of exclusive visibility between dominant and nondominant eyes. In study 2, magnitude of ocular dominance could be evaluated in all cataract patients regardless of refractive and cataract conditions. Magnitude of ocular dominance displayed significant correlations between preoperative and postoperative conditions (simple regression, P
