: Aniseikonia, an appreciation of image size differences between the eyes, can produce symptoms in patients, ranging from headaches to loss of fusion. The purpose of this research was to take a 21st century look at aniseikonia. : Kellogg Eye Center patient records were evaluated for measurable aniseikonia in patients tested with the Aniseikonia Helper, a tablet-based application. Anaglyph slides for the synoptophore were developed to test the limits of induced aniseikonia on stereopsis and fusion. A survey was developed to determine how frequently members of the American Association of Certified Orthoptists (AACO) examine and treat patients with aniseikonia.: The prevalence of measurable aniseikonia in this cohort was 7.8%. Moderate amounts of induced aniseikonia, 4% induced image size disparity, disrupt fusion and can cause a loss of stereopsis. Eighty percent of responding AACO members see patients with aniseikonia and among those, 25% see them on a monthly basis. Treatment options, other than wearing contact lenses, are limited to occlusion or fogging techniques. : Aniseikonia remains a frequent complaint among patients. The ophthalmologic community needs to use the best methods for measuring aniseikonia and to develop better methods for treating aniseikonia.
双眼像不等，即双眼对图像大小差异的感知，会使患者出现从头痛到融合功能丧失等症状。本研究的目的是从21世纪的视角审视双眼像不等。对凯洛格眼科中心的患者记录进行评估，以确定使用基于平板电脑的应用程序“双眼像不等辅助工具”进行测试的患者中可测量的双眼像不等情况。为同视机制作了互补色立体视觉图片，以测试诱发双眼像不等对立体视觉和融合功能的影响极限。开展了一项调查，以确定美国认证斜视矫正师协会（AACO）成员检查和治疗双眼像不等患者的频率。该队列中可测量的双眼像不等患病率为7.8%。中等程度的诱发双眼像不等，即诱发4%的图像大小差异，会破坏融合功能并导致立体视觉丧失。80%做出回应的AACO成员会诊治双眼像不等患者，其中25%的成员每月都会诊治此类患者。除佩戴隐形眼镜外，治疗方法仅限于遮盖或雾视技术。双眼像不等仍是患者常见症状。眼科界需要采用最佳方法测量双眼像不等，并开发更好的治疗方法。
