In the course of an investigation on breeding, management, health and economic problems in seven Highland Cattle farms, two castrated (male) full sibs were detected showing divergent unilateral strabismus (DUS). The reason being found for this eye-defect was a displacement of the M. rectus lateralis by 40 degrees to ventral. Besides DUS, both full sibs were affected by crop ears. It seems probable that DUS is an inborn defect, but the pedigree was not so informative that conclusions on the inheritance of DUS could be drawn.
在对七个高地牛养殖场的繁殖、管理、健康和经济问题进行调查的过程中，发现了两头去势（雄性）全同胞表现出不同的单侧斜视（DUS）。发现这种眼部缺陷的原因是外直肌向腹侧移位40度。除了DUS，这两头全同胞还患有卷耳症。DUS似乎是一种先天性缺陷，但系谱信息不足，无法得出关于DUS遗传的结论。
