The orbital apertures of Primates are among the most convergent (i.e., facing in the same direction) among mammals. It is often assumed that orbit convergence is associated with binocular visual field overlap and stereoscopic depth perception in primates. Likewise, it is also assumed that orbit orientation reflects the shape of the visual field across mammals. To date, however, no study has demonstrated that orbit and visual field orientation are correlated, much less comparable, across mammals. In this study, data on orbit convergence were collected for a representative sample of mammals for which data on the extent of the visual field are available. Both standard and phylogenetically controlled comparisons were made. The results demonstrate that orbit convergence and binocular visual field overlap are significantly correlated and display a linear relationship. Based on orbit convergence, Primates as a group have the largest binocular visual fields among mammals.
灵长类动物的眼眶孔在哺乳动物中是最趋同的（即朝同一方向）。人们通常认为眼眶趋同与灵长类动物的双眼视野重叠和立体深度感知有关。同样，人们也认为眼眶方向反映了整个哺乳动物的视野形状。然而，迄今为止，尚无研究表明在整个哺乳动物中眼眶和视野方向是相关的，更不用说具有可比性了。在本研究中，收集了有视野范围数据的代表性哺乳动物样本的眼眶趋同数据。进行了标准比较和系统发育控制比较。结果表明，眼眶趋同与双眼视野重叠显著相关，并呈现线性关系。基于眼眶趋同，灵长类动物作为一个群体在哺乳动物中具有最大的双眼视野。
