The viscoelastic properties of the vitreous body from bovine and porcine eyes were determined by microrheometry. Each vitreous sample was sectioned into anterior, central and posterior segments. The rheological properties of each species and region were compared with each other and with the viscoelastic properties of human vitreous reported earlier. The results showed significant variations among species, as well as between regions in all species. All regions of human vitreous have significantly different rheological properties from those of the cow, and from the anterior and posterior regions of the pig; however, the viscoelastic behavior of the central porcine region closely resembles that of the human. In comparing the three species, the major differences found are in those parameters characterizing "viscous" or dissipative properties; values of "elastic" or energy storage properties were similar.
通过微观流变学测定了牛眼和猪眼玻璃体的粘弹性特性。每个玻璃体样本被切成前部、中部和后部片段。比较了每个物种和区域的流变学特性，并与之前报道的人类玻璃体的粘弹性特性进行了比较。结果表明，物种之间以及所有物种的不同区域之间都存在显著差异。人类玻璃体的所有区域与牛玻璃体以及猪玻璃体的前部和后部区域的流变学特性都有显著差异；然而，猪玻璃体中部区域的粘弹性行为与人类的非常相似。在比较这三个物种时，发现的主要差异在于表征“粘性”或耗散特性的参数；“弹性”或能量存储特性的值相似。
