Eyeball plays a quite important role in acquiring vision. Vitreous body occupies the largest part in the eyeball and consists of biological, elastic, transparent, gel materials. In the present medical examination, the non-destructive examination method of the vitreous body has not been established. Here we focus on an application of dynamic light scattering to this topic. We try to apply our lab-made apparatus, scanning microscopic light scattering (SMILS), which was specially designed for observing the nanometer-scale network structure in gel materials. Also we try to implement the SMILS technology to a commercial apparatus, nano Partica (Horiba Co., Ltd.), in order to examine the vitreous body. We add several customizations to the nano-Partica. By using both the SMILS and the customized nano Partica, we successfully examined the vitreous bodies from patients and healthy pigs. This work is kindly supported by the doctors in the Hospital of Yamagata University.
