Objective : Oculomotor nerve palsy is a disorder which causes eyeball movement trouble, diplopia, dizziness and eyelid ptosis. It is caused by aneurysm, mass, trauma, infection and so on. But sometimes we can't establish the cause. We observed 3 cases of idiopathic oculomotor nerve palsy patient treated with hominis placenta pharmacopuncture. Method & Result : We treated three idiopathic oculomotor nerve palsy patients with hominis placenta pharmacopuncture and electroacupuncture. As the result, symptoms of three patients were improved remarkably. Conclusion : In this cases, the hominis placenta pharmacopuncture is effective on idiopathic oculomotor nerve palsy. We need further study about idiopathic oculomotor nerve palsy and hominis placenta pharmacopuncture.
Spherical arrangement of biomimetic polymer photonic structures

Compound eyes in nature present intriguing topics in physiological optics due to their unique optical scheme for imaging. For example, a bee's eye has thousands of integrated photonic units called ommatidia spherically arranged along a curvilinear surface so that each unit points in a different direction. The omni-directionally arranged ommatidium collects incident light with a narrow range of angular acceptance and independently contributes to the capability of wide field-of-view (FOV) detection. Artificial implementation of compound eyes has attracted a great deal of research interest because the wide FOV exhibits a huge potential for medical, industrial, and military applications. So far, imaging with a FOV over 90º has been achieved only with fisheye lenses which rely on bulky and expensive multiple lenses and require stringent alignment. In this talk, we will discuss about the spherical 3D arrangement of the photonic structures of biologically inspired artificial compound eyes in a small form-factor to have and the functional and anatomical similiarity with natural compound eyes.
