Major in Rehabilitation Sciences
Field of Visual Sciences

Overview

This field is designed not only for orthoptists but also for students who desire to become experts in the area of visual sciences after completing their basic studies. Toward that end, the teaching will be focused on both the fundamental area of visual sciences and the clinical area of ophthalmology from multiple perspectives. Therefore, our goal is to raise competent international-minded QOL supporters who can respond flexibly to the needs of society that concern our specialty and who can engage in team medicine and team care.

Characteristics

Invention of new methods of inspection in the field of ophthalmology
The orthoptist is an expert in the inspection of visual performance. However, many of the methods of inspection currently used are often difficult to apply to the elderly and small children. This is because these methods require subjective responses from these people and these responses are often not adequate or accurate for effective diagnosis. Therefore, the clinical site needs an inspection method that can evaluate visual performance efficiently and accurately in a short time. Against this backdrop, the field of visual sciences plans to establish a principle based on the characteristics of visual performance and to develop a new method of visual performance inspection.
Development of new testing equipment in the fields of visual engineering and optics
In the field of ophthalmology, new testing devices have been developed one after another, including the optical coherence tomography. For those in the field of engineering, the development of testing equipment is an attractive theme. But it is also difficult for them to examine the clinical content. For this reason the field of visual sciences can provide clinical guidance for teachers specialized in engineering and optics as well as ophthalmologists and orthoptists.
Study of the brain function connected with the sense of vision
The sense of vision sends a stimulus first into the eye and then onto the brain. Then the brain turns it into the information that creates purposeful actions of the eyeball and other connected organs. This means that the study of the visual sense concentrates not only on the eyeball but also on the entire brain function. Therefore, the field of visual sciences uses electrophysiological and psychophysical methods in the study of the functional role of the brain and the sense of vision.
