Portable clinical EOG instrument system

It is very important to study the EOG system in eye movement for both clinicians and basic scientists due to the abundant neuropathological information. However, the present commercial stimulation instrument only provides very few and fixed patterns. Therefore, techniques of computer animation, data acquisition, data analysis and database management are applied to implement an intelligent instrument that can stimulate and diagnose EOG system with patterns freely set by the doctors or the researchers, so that vision and nerve system illnesses can be studied efficiently. Instead of the expensive and huge commercial stimulation instruments in the present market, in this paper a personal computer is used due to its cheapness, popularity, multifunction and fast speed. A lot of interesting stimulation patterns can easily be created in shape, time sequence, and color under Windows 95. It is hoped that this invention can contribute to clinical diagnosis and basic medical science research for EOG
