| Abstract(in English) | This study aims to develop an objective measurement of the senile dementia. A pocketlight is used as the light-stimuli, a CCD camera used to see the changes of pupils, while the pictures are copied to computer to measure the pulil's size. The differences on light reflex between the normal subjects and the senile dementia is found out by this system. The senile demented patients show smaller changes (p<0.01) and longer delay times(p<0.05) than the normal elders, when their pupils are lightened by pocket-light. The results may be applied to the new objective method to evaluate the senile dementia objectively. |
