Programming Of Stereopsis Test Software And The Discussion Of Its Practical Value

This thesis mainly discuss the practical value of the stereopsis test software in the ophthalmic clinical test of stereopsis, compare the difference between the traditional TNO method and our software, measure the normal value of distant and near stereo acuity of health people .analyze the relation between the age and stereopsis, analyze the relation between the distance and stereopsis, test the near stereopsis development of young children with ophthalmic disease, test the influence on stereoacuity of the size of random dot.This article include three part, in the first part, we clarify the principle of the stereopsis developing, including the physiological element of stereopsis, its developing process and classification. And point out that binocular parallax is the necessary element of stereopsis. Review the equipment or method that have been or deing used in the stereopsis test, and the suitable people to use them, analyze all kind of problem or disadvantage of them. The second part is programming of the software. This software contain five module, they are whole storeopsis module, local storeopsis module, dynamic random dot module, module of communication with ophthalmic electric equipment, demonstration module. The third part is clinical test, data analysis and statistics. The experiment object include normal people and patient, the normal people were divided into three group, the people' s age were between 10 and 14 in first group , between 22 and 29 in second group , between 30 and 42 in third group , and the total was 63. The patient total up to 70, and their age were between 4 and 13.In the course of research, the article experienced software programming, clinical practice and modification again and again, data analysis. Through the clinical practice and data analysis, it was proved that this software has great practical value.
