The Development Of Amblyopia Therapy Instrument

Amblyopia is caused by some reasons so that patients have poor eyesight beginning from childhood, and their eyes looks the same as ordinary people, but their eyesight can't reach to 0.9 whatever glasses they wear. At present there is more than 300 million Children in China, and it is estimated that the number of children who have poor eyesight at 10 million. The person who more young will be more effectiver in healing amblyopia, adults will have no effectiveness in the treatment. At the same time, the cure also is an enduring process, it needed parents and children both to take part in the activities.In this paper we mainly introduce a new method to cure amblyopia and this method haven't been reported in China. This method is different from the traditional therapy methods, such as the mask,eye stimulation,laterimage,suppression,red rubber film,drug and the helium_neon laser therapy.In this paper, I will from two fields to introduce my work,one is the hardware,another is the software. The hardware of this instrument composed of controlment uint,power uint,function uint and time uint. In this part,I give out a detailed illustration about the laser,flash,laterimage and multispectrum therapy ways how to realize in the circuit, at last I also give out some technical parameter about the Light-emitting diode(LED) and the therapy instrument.At the software field, I adopted Keil uVision platform and C language to compile programe. According to the technical parameter and functional demand, the software field include main function, selection function, interrupt function and work function etc module. At last,through the debug I found that the programe can work normal by the command.Finally I did a clinical experimental, through the experiments , I can have a conclusion that this amblyopia therapy instrument is safe,reliable,effective and have a better clinical applicable value.
