The Research Of The Preliminary Application Of The Retina Adaptive Optical Imaging System In Clinical Ophthalmology

The retina is the accuratest and the most complex tissue of the eyes, in the earlyperiod it is difficult to discover the pathological changes of each layer of retina and thesecondary lesions which caused by other diseases, so it is irreversible to damage thevisual sense and even cause the eyes blind. the human eye is nonideal dioptric system,which exists low and high order difference, these existing differences will influencepeople’s vision. The retina adaptive optical imaging system can use adaptivetechnology to correct the human’s poor eye and get the high resolution image of retinalcones. Through the extraction and contrast of characteristics of the retinal image, thedoctor can promptly find the early lesions of the patients in the existing fundus todetermine course, and then help the doctor to achieve the early diagnosis of thisdisease.So far, on the retina of the adaptive optics high resolution imaging technology athome and abroad, most of the research is still in the experimental stage, there is noclinical instruments and equipment. Chengdu Keaoda photoelectric technology limitedson, who designed the research of the adaptive optical imaging system that is firstclinical equipment used in the international medical world, according to therequirements of experiments, this paper studies the retina adaptive optical imagingsystems measure normal eye retina cone cell density in disease diagnosis and theapplication value of the preliminary researchThis article first introduces the necessity of study of the retinal adaptive opticalimaging system, and analyses the application of this system’s feasibility which was usedin the clinical ophthalmology from the composition and working principle of thissystem in the eye of the clinical application, And then, through the introduction of theeye and the structure of the retina, which will lay the visual image of the theoreticalbasis for our next retinal cones, and then deal with the retinal cones image, finallyestablished the contrast stretching and enhancement of diffusion,edge extraction andtensile diffusion sharpening, and the open computing algorithm combined with such asthe treatment method, the processed image whose feature information is moreprominent, which laid a foundation for cell number statistics. In the clinical trials,mainly from two aspects of the experiment, on the one hand, on the the preliminaryresearch of the adaptive optical imaging system for normal cone cell imaging, throughprocessing the effective retinal image to get the deviation ratio for the many different cone cell image density and diameter statistics. On the other hand, it is the retinaadaptive optical imaging system in the research on the application of eye diseasediagnosis. Through the use of the retina adaptive optical imaging system for people withcertain the fundus disease detection and get the patient’s retinal cones image, then do acomparative analysis of normal people, retinal cones are significantly different betweenthe images of them. in short, It shows that the retina adaptive optical imaging systemcan be used as auxiliary methods for some eye disease detection.This article give the pilot study on the retina adaptive optical imaging system ineye clinical application, which lay a foundation for the improvement, the specificapplication of the system and also lay a foundation for this product eventually applied toclinical。...
