Morphological Study of Color Doppler Ultrasound Imaging to Observe the Effect of Ocular Fundus Surgery

High myopia continues to progress and the eye axis continues to grow, resulting in mechanical dilatation of the eyeball wall, and with the increase of age, resulting in a variety of myopic fundus pathological changes. Considering that in the late stage of fundus disease, patients can obviously feel the impact of the disease on vision, and ophthalmologists are needed for direct diagnosis, intervention and treatment. The impact of early lesions on vision is relatively weak, and patients can not detect the emergence of these lesions in time, which can only be found by fundus survey. Therefore, the automatic detection of early lesions of fundus disease (especially microaneurysms) is not only of great significance for early diagnosis and early treatment of fundus disease, but also a good reference for the detection of other fundus diseases. In this paper, color ultrasound can effectively analyze the origin of fundus diseases. The results showed that with the changes of age, eye axis and posterior sclera shape in high myopia, the area and range of myopic arc and choroidal atrophy arc expanded, the thickness of nerve fiber and choroid became thinner, and the fovea of macula mainly shifted vertically. In addition, it was also found that myopic arc, choroidal atrophic arc area, retinal thickness, nerve fiber thickness, choroidal thickness, vertical distance from macular fovea to optic disc center were correlated with age and eye axis.
