Brief Summary:
This prospective observational study aims to understand the effects of different subaxial body positions on choroidal and retinal blood vessel density The main questions it aims to answer are as follows1 How do retinal and choroidal blood vessels adjust and repair after changes in body position2 Is the change of body position related to the factors that cause myopia 3 Are there any differences in the regulation ability of fundus blood vessels in people with different ocular axes under the condition of changes in body position
Detailed Description:
This project will use the wide field swept-source optical coherence tomography angiography combined with data analysis and mining methods to explore the self-adjustment and change mode and mechanism of retinal and choroidal blood vessels in the case of posture changes in an all-round and multi-angle way There would be three kinds of postural changes one is 15 head-up position one is supine position and the other is 15 head-down position Relevant ophthalmological measurements would be performed before and after the postural changes The objective is to discover the three-dimensional change mode of retinal and choroid blood vessels in different postures and compare the differences among people with different lengths of ocular axes and to elucidate the relationship between the mode and ability of retinal and choroidal blood vessels to adjust and repair changes after changes in body position and myopia to provide more ideas and objective basis for the occurrence and development of myopia and lay a foundation for further research It is of great significance to innovate the pathogenesis of myopia deepen the theoretical understanding and guide the prevention and control of myopia
