Investigation of the Regulation of Retinal and Choroidal Blood Vessels in Various AL Based on WF SS-OCTA Detection With Changes in Body Position

60 participantsStarted 2024-10-01

Plain-language 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 follows:1) How do retinal and choroidal blood vessels adjust and repair after changes in body position?2) 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?
