Summary

In order to provide reference for clinical application, the normal values of retinal blood flow parameters in Chinese healthy children were measured by oct-angiography. Meanwhile, the repeatability and consistency of retinal blood flow parameters measured by oct-angiography in children were further analyzed, and the correlation of retinal blood flow parameters with eye axis, choroidal thickness, age and diopter was analyzed, so as to provide basis for clinical diagnosis of children's ophthalmopathy. Objective to study the effect of short-term optical defocusing on retinal blood flow parameters, and analyze the correlation between the changes of posterior segment parameters before and after short-term optical defocusing, so as to provide the basis for the possible compensation mechanism of posterior segment optical defocusing, and further understand the possible physiological mechanism of myopia.
