Research Abstract |
In this study, in vivo choroidal changes that had not been well elucidated were investigated. As a result, the choroidal thickness in normal eyes was found to be affected by axial length, age and other parameters. The shapes of large choroidal veins were found to be rounder in eyes with thicker choroid. In some highly myopic normal adult eyes, axial length was found to increase significantly and choroidal thinning and progression of posterior staphyloma also occurred at the same time. This study revealed basic knowledge of normal choroid and changes in eyes with chorio-retinal diseases. Choroid was found to be dynamic tissue that may change according to the surrounding environment.
