Characteristics of the study participants.
Version 1PurposeTo investigate variation in reflectivity of choroidal layers in normal eyes.MethodsFrom the swept-source optical coherence tomography database, we retrospectively included eyes with a normal fundus. Choroidal reflectivity was measured on the horizontal and vertical B-scan optical coherence tomography images. The optical barrier of the choroid was defined as the first hill in the middle of the reflectance graph from the retinal pigment epithelium-Bruch’s membrane complex to the chorioscler
