Figure 1.

Enhanced depth imaging OCT was used to measure the thicknesses of the choroid and retina in the subfoveal region and at a distance of 3000 µm nasally and temporally to the foveola on horizontal scans of right eyes were measured. Choroidal thickness (line) was defined as the vertical distance from the RPE to the inner surface of the sclera; retinal thickness was defined as the distance from the internal limiting membrane to the interface between photoreceptor outer segments and the RPE.
