Macular Thickness, Foveal Volume, and Choroidal Thickness in Amblyopic Eyes and Their Relationships to the Treatment Outcome

Figure 1

Measurements of the macular and choroidal thicknesses. (a) Macular retinal thickness was measured in three concentric rings, with the central ring corresponding to the fovea (1 mm diameter), the middle ring corresponding to the parafovea (3 mm diameter), and the outer ring corresponding to the perifovea (5 mm diameter). (b, c) The yellow lines indicate the locations of the 1000 μm intervals. The distance between the outer border of the retinal pigment epithelium (red dash line) and the hyperrefractive line behind the large vessel layers of the choroid (blue dash line) was defined as choroidal thickness (white arrow).
