Aqueous Levels of Pigment Epithelium-Derived Factor and Macular Choroidal Thickness in High Myopia

Figure 1

Optical coherence tomography (OCT) images using enhanced-depth imaging. The choroidal thickness (red line) is defined as the vertical from the outer surface of the hyperreflective line ascribed to the retinal pigment epithelium (RPE) to the hyperreflective line of the inner sclera border (a). Representative scan of a control individual (b). Representative scan of an individual with high myopia without choroidal neovascularization (CNV); note that the choroid is thinner than in the control but thicker than in high myopia with CNV (c). Representative scan of an individual with high myopia with CNV; note that the choroid is thinner than that of control or high myopia without CNV.
