Figure 1

Spectral-domain optical coherence tomographic (SD-OCT) image of a retina showing how the outer retinal thickness and PROS length were measured. The outer retinal thickness was measured from the external limiting membrane (ELM) to the outer border of the highly reflective retinal pigment epithelium (RPE) line. The photoreceptor outer segment (PROS) length was measured from the ellipsoid zone (EZ) to the RPE line.
