Figure 2. Patient #9. Blue fundus autofluorescence (FAF) and spectral-domain optical coherence tomography (SD-OCT) reveal the left eye affected with previtelliform lesion at both study entry and last follow-up visit (50 months later). Blue FAF frames show no increased macular autofluorescence at either study entry (top left panel) or the last follow-up visit (bottom left panel). SD-OCT scans show a slight thickening of the hyperreflective band located between the hyperreflective photoreceptor inner segment (IS) ellipsoid portion (ellipsoid zone, EZ) and the hyperreflective retinal pigment epithelium (RPE)/Bruch’s membrane complex at study entry (top right panel) and the last follow-up visit (bottom right panel).
