Figure 3: Retinal pigment epithelial (RPE) tumors. (a and b) Congenital hypertrophy of the retinal pigment epithelium (a) with enhanced depth imaging optical coherence tomography (EDI-OCT) (b) showing abrupt photoreceptor loss over the flat lesion, subretinal cleft, and transmission of light through lacunae. (c and d) Combined hamartoma of the retina and RPE (c) with EDI-OCT (d) showing thickened retina with disorganization and "folded" appearance with overlying dense epiretinal membrane. (e and f) Congenital simple hamartoma of the RPE (e) with EDI-OCT (f) showing an abrupt dense inner retinal mass with absolute shadowing and normal choroidal thickness. (g-i) RPE adenoma (g) with EDI-OCT showing remote cystoid macular edema (h) and irregular surface, tumor nodule, and deep shadowing (i)
