Figure 1: Retinoblastoma. (a-c) Infant with small macular retinoblastoma (a) with spectral domain optical coherence tomography (SD-OCT) (b and c) showing smooth anterior tumor surface, full-thickness retinal involvement, optically empty cavities, shadowing from calcification, and retinal draping over margins. (d and e) Small retinoblastoma (d) with SD-OCT (e) showing smooth tumor surface and full-thickness retinal involvement. (f and g) Large endophytic retinoblastoma (f) with SD-OCT (g) showing irregular, "frosty" tumor surface with overlying fine vitreous seeds. (h and i) Macular retinoblastoma (h) with SD-OCT (i) showing outer retinal involvement, anterior cavity, and notable inner retinal draping
