Transmission electron microscopy photomicrograph of inner nuclear layer of retina in paraneoplastic vitelliform retinopathy. The degenerated cells are at various stages of disintegration and most of their cytoplasmic organelles are absent. The mitochondria were degenerate and only their outer membranes were visible (arrows, original magnification, ×8000, scale bar, 2 μm). There were numerous lysosomal and autophagous bodies (Figure 4 inset, original magnification, ×25000) within the cells.
