Figure 2: Quantification scale of retinal cell fragments on the ILM. (A) Small (< 1 μm in diameter) and solitarily distributed round cell fragments (arrow) (specimen removed from a patient with persistent macular hole, original magnification: x9,500; scale bar = 1.0 μm); (B) Medium sized (1-2 μm in diameter) round cell fragments (arrow) (specimen removed from a patient with persistent macular hole, original magnification: x4,800; scale bar = 2.0 μm); (C) Large (> 2 μm in diameter) cell fragments derived from nerve fiber bundles and retinal cells, such as cell nucleus (arrowhead) (specimen removed for vitreomacular traction syndrome, original magnification: x4,800; scale bar = 2.0 μm); (D) Entire cell body with cellular nucleus (arrow) and cellular organelles such as mitochondriae, endoplasmatic reticulum and Golgi complexes (arrowhead) (specimen removed for proliferative vitreoretinopathy, original magnification: x9,500; scale bar = 1.0 μm).
