Fig. 8. (A) Tangential section through the pigment layer (PL) and posterior scleral stroma (PSS) in the light-adapted condition. The pigment cells have a sheet-like appearance. Scale bar, 5 µm. (B) Transverse section through a pigment reservoir cell in the dark-adapted condition. The cell contains granular material (GM) and vacuoles (V). Scale bar, 0.5 µm. (C) Transverse section through two pigment processes in the central cornea during light-adaptation. The cytoplasm contains granular material (GM) as well as vacuoles (V) of different sizes containing material with varying osmophilic affinity. Microtubules (MT) are arranged parallel to each other and the cell membrane. These may be involved in the transport of the pigment from the pigment reservoir into the pigment cell processes. Scale bar, 0.5 µm.
