In recent years, retinal research has benefited from major advances in optical imaging
approaches. Investigations of the structural and functional organization of the vertebrate
retina using live preparations have been facilitated by improvements in cell labeling
methods, and by microscopy techniques that permit high-resolution of cells in vitro and in
vivo. In particular, the generation of transgenic animals with fluorescently labeled retinal
cells has permitted real-time visualization of cell generation, migration, differentiation and …
