The Fine Structure of Retina Studied with Electron Microscope

The structure of pigment epithelium, together with its functional relationship with visual cells, was studied intensely by light microscopists (for references, see 1, 2 or 3). There were also several reports of electron microscopic studies of the structure4–7). They concerned, however, chiefly with parts of the structure, e.g. isolated fuscin granules, but not with its overall feature. It seemed to the authors therefore to be worthwhile to study its fine structure with the electron microscope in relation to studies reported hitherto.
