This elegant atlas presents the three-dimensional fine structure of the primate retina and choroid, two component tissues of the primate eye that, although crucial for vision and of complex organization, are less than one millimeter in thickness together. A large number of electron micrographs of striking clarity and detail illustrate the subtle yet significant changes in morphology from cell layer to cell layer as revealed by tangential section. Each plate is accompanied by a concise description of morphological characteristics and their relevance for visual function. Related developmental, biochemical, and physiological aspects, as well as data on the quantitative composition of the retina, are also included. An introductory section summarizes what is currently known about the relationship between structure and function for the human and monkey retina and choroid. This atlas will be an attractive and valuable reference for all eye researchers and ophthalmic practitioners concerned with the anatomical basis of primate vision.
