Introduction The retina as an organ of perception of light, colour,
shape and movement has been the subject of numerous and intensive
light- and electron-microscopical investigations. To date the
interest in these has largely been concentrated on the structure of
the ma ture retina and the genesis of its cellular elements. The
first exhaustive observations on the development of the retina in
vertebrates were made by Babuchin (1863). Using the retinae of
chicken embryos, he showed that Millier's radial fibres and the
ganglion cells are the first to develop, while the receptor
segments are the last. Subsequently, the early differentiation of
Millier's radial fibres was often reaffirmed (Cajal, 1893; Meller,
1968; Bhattacharjee and Sanyal, 1975; and others). Furthermore,
Babuchin had already indicated that the structural development in
the area of the posterior pole is very rapid compared with those
regions of the retina which are situated more peripherally. Today,
when comparing results of electron-mi croscopical investigations,
this fact is of particular importance, since in each case only very
limited areas of the retina can be examined. Schultze (1867a, b)
pointed out the uniformity of origin and the general classifica
tion of light-perceiving elements into inner and outer segments,
thus contesting the hitherto generally held opinion that these
structures, like the pigment epithelium, ori of the eye cup. In
1881 Ogneff discovered the analogous ginate from the outer leaf
mode of formation in birds and mammals."
