[In situ hybridization on tissue section: a new method for studying the amacrine cells of the retina and the centers of the visual system].

In situ hybridization of nucleic acid probes, encoding the key enzymes of the synthesis of neurotransmitters, with sections of retina is a new method giving complementary informations to the data obtained by immunocytochemistry and autoradiography. It will allow a better characterization of amacrin cells, whatever might be their type, and a refined understanding of their function. It is an accurate tool to investigate the mechanisms of retinal degenerations and spontaneous or experimental microphtalmia.
