Abstract
Retinopetal projections from isthmic and caudal mesencephalic regions were studied in a number of poikilothermic vertebrates. The tested animals were elasmobranchs, bony fishes, amphibians, and reptiles. Isthmo-optic projections were absent in elasmobranchs, sturgeons, most teleosts, all anuran and urodel amphibians, and in anolis lizards. Tegmental projections to the retina were found in a few fishes and in most reptiles. Interspecific variations regarding three morphological parameters were as follows: (i) isthmic projections to the contralateral eye originate from one or from two distinct nuclei; (ii) major interspecific differences exist regarding numbers and aggregation densities of cells in the nuclei of origin; (iii) the percentage of retinopetal fibres that innervate the ipsilateral retina varies significantly between species.
