摘要

For the first time, the morphological properties of organelles with screening pigment in the supporting cells of the non-optic part and the peripheral and central region of the optic part of the retina of the camera-like eye of the gastropod Helix pomatia were studied using light and transmission electron microscopy: way of arranging; shape; location; way of packaging; structure. A comparative visual assessment of the number of organelles with a screening pigment having a different way of arranging and the number of organelles with a screening pigment having a different shape for each way of arranging was performed, and the size of organelles with a screening pigment in the supporting cells of the non-optic part and the peripheral and central region of the optic part of the retina of the camera-like eye of H. pomatia was measured. It was shown that organelles with screening pigment in the supporting cells of the non-optic part and the peripheral and central region of the optic part of the retina of the camera-like eye of H. pomatia have more similarities than differences in morphological properties, number, and size.
