Optic nerve transection and tectal removal affect phagocytic activity of the pigment epithelium in goldfish.
The phagocytic ability of the pigment epithelium after optic nerve sectioning and tectal removal was investigated in the goldfish by the method of ingestion of latex beads. 4 days after sectioning, an increase in latex beads was evident which decreased by the end of the first week. Tectal removal also triggered increase intake of latex beads which was presented after 7 days.
