TL;DR

Calcium and barium are found in melanin granules of toad retinal pigment epithelial cells and choroidal melanocytes and this suggests that barium may not serve a major role in the normal processes of dark adaptation in vertebrate photoreceptors.

Abstract

Calcium and barium are found in melanin granules of toad retinal pigment epithelial cells and choroidal melanocytes. Calcium, but not barium, was found in photoreceptor outer segments and this suggests that barium may not serve a major role in the normal processes of dark adaptation in vertebrate photoreceptors.
