Iris pigment epithelium, SEM
Iris pigment epithelium. Coloured scanning electron micrograph (SEM) of a section through the iris of an eye, showing the iris pigment epithelium (IPE). The IPE is a layer of cuboidal cells (pink) that lies behind the iris. Each cell contains numerous large melanosomes (blue), which contain the pigment melanin. The concentration of this melanin is one of the factors that determine the colour of a persons eye. Magnification: x3, 300 when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate beauty of the iris pigment epithelium (IPE) found in our eyes. In this coloured scanning electron micrograph, we are granted a glimpse into the hidden world of biology and tissue that contributes to our vision. The IPE, depicted here as a layer of delicate pink cuboidal cells, resides behind the iris and plays a crucial role in determining eye color. Each cell within this layer contains numerous large melanosomes, represented by their striking blue hue. These melanosomes house melanin pigment, which is responsible for giving color to our eyes. With a magnification of x3,300 when printed at 10 centimeters wide, this image allows us to appreciate the astonishing level of detail present in even the smallest components of our bodies. It serves as a reminder that there is so much more than meets the naked eye when it comes to understanding human anatomy and physiology. Photographer Steve Gschmeissner skillfully captures both artistry and scientific precision with his false-colored scanning electron micrograph. This mesmerizing composition not only appeals to those interested in ophthalmology or ocular health but also provides an opportunity for all viewers to marvel at nature's remarkable design within ourselves.
