These are retinal ganglion cells that transmit information to the brain:

"In work that brings researchers closer to the goal of precision medicine approaches to treating glaucoma and other neurodegenerative vision diseases, a new IUPUI study has, for the first time, been able to identify a wide variety of previously unknown cell subtypes in the human eye. The cells—called retinal ganglion cells, also known as RGCs—are the neurons that take visual information from the eye to the brain for processing and interpretation, which is how we see things.

"'Although RGCs have been extensively studied in the past, they are not all the same. There are more than 30 different subtypes of these cells," said study senior author Jason Meyer, associate professor of biology in the School of Science at IUPUI and a primary investigator with the Stark Neurosciences Research Institute at the Indiana University School of Medicine. "Each of these subtypes is thought to have very different functions, and they respond differently in glaucoma and other diseases that affect RGCs. Some of these cell subtypes are more susceptible to damage than others.'"

Comment: The upside down and backwards human retina has been shown to have excellent oxygen delivery and adapts beautifully to every lighting situation. These neurons are in a way an extension of the brain to provide the most exact information possible. This reeks of design.
