The RGCs connecting to the red and green cones are midget RGCs. This is due to our having three different kinds of color sensitive cone cells: red cones, green cones, and blue cones. Human beings can see three primary colors: red, green, and blue. The RGCs form multiple functional pathways within the optic nerve to mediate the visual signal

having a long axon that extends into the brain via the optic chiasm and the optic tract.

possessing a cell body (soma) at the inner surface of the retina.

They all share the defining properties of: Those visual transmitting RGCs are the neuronal cells. In the retinal tissues of the eye, more than 23 types of RGCs vary significantly in terms of their morphology, connections, and responses to visual stimulation. In the brain, the optic nerve transmits vision signals to the lateral geniculate nucleus (LGN), where visual information is relayed to the visual cortex of the brain that converts the image impulses into objects that we see. In the human eye, the optic nerve receives light signals from about 125 million photoreceptor cells (known as rods and cones) via two intermediate neuron types, bipolar and amacrine cells.

The optic nerve is mainly composed of retinal ganglion cell (RGC) axons.

Cerebral amyloid angiopathy: This is the build-up of proteins within the walls of arteries in the brain that can cause them to weaken, leak, and rupture.Arteriovenous malformation: These are defects in the connection between arteries and veins that cause them to weaken, leak, and sometimes burst.Brain tumor: Cancerous and non-cancerous tumors can cause bleeding by placing pressure on adjacent blood vessels as they grow, gradually weakening them and causing them to burst.The ensuing pressure can sometimes cause the vessel to burst, causing bleeding referred to as hemorrhagic conversion. Hemorrhagic conversion: An ischemic stroke is a type of stroke caused by the obstruction of a blood vessel in the brain.Even heavy lifting or straining can cause pressure within the brain to rise enough to trigger an eruption. Hypertension (high blood pressure) is the most common cause of a rupture. Ruptured aneurysm: An aneurysm is the bulging of an artery that can cause it to burst.Head trauma: A head injury caused by a fall, vehicle accident, or any other blow to the head usually causes bleeding between the skull and surrounding membranes, resulting in an extradural, subdural, or subarachnoid hemorrhage.
