Optic Nerve
The optic nerve is a bundle of nerve fibers formed by the convergence of axons from retinal ganglion cells. It exits through the back of the eye and serves as the primary pathway for transmitting visual information from the retina to the brain.

Optic Nerve
In the light-sensitive tissue at the back of the eye, light must pass through several layers of transparent neurons before it reaches the actual light-detecting cells. The long fibers (axons) from one of these neuron layers must then bundle together and exit the eye to carry signals to the brain. What is a direct structural consequence of this 'front-wired' design?

Optic Chiasm
A patient reports a sudden and complete loss of vision in their right eye, while vision in their left eye remains perfectly normal. An examination confirms that the structures within the right eyeball itself are healthy and undamaged. Given this information, where is the most likely location of the damage causing this specific pattern of vision loss?
