So I had a thing with this as a young kid. It caused burn-like scars on my retina. No symptoms after that or vision changes. Did it alter my brain? I don't think so. I will rage in my car when someone is in the left lane driving slow.
There is so much visual processing machinery in the retina that some neuroscientists describe it as an outpost of the visual cortex. In that sense, scarring your retina might indeed have altered your brain. But not in a way that's related to emotional control.
Your eyes are also an outgrowth of the neural tube.
