Yes, it would cause that. Eye and vision problems are fairly common after a brain injury. Some vision problems like retinal detachment can be caused by trauma to the eye. As we all known, the retina is a thin layer of tissue lining the inside of the back of the eye. It has the functionality of turning images to enter the eye into signals, which goes to the brain through the optic nerve. People who have a head injury could bleed into the retina to cause retinal detachment in both eyes. In a retinal detachment, the retina comes loose that is an issue to potentially cause permanent blindness.
Yes. Head trauma is possible to cause retinal detachment. In fact, the trauma causing a detachment is vague. For example, if you get a blow by a baseball bat or other balls, it will cause retina to detach. I heard that retinal detachment are often occurs in movement such as whirling of rotating and some other sports activities.
