Which visual impairment is caused by brain injury?

Explanation:
Visual processing problems caused by brain injury are called cortical visual impairment. It happens when damage affects the brain’s visual pathways or processing centers, so the eyes may be healthy but the brain struggles to interpret what is seen. This differs from eye-based issues like glaucoma, which involves optic nerve damage often related to pressure inside the eye, or macular degeneration, which damages the retina’s central area. The vitreous humor is the gel inside the eye, and problems there affect vision differently and are not about brain processing. So the brain-injury–related visual impairment is cortical visual impairment.
