Cortical visual impairment is caused by which of the following?

Explanation:
Cortical visual impairment results from problems in the brain's processing of visual information, not from the eyes themselves. Even when the eyes and optic nerves are functioning normally, damage or dysfunction in the visual cortex or related brain pathways can disrupt how visual signals are interpreted. This is why the cause is described as brain issues in CVI. It can arise from perinatal brain injury, stroke, hypoxia, trauma, or other neurological conditions, and vision can range from mild to profound—not necessarily complete blindness. Other options point to issues with the eye itself or non-visual sources, which do not explain CVI.
