Brain tissue is connected with the eyes through the blood supply, muscles and nerves. Because of this close connection, head injuries can often cause visual dysfunctions. Unfortunately, visual problems from brain injuries are often hidden and dismissed because the sufferer’s complaints can seem vague and inconsistent
Additionally, vision is the most important sensory system. A large portion of the brain is reserved for processing what arrives through the eyes (ventral stream processing). Other visual portions of the brain help guide physical action (dorsal stream processing). Whether a brain injury is due to trauma, stroke, or whiplash, it is still classified as a brain injury and can affect vision in a number of ways.
The following are some types of brain injuries that can impair vision:
- Closed Head Injury
Some of the common visual symptoms from brain injuries are:
- Blurry vision
- light sensitivity
- reading problems
- attention and concentration difficiculties
- double vision
- achy eyes
- headaches associated with visual tasks
- loss of side vision or hemifield loss
Treatment for vision problems due to brain injuries can involve glasses, tints, filters, prisms, other optical devices and vision therapy.
