This may be debatable, but many consider our vision as the most important out of the five senses we have. An eye injury is more debilitating compared to the loss of any senses If you are deaf, you can still communicate through sign language. The same thing is with being mute, sign language and lip-reading are possible when you can see. When you do not have a sense of smell, you can still appreciate food and anything that has an odor if you can see it. So it really would be a burden if a brain injury affects your sense of sight. Do you know the common traumatic brain injury eye problems that one can get?
Common Traumatic Brain Injury Eye Problems
Research showed that there is approximately 20% to 40% possibility that a person with a traumatic brain injury like concussion would have a vision problem as well. While some are just temporary, there are other vision impairments that can last a person’s lifetime, depending on the intensity of the injury and the health of the individual.
The common traumatic brain injury eye problems can be grouped into four main categories:
Visual-motor. This is how our eyes are aligned. Problems may include strabismus or crossed eyes.
Visual perception. This is the ability to interpret what our eyes can see. Object discrimination, visual memory, and sequencing may be factors that are affected by this category.
The visual field is for the peripheral and central vision of a patient. Patients may experience hemianopsia (blindness on half of the field of vision, quadranopsia (a quarter of the visual field is lost), and homonymous or bitemporal hemianopsia.
Visual acuity is the sharpness of your sight. This is where nearsightedness or farsightedness are grouped.
Traumatic brain injury eye problems examples
Retinal detachment. This is when the lining at the back of your eye called the retina gets detached by force. Retina serves as a gateway for your nerves to signal the brain about what you see. Severe cases of retinal detachment can lead to blindness.
Vitreous hemorrhage. The vitreous humor is a gel-like substance that helps in letting light to enter the eyes and send directly to the brain. When a traumatic brain injury happens, there are times that the bleeding or the hemorrhage from the blood vessels near your eyes enter the capsule and mix with the vitreous humor. This is a temporary injury that cause blurring of vision and tension headaches most of the time, but some patients need medications to enable them to fight the hemorrhage and prevent it from causing any more problems.
Optic nerve damage. Increased pressure in the skull after a traumatic brain injury can put pressure on the optic nerve and kink it, causing delay in relaying the visual signals of the eye to the brain. This may also cause impingement to the blood circulation to the eyes that may cause severe problems like permanent blindness.
We hope that we have shared some important information that would alert you should you have the unfortunate experience of being involved in an accident that can cause a traumatic brain injury. No matter how simple and mild the symptoms are, these visual problems should not be taken for granted and immediate consultation with a medical professional should be made to prevent further visual, or overall health problems.
