Can you tell if you have a concussion by your eyes?

Vision or eye disturbances, such as pupils that are bigger than normal (dilated pupils) or pupils of unequal sizes. Ringing in the ears that doesn’t go away. Weakness in the arms or legs. Appearing very pale for longer than an hour.

Can a concussion aggravate MS?

Here’s what they found: Those who had suffered a single concussion between the ages of 10 and 20 had a 22% higher rate of MS than those who had never had a concussion. The rate of MS was more than doubled for those who had experienced more than one concussion.

Why do doctors look at eyes for concussion?

Your eyes are an extension of your brain; vision alone accounts for over 55% of the brain’s pathways. Your eyes are significantly impacted by a traumatic brain injury such as a concussion and are critical to diagnosing defects in brain activity following a concussion.

How do eyes react when you have a concussion?

Blurry or double vision (diplopia) are a common complaint after a concussion and may result from damage to the muscles and/or nerves around the eye. This can stem from what is known as convergence insufficiency; in effect, the alignment of the eyes diverge when trying to focus on nearby objects.

How do they test your eyes for a concussion?

After more serious head injuries are excluded, a diagnosis of concussion can be made. Medical professionals have long used the pupillary light reflex—usually in the form of a penlight test where they shine a light into a patient’s eyes—to assess severe forms of brain injury.

Is sclerosis scarring?

Sclerosis means scarring, and people with MS develop multiple areas of scar tissue in response to the nerve damage. Depending on where the damage occurs, symptoms may include problems with muscle control, balance, vision, or speech.

Can trauma trigger MS symptoms?

If trauma plays a role, it might do so by initiating the aetiological processes that lead to MS or by precipitating the clinical onset of latent disease. One mechanism hypothesised as a causal pathway between injury and MS is through a breakdown of the blood–brain barrier.

Do eyes dilate with concussion?

Dilated pupils are a sign of concussion. Our pupils can become dilated when the autonomic nervous systems sympathetic branch is stimulated and the fight or flight response is triggered. This can happen when the body is under stress due to excitement, nervousness or anxiety.

Should I get my eyes checked after a concussion?

Fortunately, optometrists are uniquely qualified to diagnose and treat visual aberrations related to TBIs and concussions. If you or a family member has sustained a concussion, we strongly urge you to get your eyes examined as soon as possible.

Can a concussion damage your eyes?

Even mild concussions can affect vision and cause visual dysfunction. Severe concussions can cause blindness8 and double vision. More subtle effects on vision are difficulty focusing on near objects or on digital devices (computers, tablets, and smart-phones) after a concussion.
