Major Signs Of A Traumatic Brain Injury
Dilated Pupils

A traumatic brain injury can cause dilated pupils, which are pupils that have become larger in size than normal. The size of an individual's pupils changes naturally depending on the amount of light in a room. In bright rooms, the pupils shrink, while they open to let in more light in dark rooms. When the pupils are dilated, though, they tend to be opened even in bright conditions. If an individual's pupils are dilated after a head injury, it may be a sign a traumatic brain injury has occurred. Sometimes dilated pupils will react to light by growing or shrinking, but they don't tend to have a proportional response to light. If the pupil is totally unresponsive to changing light sources, it's referred to as a fixed pupil.
