Concussion may be under-diagnosed because of the lack of the highly noticeable signs and symptoms while athletes may minimize their injuries to remain in the competition. [76] Direct impact to the head is not required for a concussion diagnosis, as other bodily impacts with a subsequent force transmission to the head are also causes. [ 77 ]
Raccoon eyes, also known as panda eyes or periorbital ecchymosis, is a sign of basal skull fracture or subgaleal hematoma, a craniotomy that ruptured the meninges, or (rarely) certain cancers. [ 1 ] [ 2 ] Bilateral hemorrhage occurs when damage at the time of a facial fracture tears the meninges and causes the venous sinuses to bleed into the ...
All of these causes can be put into two categories used to classify head injuries; those that occur from impact (blows) and those that occur from shaking. [27] Common causes of head injury due to impact are motor vehicle traffic collisions, home and occupational accidents, falls, assault, and sports related accidents. Head injuries from shaking ...
The visual anomaly results from abnormal functioning of portions of the occipital cortex at the back of the brain, not in the eyes nor any component thereof, such as the retinas. [3] This is a different disease from retinal migraine , which is monocular (only one eye).
These can be due to concussion injury to the brain and is associated with subdural haemorrhage and unconsciousness. The parasympathetic fibers to the pupil are responsible for pupillary constriction. The fibers pass through the periphery of the oculomotor nerve, and hence are the first to be affected in case of compression of the nerve.
Every normal mammalian eye has a scotoma in its field of vision, usually termed its blind spot. This is a location with no photoreceptor cells, where the retinal ganglion cell axons that compose the optic nerve exit the retina. This location is called the optic disc. There is no direct conscious awareness of visual scotomas.
