Pennsylvania residents may already know that head injuries, including injuries to the brain, can be incredibly serious, especially when they result in additional complications. One significant complication that can follow a brain injury is the permanent loss of one's sight. However, one study has shed light on why a brain injury sometimes causes a person to lose his or her sight.
According to the study, uncontrolled inflammation caused by white blood cells was behind the loss of sight following a brain injury. White blood cells are sent to the optic nerve by a certain protein receptor when the damaged nerve tissue produces a binding protein. If the first protein is blocked or deleted, there is less optic nerve damage and the nerve is able to function correctly.
One serious complication of a brain injury is vision loss. Vision loss can be a permanent disability, resulting in significant medical expenses and the need for ongoing medical care and rehabilitation. This can quickly drain a person's finances, especially if the person is unable to work.
A number of things can cause brain injuries, but often, they are caused by otherwise preventable accidents. For example, a car accident caused by a negligent driver can cause a brain injury. Falls on slippery surfaces can also cause head injuries, as can sporting accidents. However, if a person's brain injury is the result of another person's irresponsible and negligent actions, the accident victim may want to pursue a lawsuit, to obtain compensation for his or her losses.
