Study examines why brain injury may lead to vision loss

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 brainjuries, 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.
