At Georgia Eye Physicians and Surgeons, we are actively involved in research relating to all aspects of vision.  One particularly interesting use of the latest visual diagnostic technology is the early detection of mild traumatic brain injuries, or concussions.  The majority of concussions are the result of blunt trauma, or a blow to the head, and in children they are most commonly sustained during contact sports such as football, soccer, lacrosse, and hockey.  Traumatic brain injuries like concussions often have wide-ranging physical and psychological effects, some appearing immediately after the traumatic event, and many others that may not appear until days or even weeks later.  In fact, it is estimated that the vast majority of concussions (approximately 90%) do NOT result in a loss of consciousness, making diagnosis more challenging than previously thought.  As a result, concussions are often misidentified as ‘low severity’ injuries.  Patients are frequently treated with a ‘sit-and-wait’ approach, and it is only after symptoms have become debilitating that people seek care of their own accord.

Treating Your Eye Condition with Specialized Surgery Since an estimated 3.8 million recreation and sport-related concussions occur in the United States every year, many are looking for better ways to help diagnose concussion patients so that prompt treatment can be rendered.  Although concussions are not visible in routine scans of the brain, they are detectable when important aspects of brain function are measured.  This is where an optical examination can act as an invaluable diagnostic tool.  More than 50 percent of the neural connections within the brain are involved with some aspect of vision, so many of the earliest signs of traumatic brain injury can be detected by examining the function of the cranial nerves involved in vision and eye movement.  For example, damage to the nerves that control the tiny dilations and contractions of the pupil may also cause the pupils to react differently to light or to even be different sizes.  Additionally, most individuals that have suffered a concussion will complain of vision related problems, such as blurry vision, light sensitivity (photophobia), eye fatigue, double vision (diplopia), or reading difficulties.  Quick, easy to administer sideline visual tests, like the King-Devick Test, have been developed to accurately assess the likelihood of concussion following injury.

Optometrists and ophthalmologists are also crucial in helping rehabilitate patients’ vision after such an injury has been sustained.  Because so many of the connections within the brain are involved with the process of vision, it is hardly surprising that vision problems are so common following an acquired brain injury.  Concussions can result in a reduction in the eye’s focusing ability, resulting in blurred vision at close or far ranges.  This inability to focus can eventually result in headaches, eyestrain, or even double vision when performing tasks that require close focus, such as reading.  Many of the visual conditions that result from a concussion can be successfully managed with prescription eyeglasses or contact lenses, even a relatively small prescription correction can often decrease blurred vision enough to eliminate eyestrain and its related symptoms.
