Vision and Brain Injury

Post-Trauma Vision Syndrome: Part I
Persons with a TBI or CVA frequently will experience symptoms of double vision, movement of print or stationary objects such as walls and floor, eye strain, visual fatigue, headaches and problems with balance . . . more

Post-Trauma Vision Syndrome: Part II
An unusual phenomenon that often occurs following a neurological event, such as hemiparesis or hemiplegia, is that the ambient visual process changes its orientation and concept of midline (the ambient visual process lets you know where you are in space, and provides general information needed for balance, movement, coordination, and posture) . . . more

The Neuro-Biochemical Basis of Post-Trauma Vision Syndrome
Post-Trauma vision syndrome (PTVS) describes a constellation of symptoms that evolves as secondary injury in traumatic brain injury. This syndrome includes binocular coordination dysfunctions, disorientation, loss of equilibrium, memory problems, cognitive dysfunction, loss of executive function (including reading), an inability to follow sequential instructions, fatigue, irritability, and sensitivity to light to name the most frequent symptoms . . . more

Visual Dysfunction Related to MTBI
The Visual System involves complex actions and interactions of the eyes and the brain. To simplify this description, the Visual System is being placed into three areas of function: acuity, perception, and eye movement . . . more
