Gamat EyeWorld Contributing Writers Sports-related head injuries can be as devastating as military blasts when it comes to visual issues stemming from TBI W hen it comes to brain trauma and related visual issues, military blast traumatic brain injury (TBI)-related vi- sual dysfunction and ocular patholo- gy resulting from sports-related head injuries can be equally devastating. Brain injury and visual responses According to a 2009 report on invisible wounds of war, 31,501 U.S. service members had been wounded due to hostile action during their operations in Iraq. For the period from January 2003 to March 2006 alone, 28% of patients admitted to the Walter Reed Army Medical Cen- ter were diagnosed with TBI, with powerful explosions being the main cause. The majority of severe eye injuries reported between 2003 and 2005 were caused by a blast, and among patients with blast injuries, 61% had TBI. Meanwhile, effective screening methods in the detection of TBI in patients without major physical injury have been imple- mented only recently. Common ocular injuries found in veterans include damage to the cornea, trabecular meshwork, lens, retina, and optic nerve, which are all potential threats to vision and require long-term monitoring. In addition, TBI can lead to neuro-oph- thalmic issues such as visual field abnormalities, double vision, and nystagmus—conditions that critical- ly affect performance of an individ- ual's normal daily activities such as reading and driving. In the world of athletes, repeat- ed brain trauma has long been asso- ciated with neurological deteriora- tion. Since the 1920s, this has been seen in professional boxing. The condition, now known as chronic traumatic encephalopathy (CTE), is clinically associated with memory disturbances, behavioral and per- sonality changes, Parkinsonism, and speech and gait abnormalities.
