Although traumatic brain injury (TBI) is a well-recognized consequence of extreme blast waves, it is less appreciated that over 80 percent of combat veterans with TBI also develop visual problems. A new study reports that blast exposure that does not cause detectable changes in the brain can result in long-term retinal injury. Researchers identified early indicators of retinal injury and inflammation that may help detect individuals at risk of visual impairment who would then benefit from more timely treatment.
