Current function did not correlate with initial injury severity. Among patients in rehab for traumatic brain injury, the initial severity of injury was not significantly correlated with functional status, but metrics from a bedside eye-tracking system were, according to a study in Frontiers in Neurology. Perspective from Vanessa Huang, OD, FAAO “Eye movements are commonly examined after neurological injury, but in routine clinical practice, smooth pursuit is often assessed qualitatively by asking a patient to follow a handheld target,” study authors Shimrit Shani, a PhD student in the School of Optometry and Vision Science at Bar-Ilan University, Israel, and Yoram S. Bonneh, PhD, professor at the university, told Healio. “We wanted to see whether we could take this simple clinical behavior of following a moving target and turn it into an objective, quantitative bedside assessment.” To examine this potential, the researchers used an eye-tracking system on 30 adults undergoing inpatient rehabilitation for traumatic brain injury (TBI) as well as 30 controls. Shimrit Shani The patients were instructed to follow moving targets on a 14” laptop monitor while an eye-tracking system (Tobii Eye Tracker 4C, Tobii) captured metrics of oculomotor function from a distance of about 60 cm. The target was a white circle moving in random directions outward from the center of a black screen. “Without restraining the head, we were able to extract several complementary measures from a brief linear tracking task, including smooth pursuit and catch-up saccade behavior, predictive tracking when the target was temporarily hidden, pupil response and binocular coordination,” Shani and Bonneh said. “We deliberately kept the task simple and clinically practical.” Additional tests were run where the circle passed beneath an occluder disc of varying size and color and was temporarily invisible. Yoram S. Bonneh “This allowed us to ask not only how well patients followed a visible target but whether they could anticipate its trajectory when visual information was briefly unavailable,” the researchers told Healio. Patients did these activities three times on average, and the results were compared with an age-matched control group of equal size that completed activities one time. Their oculomotor results were compared with two measures of clinical condition: Functional Independence Measure, which measures the current ability to perform everyday activities independently, and Glasgow Coma Scale, which is “a widely used clinical measure of the level of consciousness after brain injury and is commonly used to classify TBI severity,” the researchers said. According to the results, all six oculomotor metrics had significant differences between patients with TBI and controls. The metrics were “remarkably correlated” with Functional Independence Measure. However, the researchers found no significant correlation between Functional Independence Measure and initial Glasgow Coma Scale score. The metric most strongly correlated was occluder-induced deviation, or the patient’s ability to follow the target while it was hidden behind the occluder disc. Controls would “jump ahead” to the outside of the occluder disc where the target emerged, while patients with TBI lagged behind the target, according to the study. According to Shani and Bonneh, this metric suggests “that TBI may affect not only the mechanics of following a moving object but also the brain’s ability to predict its future position when visual information is temporarily unavailable.” The results suggest that eye tracking could be an “objective, quantitative extension” of subjective eye evaluations currently performed, the researchers said. “Just a few minutes of visual tracking yielded measures of pursuit, saccadic correction, prediction, pupillary response and binocular coordination, measures that were associated with the patient’s current functional status,” Shani and Bonneh told Healio. “The next crucial step is longitudinal validation. We need to determine whether changes in these measures within an individual patient can reliably track recovery or response to rehabilitation and whether these measures may also have prognostic value.”
