Background: Mild traumatic brain injury (MTBI) is the least brain injury due to direct or indirect blow to the head, which according to the Glasgow scale is given a score between 13 and 15. The findings indicate cognitive impairment. Perceptual dysfunction is one of the most important cognitive deficits in these patients. The present study was designed and performed to compare MTBI patients with healthy individuals in terms of visual perception error (VPE).
Materials and methods: In this causal-comparative study, 30 MTBI patients, in the range of 15-45 and mean age of 27 years and 10 months, with a diagnostic history of less than one year in Ilam hospitals, and 30 healthy individuals in the same range and mean age of 29 years and 7 months (both groups with equal sex) were randomly selected and assessed by VPEMT. Data were analyzed by independent t-test and Levin using SPSS 23.  
Results: The results showed that the mean VPE in patients with MTBI with unequal variances (P <0.05), at the level of 95% is significantly higher than healthy individuals (P <0.05).
Conclusion: This finding, consistent with the results of previous research, indicates the chronic cognitive consequences of concussion, even at a mild level, at least up to one year after injury, and causes a sharp increase in VPE. It is necessary to pay attention to visual perception errors in clinical and legal evaluations of these patients. However, a definitive judgment in this regard requires future research.
Keywords: Mild traumatic brain injury, Visual perception error, Visual perception error test (VPEMT)
