Abstract BACKGROUND: The purpose of this retrospective study was to determine the frequency of occu of visual field defects in a sample of visually symptomatic, ambulatory outpatients who have brain injury (ABI), either traumatic brain injury (TBI) or cerebral vascular accident (CVA). METHODS: The medical records of 220 individuals with TBI (n 160) or CVA (n 60) were reviewed retrospectively. This was determined by a computer-based query spanning the years 2000 through The individuals’ records were reviewed to determine the frequency of targeted visual field defe were classified as scattered, restricted, homonymous, nonhomonymous, and visual neglect. altitudinal and lateral characteristics of these defects were also determined. RESULTS: In the total ABI sample of 220, some 102 (46.36%) individuals had 1 of the targete diagnosed. These defects were present in 62 (38.75%) of the TBI subgroup and in 40 (66.67% CVA subgroup. The most frequent defects in the TBI group were scattered (58.06%) follo homonymous (22.58%). In the CVA group, the most numerous were homonymous (47.5%) scattered and nonhomonymous accounting for 20% each. CONCLUSION: The uniqueness of the current study is that it reports the frequency of occurr specified visual field defects in the total ABI sample and in the TBI and CVA subgroups. Thi comparisons with other studies that generally have reported on just 1 of these groupings. The results are in accord with most of the other studies that are reviewed. The findings of this stu alert the reader to the high frequency of occurrence of visual field defects in the ABI popula make the reader aware of the adverse effects they can have on quality of life and rehabilita Optometry 2008;79:259-265
