Visual field defects in children remain unrecognized due to lack of age-appropriate perimeter to assess visual fields in them. This case report highlights the case of a child who developed visual field defect following a head trauma. In this case, the use of the Pediatric Perimeter to assess the visual field aided the examiner in diagnosing the right homonymous hemianopic field loss. The conventional perimeter could not detect the defect due to low test reliability of the test for this child. The observed visual field defect correlated with the location of the brain injury and the clinical presentation of a right face turn of the child, which developed, post the head trauma. Detection of visual field defects following brain injuries are necessary for the better management and rehabilitation of the condition. The use of age-appropriate testing devices can help document visual fields in young children as well, especially when testing with conventional device is not possible. The Pediatric Perimeter is one such device for young children. © Anita Publications. All rights reserved.
