Multiple Choice

Which combination best describes the features associated with cerebral visual impairment?

Cerebral visual impairment results from how the brain interprets visual input, not from the eyes themselves. The pattern described here captures the typical CVI profile: an abnormal light response shows that light and glare processing is atypical at the cortical level; avoidant social gaze reflects difficulty with processing faces and social visual information; poor visual acuity can occur even with a healthy eye because acuity depends on brain interpretation; fatigue with visual tasks happens because the brain uses more effort to make sense of visual scenes; and increased attention to color and movement indicates reliance on simpler, dynamic cues that are easier to process when higher-order visual processing is challenged. Together, these features point to a brain-based visual impairment. The other options describe eye-related problems or less typical patterns and don’t fit the CVI pattern.
