TABLE 6

Visual Characteristics and Behaviors in Cortical Visual Impairment

Visual Characteristics and Behaviors
Degree of vision loss unexplained by ocular findings 
Fluctuating level of vision 
Improvement in vision over time 
Poor visual fixation 
Preference for staring at lights (but some may have photophobia) 
Better vision for moving versus stationary objects (but may have impaired perception of movement in some cases) 
Better vision in familiar environments 
Distinct color preferences 
Pronounced head turns to search for objects (possibly to make use of residual peripheral vision) 
Poor depth perception 
Difficulty differentiating between background and foreground visual information 
Difficulty maintaining visual attention 
Visual field deficits 
Flicking fingers in front of the eyes for self-stimulation
