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 |
