  1. *PL+: able to perceive light; PR+: able to report the location of light; FC: able to count fingers at n meters.
  2. BM: Biological motion; GM: Global motion.
  3. **Degree if noise at which a hit rate of 82% was reached (high values indicate high sensitivity) in the behavioral BM task.
  4. ***Percentage of coherence level necessary to reach a hit rate of 82% (high values indicate low sensitivity) in the behavioral GM task.
  5. Note patient dc-a was categorized as dc due to parents’ reports supported by a low nystagmus and the achieved high visual outcome.
