This infant is almost 3 months old.
  • The vestibulo-ocular reflex evokes a full range of conjugate eye movements.
    • vestibulo-ocular reflex - (VOR) a reflex eye movement that stabilizes images on the retina during head movement by producing an eye movement in the opposite direction to the head movement. The purpose of this movement is to keep the image located on the centre of the visual field.
  • The baby should also be able to visually track 180 degrees in the horizontal plane.
  • Facial expression is full and symmetric.
