Several emotions should spring to mind when you see this "White and Wide" appearance of the eyes. One is fear, another is severe anger (rage) and a third is surprise. None of these emotions are present here however. Another possible cause is medical - lid retraction can be a sign of hyperthyroid disease.
People also open their eyes extra wide when they are emphasizing certain points during conversation - but this rarely happens without a coexisting forehead muscular contraction (particularly so often). Such a forehead contraction only occurred twice during this video clip - once at 0:50 when she says, "...children..." and another time at 0:54 when she says "...you guys..." Even during these two occasions her forehead is considerably hypo-reactive.
The reason for Ms. Maldonado's prolonged, repeated and extreme eyelid opening is secondary to botox treatments to her forehead. While not a common side effect of botox, it is certainly not rare. When the forehead cannot move as it typically does, the eyelids will over dramatically over-compensate and open in this extreme fashion. This can give a very unusual appearance that most often people will describe as fear - but also angry or even "creepy". Two additional examples are shown below.
What other unusual body language - facial expression do you see in this video which is another "False Fear" signal?
