This paper does, and also tries to predict where you are looking based on cursor activity, rather than just rely on the cursor's current location:

"But claiming that the cursor approximates the gaze is misguided - as we have shown, this is often not the case depending on time and behavior"

"Therefore, we conclude that whether the subject tracks their gaze closely with their cursor is more likely to stem from personal habits rather than age or gender."
