How would you draw Ghost eyes in sprite form?

okay so everyone knows that ghosts have white eyes, mainly shown with the Aradia ghost where her eyes are white.

The only ghost kid we've seen properly is ghost John, whose eye dots just dissapear but we can see he has his glasses there so those work as his eyes.

But what if Rose became a ghost?? would she have no eyes at all?? or would her eyes be figurated? like, have a shape defined like the trolls.

This is a bit difficult since all the kids have white #FFFFFF skin
