Our not quite 4 month old siamese has this and is having reconstructive surgery in about an hour. Apparently it's a congenital defect that occurs most frequently in cats, where the upper eyelid doesn't fully develop.
I'll be crossing my fingers for the surgery to go well. Good luck Zeus!
EDIT: Just spotted my typo in the title, Dangit!!
