It is, I hope you appreciate, very difficult to be certain about the diagnosie wihout actually seeing your daughter. It would, however, seem that your daughter is developing a small patch of leucoderma. This might at first instance seem discouraging to you but it is not so. Most children (and adults) respond to treatment for leucoderma fairly well. It is particularly easy in children and on the eyelids. You should therefore consult with a dermatologist who could confirm the diagnosis and advise about appropriate treatment. I am reasonably confident your child will improve.
