The child's eyes have already insomnia and can't see anymore.

Patient's question:

Around five years old

Doctor's answer:

Hello, that situation should be caused by temporary blood supply insufficiency due to spasm of the retinal arteries, which would result in those symptoms. If the symptoms only appear occasionally, it should be fine. If they have occurred several times, you should go to the hospital for a check-up to see if there is any blockage in the blood vessels.
