Symptoms in 5 year old

[palore]

My brother and his wife are worried about my 5year old niece. Twice in a few months she woke saying she couldn't see out of her left eye for a couple of minutes (except for dark blue or black) and she has been complaining that the sun is too bright (they are in Australia at the moment) even when it has been cloudy. The doctor has dismissed wanting to see her again in six weeks. Does anyone have experience of these symptoms and know what may be wrong?
