Seeing spots, floaters and flashes in most of the cases isn't harmful.
They are a normal part of the process of growth and degeneration our eyes are destined to undergo.
In childhood, the spots and floaters, usually, are pieces of blood vessels that were left suspended inside the vitreous of the eye when it was forming before birth.
Some flashes are caused by blood vessel spasms and can occur at any age.
it's good to know that eye flashes can be a part of migraine attack, preceding the migraine headache.
However, if there is a sudden increase in the number of spots and floaters, if light flashes continue, your daughter will need more intensive medical attention.
It is good sign that her vision is not decreased and that after dilatation of pupils the doctor didn't find signs of inner eye problems.

thanks for your reply. she will having her pupils dilated tomorrow. i was getting very scared cause the thought that came in my mind was that her retina was being detached. I couldn't find anywhere on net that says that children do see floaters and are not always related to retina detachment. this was the only site that shed some light. From what the doc told me after he examined her eyes, from my thoughts only, if there was a tear in the retina he would have been able to see something as I read that the liqiud which is behind the retina would start seeping in and would have been seen during the examinition, I guess - I don't know - hope all goes well tomorrow.

But I'm 29 and this has been going on since I was 15 in high school.

I developed floaters after going through grade 9 Science class using microscopes.

Now these floaters will never go away.
