Hello AJ,
I'm sorry to read of what is happening with you daughter. I imagine it would be very worrying.
When you went to the vision clinic did you see an actual Opthalmologist?
Does your daughter have any other health issues at all? No diabetes for example?
I'll leave the link to the
Children's Health forum
and also this one below which might get more viewers.
General Health Conditions & Rare Disorders forum
Use the same title if you post again as that might draw in people who have heard of this happening. (Pink Vision in one eye).
I hope you find answers and this ends up being a very temporary problem for your daughter,
take care there.
