My baby is 6 weeks old and a couple days ago I noticed a light brown spot in her eye along with a couple light red veins in both eyes. In the photo I posted it looks more reddish but now it looks mostly brown. I took her to a pediatric ophthalmologist this morning and she said the brown spot could be a freckle and if it gets bigger to bring her back. I felt like she rushed through the examination. I'm still worried something is wrong. Any advice is greatly appreciated, thanks.
