Call your doctor and ask. The good news is that he/she said that everything looked fine so there should be no worry. Still, you have a legit question and deserve a clear answer. Don't be shy about asking questions, and don't be offended if you relay the message to a tech, who needs to ask the doc and then get back to you.
If your doctor says everything is fine, you probably don't need to worry...
I don't really know what your spots are, but they kind of resemble drusen. You can look on google images for other examples.
