Colored spots in vision daily that come and go and have had constant visual aura for 15 years. mri eeg blood work eye exam all normal. what is this?

Retinal exam: Floaters are usually not described as having colors. The description you provide does not suggest a single problem but may be due to pathology of the retina not observed in your exam. Did an ophthalmologist perform your exam? If so, may I suggest that you are having a variant of migraine. Ask your primary care doctor if this is a possibility.
