I went to hospital for tests as I have 1 sided numbness dizziness and the consultant said I have a pale retina in 1 eye. What can this mean?

Pale retina. Please repost: Did the consultant remark that you have a pale retina while (s)he was looking in your eye? If so, did you ask him/her right then what it could mean? If so, what was the answer? If not, why not? If (s)he did not say this during the exam, where is it stated?
