I agree with Terrie. Background retinopathy is "early" retinopathy. In the US, it is called NonProliferative Diabetic Retinopathy (NPDR), but is also sometimes called simplex retinopathy. These early changes include small bleeds or leakages, abnormal growth of blood vessels or fluid accumulation. These problems are all considered reversible with good blood sugar control.
While eye screening for retinopathy can be performed by an optician, optometrist or ophthalmologist, I think that once you suspect retinopathy, it is best to just see an expert, an ophthalmologist. I would not trust an optician to properly diagnose retinopathy as NPDR.
