I was diagnosed with Type 2 a year ago but I've only just had my first diabetic eye screening test. The results show I do have some background retinopathy but do not need treatment as it doesn't affect my sight. I don't know if this happened before I was diagnosed and started treatment (Metformin) or more recently. Apart from controlling my blood sugar levels is there anything else I can do to either reverse this (if that's possible) or stop it getting worse?
