@dolly1206 welcome to Mayo Clinic Connect. It sounds like we have some things in common. I was diagnosed with Type 1 Diabetes at age 18. I’m 66 now. I experienced vision problems related to diabetic retinopathy and had eye surgery at age 51, I think. The older I get on this diabetic journey, the details of the many medical events along the way become less clear. I do not know of any treatment to restore peripheral vision but if one exists it will most likely be in the realm of a specialist. What specialists do you use for your diabetic and vision care?
