Hello and welcome. I'm Dr Chip
What tests were done and can you tell me what was meant by weak optic nerves?
OK but what exactly is going on with your vision?
OK. And were you told there was a specific problem with your optic nerves?
OK. The problem here is you have diabetic retinopathy--a retina problem caused by your diabetes.
I don't know why the technician said your optic nerves were weak--we don't even use the term in medicine.
Proper, tight control of your diabetes will help with your vision problem.
Please let me know if you need any more information
