2. For a person not treated when seen, do they have reduced vision due to diabetic retinopathy or maculopathy?
No: assume no harm. End of pathway.
Yes: investigate individually.
3. For a person who has treatment arranged when seen, do they have reduced vision due to diabetic retinopathy or maculopathy?
No: assume no harm. End of pathway.
