Low uptake of screening for retinopathy during pregnancy with pre-existing diabetes: A population-based cohort study
Authors' conclusion
Uptake of eye screening in the first trimester among people with pre-existing diabetes was extremely low, despite the risk of worsening and sight-threatening retinopathy during pregnancy. Even by the end of pregnancy, fewer than one-half of patients had received eye screening.

18.7 %
Eye screening at any time during pregnancy

Further findings
Factors associated with screening
- Highest eye screening rates with prior retinopathy treatment, longer diabetes duration, and on the insulin pump program
- Care from an endocrinologist in the first 180 days of pregnancy: far more likely to have an eye examination
