The Claim

Prolonged hyperglycemia and hypertension are strongly associated with the development and progression of diabetic retinopathy through interconnected mechanisms including oxidative stress, advanced glycation end products, inflammation, and vascular endothelial growth factor (VEGF) activation.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

Long-term high blood sugar and high blood pressure are linked to the worsening of diabetic retinopathy through biological processes involving oxidative stress, accumulation of glycation products, inflammation, and activation of vascular endothelial growth factor.

See the scientific wording

Prolonged hyperglycemia and hypertension are strongly associated with the development and progression of diabetic retinopathy, acting through interconnected mechanisms including oxidative stress, advanced glycation end products, inflammation, and vascular endothelial growth factor (VEGF) activation.

Why this might work

High blood sugar and high blood pressure damage tiny blood vessels in the eye by producing harmful molecules that trigger inflammation and cause abnormal blood vessel growth, leading to leakage and vision loss.

What the research says

1 study
  1. Study: Diabetic retinopathy

    High blood sugar and high blood pressure over time damage the eyes of people with diabetes, and this happens because of harmful processes like inflammation and abnormal blood vessel growth. Controlling sugar and blood pressure helps prevent this damage.
