The Claim
Optimal control of blood glucose and blood pressure prevents the onset and slows the progression of diabetic retinopathy.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Maintaining blood glucose and blood pressure within target ranges prevents diabetic retinopathy from developing and reduces its worsening over time.
See the scientific wording
Optimal control of blood glucose and blood pressure is the cornerstone for preventing the onset and slowing the progression of diabetic retinopathy.
High blood sugar and high blood pressure damage the tiny blood vessels in the retina by producing harmful molecules that trigger inflammation and cause blood vessels to leak and grow abnormally. This damage is worsened when nerve cells in the retina die, which cuts off signals that keep blood vessels healthy, leading to more vessel loss and abnormal growth.
What the research says
1 studyStudy: Diabetic retinopathy
Keeping blood sugar and blood pressure under control is the most important way to stop diabetes from damaging the eyes, according to this study. Other treatments help too, but controlling these two things is the foundation.
