How Blood Sugar Affects Eye Blood Vessels in Diabetes
Part of Eyes & vision, Heart & circulation, Hormones & metabolism clinical trials.
This study looks at how blood sugar control (measured by HbA1c) relates to tiny blood vessel changes in the back of the eye in people with diabetes. It uses a special camera (OCTA) to take detailed pictures of the retina without needing a dye injection.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have diabetes and diabetic retinopathy (changes in the back of the eye caused by diabetes).
- You have had your HbA1c tested (either well-controlled or not well-controlled).
- You have not had any eye injections (like anti-VEGF) or laser treatment for your eyes.
- You have not had any previous eye surgeries, including cataract surgery.
- Your eye is clear enough for the camera – no dense cataracts or other cloudiness.
- You do not have other eye diseases like a blocked vein in the eye, macular degeneration, or uncontrolled glaucoma.

This study looks at how fat and sugar levels in the blood relate to different stages of eye damage in people with type 2 diabetes. It may help find new ways to treat or prevent vision loss.
This study uses a special eye imaging test called OCT angiography to look at tiny blood vessels in the back of the eye. It aims to understand changes caused by diabetic retinopathy, which could help improve how we monitor and treat this condition.
This study follows people with type 2 diabetes to understand how diabetic retinopathy (an eye disease caused by diabetes) changes over time without treatment. It may help if you have no other eye issues causing new blood vessels and are not planning for certain eye procedures.
This study observes how diabetes affects vision over time in people with diabetes. It helps doctors better understand eye health without any treatment or intervention.
This study follows patients with diabetic eye swelling (a complication of diabetes affecting the macula, the part of your eye needed for detailed vision) who are receiving anti-VEGF injections—a standard treatment that reduces abnormal blood vessel growth. Researchers will measure how well your retina (the light-sensitive tissue in your eye) recovers and functions over time.
This study measures blood flow in the eyes and how the retina (back of the eye) uses oxygen in people with diabetes who are starting a new type of diabetes medication. Researchers want to understand how these newer medications affect blood vessels in the eyes.
