Study of enlarged eye blood vessel changes
Part of Eyes & vision clinical trials.
This study looks at how certain enlarged blood vessels in the back of the eye change over time. By taking special images, researchers hope to learn more about these vessels. It might help if you have been told you have pachyvessels.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 45 years old or older.
- You need to have enlarged blood vessels (called pachyvessels) in the back of your eye, seen on a special wide-field image.
- You must be willing to have your pupils dilated and complete all the eye tests required for both eyes.
- You cannot have other serious eye problems, such as injury, infection, or prior eye surgery (except cataract surgery).
- You cannot have health issues that affect blood flow, like uncontrolled high blood pressure, autoimmune diseases, or blood disorders.

This study looks at how blood flow changes in the eye after a type of retinal detachment surgery called scleral buckling. It uses imaging to check the eye's blood vessels, and may help doctors understand recovery better.
This study looks for new ways to diagnose and track eye disorders using imaging and genetic tests. It may help find better treatments for conditions linked to blood vessel and nerve problems in the eye.
This study uses a special eye scan to look at the back of the eye in people with central serous chorioretinopathy (CSC). It aims to better understand the condition and may help guide future treatments.
This study uses advanced eye imaging (OCT and OCTA) to understand how the blood vessels and tissue layers in the back of the eye differ between people with glaucoma, people at risk for angle-closure glaucoma, and people with healthy eyes. The findings may help doctors better diagnose and understand these eye conditions.
This study uses an advanced eye scan (OCT-A) to look at tiny blood vessels in the back of the eye. It compares people with systemic blood vessel conditions (like high blood pressure or inflammatory disease) to healthy volunteers, to see if the eye scan can help predict or understand these diseases.
This study looks at blood flow in a layer of the eye called the choriocapillaris in people with pseudoxanthoma elasticum (PXE). It compares these findings with healthy volunteers to understand eye changes before they become severe.
