How carotid artery blockage affects blood flow in the retina
Part of Brain & nervous system, Heart & circulation clinical trials.
This trial examines how a narrowing of the main neck artery (carotid stenosis) impacts blood flow in the retina using a special eye test called automated retinal oximetry. The goal is to better understand how this blockage affects eye health.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have had or will have an ultrasound of your neck arteries at the neurology department.
- The ultrasound may be for a new finding, sudden symptoms, or a routine check of known narrowing.
- You are able to sit through a standard eye exam, including looking into a device that measures oxygen levels in your retina.

Other trials that look related to this one.
This trial studies how blood flow and brain function change after a carotid artery revascularization procedure (opening a narrowed carotid artery). It may help doctors understand what to expect after treatment, especially in people with significant artery narrowing.
This study tests how well a noninvasive ultrasound measurement (the Resistance Index) can show how well blood vessels in the brain respond to a medication. It may help doctors better assess brain blood-flow health in people with certain carotid artery blockages.
This trial is testing a special ultrasound (called transcranial Doppler) to monitor blood flow during a procedure to open a narrowed carotid artery in your neck. The ultrasound helps doctors see if the procedure is safe and working well.
This trial tests a special shunt system to protect your brain during carotid artery stenting. It may help people with severe blockages in the neck artery that supplies blood to the brain.
This trial tests a stent procedure to open a severely blocked carotid artery in people who have not had a stroke or mini-stroke from that blockage recently. It aims to see if the procedure is safe and effective for preventing future strokes.
This trial tests a procedure to open a blocked carotid artery in the neck to improve blood flow to the brain. It's for people who still have symptoms (like weakness or vision problems) despite medical treatment.
