Stellate ganglion block and retina blood flow study
Part of Brain & nervous system, Heart & circulation, Injuries & trauma clinical trials.
This trial looks at how a nerve block (stellate ganglion block) affects blood flow in the retina. It may help people who already get this block for conditions like complex regional pain syndrome understand eye effects.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older
- You are already scheduled to receive a stellate ganglion nerve block for an approved condition like complex regional pain syndrome
- You are not pregnant
- You speak English
- You are able to sit up and look into an eye-imaging device

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 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.
This study uses a special imaging test (OCT angiography) to look at blood flow around the optic nerve in people with advanced glaucoma. It aims to better understand how glaucoma affects eye circulation, which may help improve future care.
This trial tests a tiny needle injection into the artery to dissolve a blockage in the eye's main blood supply. It may help restore vision if the blockage happened within the past week.
This trial tests if a nerve block near the neck can improve brain function recovery after a subarachnoid hemorrhage (a type of stroke from a bleeding brain aneurysm). It is for people within 72 hours of onset who are having surgery to fix the aneurysm.
This study uses a special eye scan (OCTA) to check the health of tiny blood vessels in the back of the eye. It may help doctors understand small vessel disease in the brain and find easier ways to monitor it.
