Studying optic nerve blood flow in different eye conditions
Part of Brain & nervous system, Eyes & vision, Genetic & congenital, Heart & circulation, Hormones & metabolism clinical trials.
This study looks at how blood flows in the optic nerve (the nerve that carries visual information from the eye to the brain) using advanced imaging. It aims to better understand different optic nerve conditions, which may help improve diagnosis and treatment in the future.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be able to agree to take part in the study (or a parent/guardian must agree for you).
- You must have a diagnosis of optic nerve swelling or damage, such as NAION, optic neuritis, papilledema, LHON, optic disc drusen, normal-tension glaucoma, or other optic nerve conditions.
- You cannot have any other eye disease (like retinal disease) or an eye condition that would make it hard to see the optic nerve clearly.
- You should not have significant cloudiness of the eye's lens or other media that would affect the quality of the blood flow images.
- If you have Alzheimer's or Parkinson's disease, your data will be collected separately and not compared directly.

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 study looks at how the optic nerve (the part of your eye that sends images to your brain) strains or bends in people who do not have glaucoma. It uses advanced eye imaging and home pressure checks to understand the nerve's health.
This study tracks changes in blood flow, structure, and vision over time in people with glaucoma or high eye pressure. It aims to understand how these conditions progress, which could help improve future treatment.
This study tests new, non-invasive ways to measure how the retina (the light-sensing part of the eye) is structured and how well it works. It may help researchers better understand certain vision disorders and how to track them, without surgery or injections.
This study uses advanced eye scans to compare the eyes of people with glaucoma against those with healthy eyes. It aims to find better ways to detect and monitor glaucoma, which could help preserve vision.
This study uses MRI scans to look at inflammation in blood vessels around the eye in two conditions: giant cell arteritis (GCA, a type of blood vessel inflammation) and ischemic optic neuropathy (a condition where the optic nerve doesn't get enough blood). The goal is to better understand how inflammation affects the optic nerve and vision, which could help guide future treatments.
