Background : Glaucoma is a common disease, potentially blinding, characterized by progressive damage to the optic nerve. If the intraocular pressure is the most known risk factor, however, there are cases of glaucoma scalable despite well-controlled intraocular pressure, ocular hypertension without glaucoma or glaucoma without ocular hypertension (normal tension glaucoma).
Purpose :Involvement of vascular factors in the development of glaucoma and scalability has been proved, associated with a possible loss of vascular autoregulation. The objective of this study is to quantify MRI flow of blood flows referred ophthalmic patients with glaucoma untreated comparison with control subjects.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Adult participants
* Diagnosis of primary open angle glaucoma or normal-tension glaucoma
* Never received any anti glaucoma therapy
* Patients included in the group " normal pressure glaucoma " are patients where the diagnosis of optic neuropathy have been worn by the ophthalmologist with measured intraocular pressure \<21 mmHg.
* Healthy controls will be examined by an ophthalmologist before inclusion
Exclusion Criteria:
* Anyone with a classic contraindication to MRI
* Cardiovascular comorbidities or neurovascular : uncontrolled systemic hypertension , Diabetes, heart failure , carotid stenosis , ischemic stroke or transient ischemic attack.
* Already treated glaucoma
* Prescription by the ophthalmologist another treatment than prostaglandin analogue treatment.
* Other clinical forms of glaucoma : angle closure glaucoma, neovascular glaucoma, exfoliative glaucoma, secondary glaucomas, pigment dispersion glaucoma, traumatic glaucoma, congenital glaucoma
* Presence of other ocular pathology (simple refractive error allowing 10/10 of best corrected visual acuity and mild and moderate cataracts will not be considered as a criterion for non- inclusion).
* History of intraocular or orbital surgery of less than 6 months .
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
