Ocular Blood Flow Assessment in Glaucoma

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.

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 \
