Dysregulation humoral blood pressure glaucoma
WebIn normal-tension glaucoma (NTG), optic nerve damage occurs despite a normal intraocular pressure. Studies implicating systemic blood pressure or, more recently, arterial stiffness in the pathophysiology of NTG have produced conflicting results. Our aim was to investigate whether NTG is associated with alterations in the macrocirculation or ... WebThe pathogenesis of glaucoma remains an active area of ophthalmic research. Both mechanical and vascular factors may contribute to glaucomatous optic neuropathy. In this article, Dr. Weinreb and colleagues discuss the role of vascular dysregulation, specifically low ocular perfusion pressure, in both the development and progression of glaucoma.

Although intraocular pressure (IOP) remains an important risk factor for glaucoma, it is clear that other factors can also influence disease development and progression. More recently, the role that blood pressure (BP) has in the genesis of glaucoma has attracted attention, as it represents a clinically modifiable risk factor and …
WebThe term dysregulation simply means that blood flow is not properly adapted to this need. Dysregulative mechanisms can lead to an over- or underperfusion. A steady overperfusion may be less critical for long-term damage. A constant underperfusion, however, can lead to some tissue atrophy or in extreme situations to infarction. WebDiagnosis.
