The detection of Normal Tension Glaucoma (NTG) is very challenging in clinical practice. Intraocular pressure measurement will not indicate any elevated risk for glaucoma and also the optic nerve head might appear relatively normal. In Europe up to 30 percent of primary open angle glaucoma patients have a normal intraocular pressure, in Asia the incidence of NTG is even higher.
It has been shown recently that biomechanical properties can serve as an independent risk factor for NTG1. This was the basis for the development of the Biomechanical Glaucoma Factor (BGF)².
This parameter gives you a very early risk indicator for NTG and will guide you to the best clinical decisions for your patient.
