People with normal tension glaucoma tend to have thinner corneas than average, which may mean that we are underestimating their true intraocular pressures.
Comment: This study suggests that anthocyanins and ginkgo may improve visual function in individuals with normal tension glaucoma.
WuDunn: Basically, normal tension glaucoma is treated not very differently than regular glaucoma in that we try to lower the intraocular pressure.
The Foundation for Glaucoma Research has a 13-year history of coordinating national and international research, including the Glaucoma Research Eye Donor Network, which provides glaucomatous eye tissue to researchers, and the Normal Tension Glaucoma Study, a widely respected and important international study which the foundation manages and helped design.
Intra ocular pressure (IOP) can be elevated, or be at a normal level, which helps to differentiate between normal tension glaucoma (NTG) (the latter) from primary open angle glaucoma (POAG) (the former) ere are also those who have order hypertension or 'suspicious' discs, who are deemed to be as risk of developing POAG.

28) However, OAG frequently occurs at levels of IOP below 21mmHg and is often referred to as normal tension glaucoma (NTG), although Spry and Harper note that this division of COAG into NTG and those with IOPs greater than 21mmHg (sometimes referred to as High Tension Glaucoma) is regarded by many as an arbitrary one, with both types of glaucoma being part of the spectrum of the disease.
Research about the recently discovered Optineurin gene and its mutations, which has been associated with POAG and in particular normal tension glaucoma (NTG), will also be presented.
One patient was referred for progressive normal tension glaucoma (NTG) but this was not confirmed and the patient was discharged.
This mutation, which is licensed to InSite Vision, is being reported to be a marker for normal tension glaucoma and possibly also steroid induced glaucoma.
