Normal tension glaucoma (NTG) is a common form of primary open angle glaucoma (POAG) in which there is no measured elevation of the intraocular pressure (IOP). The clinical characteristics of NTG have many similarities to those in POAG, with a few notable distinctions.

2021年8月17日 · To identify NTG suspects with IOP within the normal range and a normal VF, the inclusion criteria in this study were eyes with a larger concentric cup-to-disc ratio and/or neuroretinal rim ...

Diagnosis of normal-tension glaucoma (NTG), defined as glaucoma without a clearly abnormal IOP, depends on recognizing symptoms and signs associated with optic nerve vulnerability, in addition to absence of other explanations for disc abnormality and visual field loss.

Two NTG suspects show enlarged cup-to-disc ratio and neuroretinal rim thinning with normal-range IOP during follow-up. Both cases have baseline RNFL thickness in the normal-range on the quadrant map of RNFL OCT without definite focal RNFL defect on red-free photographs.

Normal tension glaucoma (NTG) is an optic neuropathy associated with glaucomatous optic nerve head damage, progressive retinal nerve fiber layer thinning, characteristic visual field defects, open anterior chamber angles on gonioscopy and maximum intraocular pressure (IOP) below 21 …

Normal-Tension Glaucoma (NTG), also known as low-pressure or normalpressure glaucoma, is defined as open-angle glaucoma with IOP within the normal range. Its pathogenesis is not yet fully understood, and there is debate whether it represents a subset of Primary Open-Angle Glaucoma (POAG) or represents heterogeneous diseases.

2018年2月19日 · Normal tension glaucoma (NTG) is an exception in the “glaucoma family” where the major risk factor, increased intraocular pressure, is missing. If not...

aims to determine the frequency of Normotension Glaucoma (NTG) in patients with a high cup-to-disc ratio who were referred to the clinic. Materials and Methods: This cross-sectional descriptive study includes 100 patients with a cup-to-disc ratio above 0.3 and normal eye pressure.

NTG as a type of open-angle glaucoma (OAG) is characterized by a multifactorial inheritance and complex pattern. Many researchers have found a potential higher incidence of glaucoma in both the first- and second-degree relatives, with a relative risk higher than 10 folds higher among first-degree relatives [6].

Results: Retinal nerve fiber layer thickness (RNFLT) based on OCT measurements was significantly reduced (thinner) in the superior to superonasal sectors and significantly greater (thicker) in the inferotemporal sector in the SSOH group than in the NTG group. The cup was significantly smaller and the rim significantly larger in the ...
