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.

2022年12月12日 · Glaucoma is characteristic of progressive optic neuropathy, featuring optic disc cupping and visual field loss, associated with raised intraocular pressure (IOP). Normal-tension glaucoma (NTG), also known as normal or low-pressure glaucoma, is open-angle with a presenting IOP in the normal range.[1]

Normal tension glaucoma (NTG) is an optic nerve neuropathy that presents with optic disc excavation, visual field loss in spite of intraocular pressure <21 mm Hg. Progressive visual field loss and disc excavation can continue despite of pressure lowering of 30% of IOP.

To document the clinical features of disc hemorrhage in patients with branch retinal vein occlusion (BRVO) and normal tension glaucoma (NTG), and to evaluate the relationship between BRVO and NTG with disc hemorrhages.

Disc hemorrhages are characteristic linear hemorrhages perpendicular to the optic disc, most commonly on the superotemporal or inferotemporal margin. The cause of disc hemorrhages has not been fully characterized, and mechanical and vascular hypotheses with evidence supporting both have been proposed.

2021年8月17日 · NTG suspects taking medication for systemic hypertension, disc torsion of the optic disc in the inferotemporal direction, and thinner LC of the optic nerve head at baseline were at greater...

Normal-tension glaucoma (NTG) is a multifactorial optic neuropathy which, similar to open-angle glaucomas, is characterized by progressive retinal ganglion cell death and glaucomatous visual field loss. The major distinction of NTG from open-angle glaucomas is that the intraocular pressure (IOP) does not exceed the normal range.

2009年7月24日 · In normal tension glaucoma (NTG), optic disc haemorrhage is known to be a significant negative prognostic factor. 1 The haemorrhage typically shows a flame- or splinter-like shape at the border...

One hundred thirty stereo photographs of optic discs in patients with normal tension glaucoma (NTG) were reviewed in order to identify characteristics of the three following types of NTG: focal ischemic, senile sclerotic, and generalized cup enlargement.

2007年2月1日 · Normal-tension glaucoma (NTG) is a form of open-angle glaucoma characterized by glaucomatous optic neuropathy in patients with IOP measurements consistently lower than 21 mmHg.
