Update on Normal Tension Glaucoma
Normal tension glaucoma (NTG) is labelled when typical glaucomatous disc changes, visual field defects and open anterior chamber angles are associated with intraocular pressure (IOP) constantly below 21 mmHg. Chronic low vascular perfusion, Raynaud's phenomenon, migraine, nocturnal systemic hypotension and over-treated systemic hypertension are the main causes of normal tension glaucoma. Goldma...
متن کاملNormal tension glaucoma--a practical approach.
Normal tension glaucoma (NTG) remains a diYcult diagnosis for the ophthalmologist who favours the argument that raised intraocular pressure (IOP) is essential for the diagnosis of primary open angle glaucoma (POAG). The concept of NTG challenges us to distinguish between pressure dependent and pressure independent causal factors. The purpose of this review is to present some of the current info...
متن کاملOcular dimensions in low tension glaucoma compared with open-angle glaucoma and the normal.
Pathological excavation of the optic disc in the apparent absence of raised ocular tension was first described by von Graefe (1857), and since then it has aroused interest among ophthalmologists; various names have been given to it and these have reflected ideas about its aetiology. Schnabel (I885) described a cavernous optic atrophy which he believed had resulted from progressive diminution of...
متن کاملReduction in blood glutathione levels occurs similarly in patients with primary-open angle or normal tension glaucoma.
PURPOSE To investigate in parallel the systemic glutathione levels of patients suffering from primary open angle glaucoma (POAG) or normal tension glaucoma (NTG) with comparable functional loss. METHODS Thirty-four POAG patients, 30 NTG patients, and 53 controls were subjected to blood analysis to detect the level of circulating glutathione in its reduced (GSH) and oxidized (GSSG) forms. Syst...
متن کاملOcular blood flow alteration in glaucoma is related to systemic vascular dysregulation.
AIMS To investigate the source of ocular blood flow alterations in glaucoma. METHODS In 56 patients with open angle glaucoma, blood flow parameters were obtained from both eyes in the ophthalmic and central retinal artery by means of colour Doppler imaging, as well as in the choroidal circulation and the neuroretinal rim of the optic nerve by means of laser Doppler flowmetry. Based on these h...
