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 کاملSurgery for normal tension glaucoma.
The long term follow up of surgery in normal tension glaucoma is presented. One eye of 18 patients with bilateral progressive disease underwent fistulising surgery. Over follow up periods ranging from 2 to 7 years (50% > or = 5 years) the operated eye showed on average a 30% reduction in intraocular pressure (IOP). This was associated with a marked difference in the rate and number of retinal l...
متن کاملIntraocular pressure and central visual field of normal tension glaucoma.
AIM To study whether damage in the central 30 degrees field of normal tension glaucoma (NTG) is relatively heterogeneous or homogeneous with respect to intraocular pressure (IOP) related damage. METHODS Using the results of Humphrey perimeter examinations, the central 30 degrees field was divided into four subfields; superior and inferior hemifields excluding the caecocentral field (30-2 prog...
متن کاملComparison of OCT and HRT Findings Among Normal, Normal Tension Glaucoma, and High Tension Glaucoma
PURPOSE To evaluate the relationship between optic disc and retinal nerve fiber layer (RNFL) measurements obtained with the optical coherence tomography (OCT) and the Heidelberg retina topography (HRT) in normal, normal tension glaucoma (NTG), and high tension glaucoma (HTG). METHODS Normal, NTG and HTG subjects who met inclusion and exclusion criteria were evaluated retrospectively. One hund...
متن کاملOcular Blood Flow and Normal Tension Glaucoma
Normal tension glaucoma (NTG) is known as a multifactorial optic neuropathy characterized by progressive retinal ganglion cell death and glaucomatous visual field loss, even though the intraocular pressure (IOP) does not exceed the normal range. The pathophysiology of NTG remains largely undetermined. It is hypothesized that the abnormal ocular blood flow is involved in the pathogenesis of this...
