Intraocular 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 کاملUpdate 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 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 کاملNormal Tension Glaucoma: A Different Disease?
The diagnosis and treatment of normal tension glaucoma remain controversial. The diagnostic dilemma is further compounded by the vast array of investigative modalities available. Also the concept of target IOP and physical quality of life of the patient is an important determinant of current glaucoma practice.This review provides a logical algorithm for the diagnosis, investigation and manageme...
