Challenges In Early Glaucoma Detection
INTRODUCTION Glaucoma is the most common optic neuropathy which is characterized by progressive loss of retinal ganglion cells, the excavation of the optic nerve head, associated with defects in the visual field. It is not a disease, but the final result of united and yet completely unidentified cellular and subcellular processes and effects of many factors responsible for changes in retinal ga...
متن کاملEarly detection of glaucoma.
Primary open-angle glaucoma (often loosely called "chronic glaucoma") is one of the main causes of preventable loss of sight in Britain1 2 and throughout the world. All too often it is diagnosed only when loss ofthe visual fields is advanced and the condition is resistant to treatment.3 Early detection is therefore of the highest importance, especially with recent evidence that appreciable neur...
متن کاملElectrophysiological approaches for early detection of glaucoma.
PURPOSE While elevated intraocular pressure (IOP) is a major risk factor for glaucoma, only about 1% of patients with 25 mmHg develop the condition each year. Since a sizeable proportion of the ganglion cells are already lost when the visual field losses are apparent, the aim is to identify patients with elevated IOP in whom glaucoma damage is incipient before visual field changes occur. METH...
متن کاملEarly detection of visual field progression in glaucoma: a comparison
Aim—To compare the performance of PROGRESSOR (pointwise linear regression) and STATPAC 2 (comparison with baseline values) in detecting early deterioration in the visual fields of glaucoma patients. Methods—Visual field series from 19 untreated normal tension glaucoma eyes which were deteriorating on clinical grounds were analysed by PROGRESSOR and STATPAC 2. Progression criteria for PROGRESSOR...
متن کاملCommon Molecular Challenges in Glaucoma
95 The clinical entity collectively known as glaucoma is a very specific optic neuropathy that affects individuals with various degrees of ocular complications and even with greater degrees of genetic heterogeneity.[1,2] Although the very first genetic contribution to this group of eye disorders was described over 50 years ago,[3] it took another 30 years before the first molecular studies of t...
