Retinal nerve fiber layer reflectance for early glaucoma diagnosis.
PURPOSE Compare performance of normalized reflectance index (NRI) and retinal nerve fiber layer thickness (RNFLT) parameters determined from optical coherence tomography (OCT) images for glaucoma and glaucoma suspect diagnosis. METHODS Seventy-five eyes from 71 human subjects were studied: 33 controls, 24 glaucomatous, and 18 glaucoma-suspects. RNFLT and NRI maps were measured using 2 custom-...
متن کاملOptic Nerve Head and Retinal Nerve Fiber Layer Imaging in Glaucoma Diagnosis
Glaucoma is a chronic, progressive neurodegenerative disease. It is defined as chronic progressive optic neuropathy with typical optic disk and retinal nerve fiber layer (RNFL) changes with corresponding visual field defect. Intraocular pressure (IOP) is considered only a major risk factor and not a diagnostic criterion. At present, clinically visible RNFL defects are considered as the sensitiv...
متن کاملRetinal nerve fiber layer loss in glaucoma patients with a relative afferent pupillary defect.
PURPOSE To assess the amount of structural loss (retinal nerve fiber layer [RNFL] thickness loss, macular thickness [MT] and volume [MV] measured by optical coherence tomography [OCT]) and functional loss (visual acuity [VA], visual field mean deviation [MD], brightness sensitivity, and red perception) necessary for a relative afferent pupillary defect (RAPD) to manifest in patients with glauco...
متن کاملCan Automated Imaging for Optic Disc and Retinal Nerve Fiber Layer Analysis Aid Glaucoma Detection?
PURPOSE To compare the diagnostic performance of automated imaging for glaucoma. DESIGN Prospective, direct comparison study. PARTICIPANTS Adults with suspected glaucoma or ocular hypertension referred to hospital eye services in the United Kingdom. METHODS We evaluated 4 automated imaging test algorithms: the Heidelberg Retinal Tomography (HRT; Heidelberg Engineering, Heidelberg, Germany...
متن کاملRetinal nerve fiber layer defect and cerebral small vessel disease.
PURPOSE To determine whether retinal nerve fiber layer defect (RNFLD) is associated with cerebral small vessel diseases (SVDs) and to identify risk factors for RNFLD. METHODS A total of 4421 Korean subjects who underwent health checkups including brain magnetic resonance imaging (MRI) and fundus photography between January 2008 and October 2009 were included in this study. Co-morbid systemic ...
