Detecting optic nerve head deformation and retinal nerve fiber layer thinning in glaucoma progression
The application of digital imaging technologies including confocal scanning laser ophthalmoscopy (CSLO), optical coherence tomography (OCT), and scanning laser polarimetry (SLP) has significantly improved the detection of optic nerve head (ONH) deformation and progressive retinal nerve fiber layer (RNFL) thinning for assessment of glaucoma progression. Algorithms for change analysis such as top...
متن کاملAge-associated changes in the retinal nerve fiber layer and optic nerve head.
PURPOSE Optical coherence tomography (OCT) measures of the retinal nerve fiber layer (RNFL) thickness and neuroretinal rim (NRR) parameters are often used as a surrogate for retinal ganglion cell content. The purpose of this study was to investigate the relationship between these morphological measures and the aging effects on these structures. METHODS One hundred thirteen healthy individuals...
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 کاملOptic nerve head topographic measurements and retinal nerve fiber layer thickness in physiologic large cups.
PURPOSE To evaluate the parameters of optic nerve head (ONH) and retinal nerve fiber layer (RNFL) in patients with large cup/disc ratio (CDR) and normal neuroretinal rim configuration who have normal perimetry (physiologic large cups, LC) and to compare these parameters with those of the normal and early glaucoma patients. METHODS Using Heidelberg retinal tomography (HRT) and optical coherenc...
متن کاملRetinal Nerve Fiber Layer Thicknesses in Three Different Optic Nerve Head Size
Although the assessment of peripapillary retinal nerve ber layer (RNFL) thickness is essential in the diagnosis and management of glaucoma, its objective evaluation remains a challenge in clinical practice.1 Quantitative measurements of RNFL thickness have become possible with the development of imaging technologies such as optical coherence tomography (OCT). Several authors have shown that the...
