This book was released on 2015-05-14 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical coherence tomography (OCT) provides tissue morphology imagery at much higher resolution than other imaging modalities such as MRI or ultrasound, and the machines are comparatively cheaper. It is an easy technique to perform; is non-ionizing, and therefore safe. These benefits are driving a rapid transformation of OCT, from its principal application as a research tool, into an extension of the 'neurological examination' in routine office practice. Originally used in assessing the severity of tissue damage and prognosis of multiple sclerosis and various neuro-ophthalmic conditions, OCT is increasingly used in other neurological disorders such as Parkinson's disease, ALS, and Alzheimer's disease. This book is the first comprehensive review of the use of OCT in neurological diseases. The coverage includes a description of the technique and its utilization in a variety of neurologic conditions. Essential reading for neurologists, neuro-ophthalmologists, and neuroradiologists wanting an introductory account of the clinical applications of OCT.

Book excerpt: The second edition of OCT and Imaging in Central Nervous System Diseases offers updated state-of-the-art advances using optical coherence tomography (OCT) regrading neuronal loss within the retina. Detailed information on the OCT imaging and interpretation is provided for the evaluation of disease progression in numerous neurodegenerative disorders and as a biological marker of neuroaxonal injury. Covering disorders like multiple sclerosis, Parkinson's disease, Alzheimer's disease, intracranial hypertension, Friedreich's ataxia, schizophrenia, hereditary optic neuropathies, glaucoma, and amblyopia, readers will given insights into effects on the retina and the and optic nerve. Individual chapters are also devoted to OCT technique, new OCT technology in neuro-ophthalmology, OCT and pharmacological treatment, and the use of OCT in animal models. Similar to the first edition, this book is an excellent and richly illustrated reference for diagnosis of many retinal diseases and monitoring of surgical and medical treatment. OCT allows to study vision from of the retina to the optic tracts. Retinal axons in the retinal nerve fiber layer (RNFL) are non-myelinated until they penetrate the lamina cribrosa. Hence, the RNFL is an ideal structure for visualization of any process of neurodegeneration, neuroprotection, or regeneration. By documenting the ability of OCT to provide key information on CNS diseases, this book illustrates convincingly that the eye is indeed the "window to the brain".

Book excerpt: Multiple sclerosis (MS) is a chronic disease of the central nervous system (CNS) affecting more than two million people worldwide. The disease is characterised by inflammation in the CNS (leading to episodes of focal neurological dysfunction, i.e. relapses) and neurodegeneration (leading to progressive and permanent disability). Depending on the localisation of the CNS damage, patients exhibit a wide range of symptoms including muscle weakness, sensory disturbances, problems with coordination, fatigue and cognitive impairment. Visual symptoms are common as well, with more dan 50% of MS patients experiencing one or more episodes of optic neuritis (ON) during the course of the disease. The disease course in MS is highly variable and difficult to predict. However, predicting the disease course is crucial for determining the proper treatment. This thesis focuses on how optical coherence tomography (OCT) can aid in monitoring and predicting the disease course in patients with MS. OCT is an imaging technique that generates high resolution images of the retina and all its layers. The inner two retinal layers consist of the retinal ganglion cells and their axons that will eventually form the optic nerve. Thereby, these two layers are directly connected to the brain. Previous research has demonstrated that previous episodes of ON result in atrophy (thinning) of these two layers. Sometimes, it can be challenging to establish whether a patient has ever experienced an episode of optic neuritis clinically. The absolute thickness of the retinal layers is not a good indicator for this. Our research shows that the difference in retinal layer thickness between the eyes of a single patient can, with high accuracy, discriminate ON patients from non-ON patients. Being able to establish the presence of a previous episode of ON in this way, might lead to an earlier diagnosis of MS and earlier treatment.

Download or read book Optical Coherence Tomography in Neurodegenerative Disorders written by Hannah Maree Kersten and published by . This book was released on 2016 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: Purpose Ophthalmic findings, including abnormalities of the optic nerve and retina, are common features of a number of neurodegenerative disorders. These ophthalmic abnormalities have emerged as potential biomarkers of disease progression in several neurodegenerative conditions. In addition, anterior visual system changes have clinical relevance because they can be a significant cause of disability. Optical coherence tomography (OCT) allows for rapid, non-invasive imaging and quantitative analysis of the optic nerve and retina. Over the past 15 years, OCT has been widely used to investigate axonal and neuronal degeneration in the eye, and the relationship with disease severity in multiple sclerosis, neuromyelitis optica Alzheimer's disease and Parkinson's disease. OCT is now frequently utilised in observational studies, clinical practice and therapeutic trials of potential neuroprotective agents. The objectives of the studies outlined in this research thesis were twofold: Firstly, to investigate the morphology of the optic nerve head and retina, using OCT, in patients with neurodegenerative disorders, and to determine the relationship between OCT measurements and disease duration and severity. Methods Subjects with neurodegenerative disorders including muscular dystrophies, Huntington's disease, Parkinson's disease, motor neuron disease, ataxias and hereditary spastic paraplegia were recruited. All participants underwent a complete neuro-ophthalmic assessment including retinal photography and OCT examination of the peripapillary retinal nerve fibre layer (RNFL) and macula. Ophthalmic findings were compared with those from a healthy control group. Additionally, neurological assessment was undertaken in order to be able to assess the relationship between OCT findings and disease severity. Results OCT examination was performed in patients with a diverse range of neurodegenerative disorders. There was preferential thinning of the temporal RNFL in the Huntington's disease and cerebellar ataxia neuropathy vestibular areflexia syndrome (CANVAS) cohorts. Global RNFL thickness was reduced in the Friedreich's ataxia and hereditary spastic paraplegia (HSP) groups. In the myotonic dystrophy type 1 (DM1), Parkinson's disease, motor neuron disease and facioscapulohumeral muscular dystrophy (FSHD) groups, there was no significant difference in RNFL thickness between patients and controls. Macular thickness was greater in the myotonic dystrophy type 1 group compared with controls. This was due to a high prevalence of epiretinal membrane, detected with OCT examination. Macular volume was significantly reduced in the Freidreich's ataxia patient group. There was no significant difference in macular thickness or volume between patients and controls in the Parkinson's disease, motor neuron disease, Huntington's disease, CANVAS, FSHD or HSP groups. In the Huntington's disease group there was a significant correlation between disease duration and both temporal RNFL thickness and macular volume, and a significant relationship between motor assessment scores and macular volume. There was no significant relationship between symptom duration, measures of disability and/or cognitive function and OCT findings in the DM1, Parkinson's disease, motor neuron disease, CANVAS, HSP, Friedreich's ataxia or FSHD groups. Conclusions OCT measurements may be potential biomarkers of disease progression in Huntington's disease patients. The preferential thinning of the temporal RNFL in Huntington's disease may be due to mitochondrial dysfunction. In addition, OCT assessment has a role in the clinical assessment of patients with myotonic dystrophy, in the detection and monitoring of patients with epiretinal membranes. Larger, longitudinal studies are required in order to determine the relationship between ophthalmic and neurological findings in neurodegenerative disorders, and to further investigate the utility of OCT measurements as potential biomarkers of disease progression in these conditions.
