Evaluation of Retinal Thickness in Neurodegenerative Diseases using Spectral Domain Optical Coherence Tomography

Introduction: Neurodegenerative diseases are characterised by axonal lesions throughout the central nervous system, including the eye with changes in macular thickness and Retinal Nerve Fiber Layer (RNFL) on histopathologic evaluation. Optical coherence tomography facilitates retina as a surrogate measure of neurodegenerative disease activity. Aim: To evaluate macular thickness and retinal nerve fiber layer thickness in patients with neurodegenerative diseases using spectral domain optical coherence tomography (SD-OCT). Materials and Methods: An analytical observational case control study was carried out over a period of two years. Cases consisted of patients (n=20) with neurodegenerative disorders and controls were age and sex matched ...
