My research aims to improve the patho-physiological understanding and clinical monitoring of retinal disease and also to evaluate new techniques in a clinical setting to provide sensitive, objective outcome measures of both retinal and systemic disease. The work utilizes state-of-the-art imaging techniques for the non-invasive objective assessment of retinal thickness and retinal capillary, arteriolar and venular hemodynamics, in addition to techniques to assess visual function, in human volunteers. Topics include: Diabetes, diabetic retinopathy and macular edema, age-related macular degeneration, retinal disease, glaucoma, arterio- / athero-sclerosis, systemic diseases with ocular impact Non-invasive imaging of the eye, scanning laser technology, Retinal blood flow assessment, metabolic imaging including retinal oximetry and autofluorescence, hemodynamics, retinal vascular reactivity, endothelial function, nitric oxide, endothelin, vascular tonus, compliance, vascular physiology. Dr. Hudson is an approved Ph.D. supervisor.
