Automatic retinal oximetry.
PURPOSE To measure hemoglobin oxygen saturation (SO(2)) in retinal vessels and to test the reproducibility and sensitivity of an automatic spectrophotometric oximeter. METHODS Specialized software automatically identifies the retinal blood vessels on fundus images, which are obtained with four different wavelengths of light. The software calculates optical density ratios (ODRs) for each vesse...
متن کاملConscious sedation and pulse oximetry: false alarms?
The use of pulse oximetry in dental procedures involving sedation and children has been encouraged strongly. Reports have indicated that hemoglobin desaturations are not uncommon when a variety of drugs (including nitrous oxide) and dosages are used. The present study investigated the nature of desaturations in relation to patient activity as a function of a drug combination, single drug dose-r...

متن کاملRetinal Oximetry Discovers Novel Biomarkers in Retinal and Brain Diseases.
Purpose Biomarkers for several eye and brain diseases are reviewed, where retinal oximetry may help confirm diagnosis or measure severity of disease. These include diabetic retinopathy, central retinal vein occlusion (CRVO), retinitis pigmentosa, glaucoma, and Alzheimer's disease. Methods Retinal oximetry is based on spectrophotometric fundus imaging and measures oxygen saturation in retinal ...
متن کاملRetinal Oximetry in a Healthy Japanese Population
PURPOSE To establish the normative database of retinal oximetry using Oxymap T1 in a healthy Japanese population, and study the reproducibility of the measurements in Japanese. METHODS We measured oxygen saturation in the major retinal vessels with Oxymap T1 in 252 eyes of 252 healthy Japanese subjects. Fundus images acquired using Oxymap T1 were processed using built-in Oxymap Analyzer softw...
