Retinal 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...
متن کاملRetinal blood flow in healthy young subjects.
PURPOSE To characterize total retinal blood flow in a group of healthy subjects. METHODS Included in this study were 64 healthy volunteers. Retinal venous diameters were measured using a dynamic vessel analyzer. Retinal blood velocities were measured using bidirectional laser Doppler velocimetry. All vessels with a diameter of >60 μm entering the optic nerve head were measured. Total retinal ...
متن کاملAutomatic 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 کاملInfluenza vaccine efficacy in young, healthy adults.
Findings concerning influenza vaccine efficacy in young, healthy adults are inconsistent. A high incidence of influenza in the winter of 1995 provided an opportunity to study the efficacy of influenza vaccine among young, healthy military personnel. Influenza activity was confirmed by isolation of influenza A and B viruses from nasopharyngeal swab specimens from hospitalized soldiers. Self-admi...
متن کاملSystolic murmurs in 525 healthy young adults.
Much has been written by physicians about patients referred to them because of the discovery of a systolic murmur. Inevitably such consultant physicians have scant opportunity to judge the incidence, character, and significance of murmurs among apparently healthy people. Freeman and Levine (1933) described the systolic murmurs that they had found in a group they had examined of a thousand perso...
