Short Term and Day to Day Reproducibility of Reflectometric Measurement of Retinal Oxygen Saturation in Healthy Subjects

NCT00991900 · Status: WITHDRAWN · Type: OBSERVATIONAL

Last updated 2018-06-11

No results posted yet for this study

Summary

Adequate perfusion and oxygenation is essential for the function of the inner retina. Although this is a well known fact, measurement of oxygen saturation in the eye is still a delicate and not fully explored task. However, recently a new instrument for the non-invasive measurement of retinal vessel oxygen saturation has been introduced. Unfortunately, no data about reproducibility in humans is yet available for this instrument. Consequently, the current study seeks to evaluate the short term and day to day reproducibility of retinal vessel oxygenation in healthy volunteers.

20 healthy volunteers will be included and oxygen saturation of retinal vessels will be determined. The reproducibility of the results will be tested by repeated measurements and the collected data will be independently analyzed by two observers.
