Ocular Physiology Clinical Trial
Official title:
Short Term and Day to Day Reproducibility of Reflectometric Measurement of Retinal Oxygen Saturation in Healthy Subjects
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.
