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.

The purpose of the study is to test if oxygen saturation in retinal vessels is correlated with clinical parameters, such as visual acuity, central retinal thickness and presence of neovasc...
The inner retina is crucially dependent on an adequate retinal blood supply. When the retina becomes ischemic and hypoxic this results in severe vision loss due to retinal neovascularizati...
The purpose is to investigate how the adenosine affects the diameter regulation of retinal arterioles during changes in oxygen tension. A deeper understanding of the mechanisms involved in...
An adequate oxygenation and retinal perfusion is essential for the function of the inner retina. There is a wide range of autoregulation mechanisms to ensure a sufficient ocular blood and ...
Dual wavelength retinal oximetry allows the quantification of oxygen saturation in the larger retinal vessels. However, the technique might be refined further by identifying factors that are responsib...
Visible-light optical coherence tomography (vis-OCT) enables retinal oximetry by measuring the oxygen saturation of hemoglobin (sO) from within individual retinal blood vessels. The sO calculation req...
Introduction The evaluation of retinal vessels and the retinal blood flow is important for ocular diseases. We introduce a spectral domain optical coherence tomography (SD-OCT) based method for facili...

A group of rare, idiopathic, congenital retinal vascular anomalies affecting the retinal capillaries. It is characterized by dilation and tortuosity of retinal vessels and formation of multiple aneurysms, with different degrees of leakage and exudates emanating from the blood vessels.
Measurement of the blood pressure of the retinal vessels. It is used also for the determination of the near point of convergence (CONVERGENCE, OCULAR). (From Cline, et al., Dictionary of Visual Science, 4th ed)
The determination of oxygen-hemoglobin saturation of blood either by withdrawing a sample and passing it through a classical photoelectric oximeter or by electrodes attached to some translucent part of the body like finger, earlobe, or skin fold. It includes non-invasive oxygen monitoring by pulse oximetry.
Formation of new blood vessels originating from the retinal veins and extending along the inner (vitreal) surface of the retina.
The blood vessels which supply and drain the RETINA.
