چکیده

Diabetes mellitus patients often suffer from diabetic retinopathy (DRP), a disease that reduces vision significantly. The main cause of this disease is probably hypoxia, lack of oxygen. In this paper a precision analysis of a non-invasive method to calculate the oxygen saturation in the retina in order to diagnose DRP is presented. Simulations show that this approach is promising.

Retinal oximetry in primary open-angle glaucoma.

PURPOSE. To determine whether retinal vessel oxygen saturation is affected in primary open-angle glaucoma (POAG) patients. METHODS. Retinal oxygen saturation in patients with POAG was measured in retinal vessels with a spectrophotometric retinal oximeter in darkness, and visual fields were obtained. Oxygen tension (Po(2)) was calculated from oxygen saturation values. Statistical analysis was pe...

Retinal oximetry measures systemic hypoxia in central nervous system vessels in chronic obstructive pulmonary disease

BACKGROUND Determination of the blood oxyhemoglobin saturation in the retinal vessels of the eye can be achieved through spectrophotometric retinal oximetry which provides access to the state of oxyhemoglobin saturation in the central nervous system circulation. The purpose of this study was to test the capability of the Oxymap T1 oximeter to detect systemic hypoxemia and the effect of suppleme...

Retinal Vascular Response to Breathing Increased Carbon Dioxide and Oxygen Concentrations.

The retina has a high rate of oxygen consumption, and the retinal vessels are knoion to constrict with increased arterial oxygen tension and dilate ivhen arterial oxygen falls. In 10 subjects, measurement of retinal venous oxygen saturation by a photographic technique has shown an increase from 55 ± 8 per cent saturation breathing air to 82 ± 9 per cent breathing 100 per cent Os. This increase ...
