Drs. de Boer gave a presentation on oxygen saturation of the retinal blood vessels at the 10th congress of the European Academy of Neurology (EAN). Her research shows that the oxygen saturation of RVCL-S patients is higher in the veins of the retina compared to healthy controls. The difference in oxygen saturation between arteries and veins was smaller in RVCL-S patients. This teaches us more about how retinopathy in RVCL-S can develop.
