The oxygen saturation in retinal vessels can be studied by dual wavelength oximetry, which is based on the analysis of fundus photographs obtained at two different wavelengths. In a recent study using this technique, it was shown that the oxygen saturation in preretinal neovascularizations is arterial, which suggests that these new vessels are shunts that allow the blood to bypass an occluded vascular bed peripheral from the neovascularizations. Therefore, there is a need to investigate how preretinal neovascularizations differ from vascular abnormalities with an established role as vascular shunts in the diabetic retina, such as IRMAs developing from the capillary bed, and omega loops and reduplications developing from larger venules. It is likely that an evaluation of metabolic markers, such as the oxygen saturation in the blood perfusing these vascular abnormalities, may contribute to a deeper understanding of their role in the pathophysiology of diabetic retinopathy.
