Abstract: Recently, the researches on retinal oxygen metabolism in myopia mainly focuses on retinal oxygen saturation and retinal blood flow. The studies of retinal oxygen saturation have now been limited to measurement of oxygen saturation in the large retinal vessels. Most studies have found retinal vessel diameter was reduced in myopic eyes. Retinal blood flow in myopic eyes decreased, foveal and peripapillary capillary density decreased, and foveal avascular area increased. There was a positive correlation between blood oxygen saturation and axial length in myopic children and adolescents. However, arterial and venous oxygen saturation difference in highly myopic adults was less than in emmetropia adults. (Int Rev Ophthalmol, 2022, 46:  346-350)

Key words: myopia, retinal blood flow, retinal oxygen saturation
