The dismutation of O 2 . results in the formation of hydrogen peroxide (H 2 O 2 ), which can lead to elevated levels of other potentially harmful reactive oxygen and nitrogen species (ROS, RNS) 2
Tear volume, as measured by the Schirmer test, remained unchanged, indicating that symptom relief was driven primarily by improved film quality rather than augmented aqueous production
Unlike the atmospheric oxygen tension typically encountered in vitro (approximately 21% O 2 ), the oxygen tension in vivo is markedly lower, often decreasing to 3% or even less, especially in injured tissues (Wang et al., 2022), migration (Yang et al., 2019), and angiogenesis (Zhu et al., 2014)
