This study aims to compare the accuracy of IOP measurements in pediatric patients using two different tonometers: ICare PRO and Corvis ST (CST). However, the choice of tonometers may vary between screening centers, depending on patient suitability. To address this, we enrolled 30 patients with retinopathy of prematurity over a period of 33 days for experimentation. A head-to-head comparison revealed a strong correlation between the Corvis ST (CST) and ICare PRO tonometers (r = 0.867). Furthermore, no significant difference was observed in IOP values obtained with the Corvis ST (CST) and ICare PRO tonometers (P > 0.05). However, it is worth noting that the Corvis ST (CST) measurements were significantly higher than those obtained from the ICare PRO tonometers (P < 0.05). In conclusion, this study demonstrates that the Corvis ST (CST) tonometer exhibits a high correlation coefficient comparable to that of the ICare PRO tonometer, making it a reliable tool for assessing IOP in pediatric patients. These findings are crucial for enhancing our understanding of the physiological function of melatonin in the eye and its potential to target melatonin receptors and their complexes for addressing various eye pathologies.
