Epidemiology and treatment trends of retinopathy of prematurity: a multi-center study involving four Asian centers and one European center (2016-2023).

Demographics varied significantly (p <0.001); India had the highest gestational age and birth weight, and the lowest proportion of very low birth weight and extremely low birth weight infants with type 1 retinopathy of prematurity (p <0.001).

Hong Kong had the lowest retinopathy of prematurity incidence, while Singapore showed a significant increase over time (p = 0.003).

Type 1 retinopathy of prematurity rates were higher in Taiwan and India than in Hong Kong and Singapore, with a significant decline observed only in Taiwan (p = 0.005).
