Visual acuity outcomes up to 12 years and risk factors for visual impairment in a national cohort of extremely preterm born children – The Extremely Preterm Infants in Sweden Study (EXPRESS)
Purpose: The Extremely Preterm Infants in Sweden Study (EXPRESS) followed a national cohort of extremely preterm born (EPT, i.e. <27 weeks) children until 12 years of age. This study aimed to investigate the longitudinal development of visual acuity (VA) in children born EPT, explore the predictive value of early visual assessments, and evaluate risk factors for visual impairment at the age of 12
