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).

ABSTRACT:

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 years.

Methods

All 462 children born EPT in Sweden during April 2004-March 2007, and surviving to age 6.5 years, and full-term born matched controls were invited to participate in the 12-year follow-up. VA was assessed at 12 years and the results were compared with values at 2.5 and 6.5 years.

Results

At age 12, 332 (72%) EPT survivors and 189 controls were examined. The mean
