Retrospective evaluation of ophthalmological and neurological outcomes for infants born before 24 weeks gestational age in a Swedish cohort.

Objectives: To retrospectively evaluate ophthalmological and neurological outcomes in a Swedish cohort of infants born before 24 weeks gestational age (GA) and explore risk factors for visual impairment.

Setting: Eye and paediatric clinics in Sweden.

Participants: Infants screened for retinopathy of prematurity (ROP) (n=399), born before 24 weeks GA, 2007-2018.

High rate and large intercentre variability in retreatment of retinopathy of prematurity in infants born <24 gestational weeks.

Objective: Prematurity is a major risk factor for retinopathy of prematurity (ROP). We aimed to elucidate ROP prevalence, treatment and retreatment in infants born before 24 gestational age (GA) weeks in a Swedish cohort.

Methods And Analysis: Infants with completed ROP screening, born at <24 GA weeks, 2007-2018 in Sweden were included.

New modifications of Swedish ROP guidelines based on 10-year data from the SWEDROP register.

Background/aims: During the last decade, improved neonatal care has resulted in increased survival of the most immature infants and improved health of more mature infants. We hypothesise that this has affected incidence and treatment of retinopathy of prematurity (ROP), enabling guidelines for screening to be modified.

Methods: In Sweden, all infants with gestational age (GA) at birth ≤30 weeks are screened for ROP.
