Background: Retinopathy of prematurity (ROP) is the leading cause of blindness among prematurely born children. The incidence of any stage of ROP in children born before the 31st gestational week in Europe and the USA is between 10-45%. The purpose of this study was to show characteristics of ROP between 2015 and 2019 at the Neonatal Intensive Care Unit of the University Medical Centre Ljubljana (NICU-Lj), which is the larger of the two tertiary referral centres in Slovenia and in which more than two thirds of Slovenian very low birth weight children are treated. Methods: All prematurely born children screened for ROP at NICU-Lj between 2015 and 2019 were included in the study. The following parameters were recorded: number of children screened, total number of exams, number of exams per child, number of children with ROP, ROP stages, number of children who needed ROP treatment and number of treatments per child treated. Results: Between 2015 and 2019, 82-130 prematurely born children fulfilled ROP screening criteria each year. A total of 1,412 exams were performed over the period of five years (range: 239-386 per year). Every child had one or more ROP screening exams (range: 1-10). Extremely preterm children born before the 27th week of gestation had more exams (average: 5 exams/child) compared to other prematurely born children (average: 1.5 exams/child). The number of prematurely born children with any stage of ROP ranged from 17 to 30 per year. ROP of any stage was present in 18.75% (2015), in 17.7% (2016), in 23% (2017), in 29.3% (2018), and in 24.1% (2019). More than 70% of all babies with ROP were born before the 27th gestational week. The most mature baby with ROP was born with 29 6/7 weeks of gestational age. Every year, 15-35% of babies with ROP received laser treatment. Conclusions: ROP is an important disease in prematurely born children. During the period 2015-2019, the incidence of any stage of ROP and of serious ROP requiring treatment was comparable. The screening and treatment of ROP requires intense cooperation between paediatric ophthalmologists and neonatologists in order to prevent blindness in prematurely born children.
