Management of retinopathy of prematurity (ROP) in a Polish cohort of infants.

Retinopathy of prematurity (ROP) is potentially blinding, but screening and timely treatment can stop its progression. The data on treatment outcomes of ROP from Central and Eastern Europe are scarce. Therefore, we aimed to analyze the latest results of ROP management in Poznan medical center to update the data from this world region. In the years 2016-2019, 178 patients (350 eyes) received treatment for ROP (6.1% of the screened population). The mean gestational age was 26 weeks (range 22-31 weeks), the mean birth weight was 868 g (range 410-1890 g). The most frequent ROP stage at treatment was zone II, stage 3 + (34.9%). As the first line of treatment, 115 infants (226 eyes, 64.6%) underwent laser photocoagulation (LP); 61 infants (120 eyes, 34.3%) received intravitreal ranibizumab injections (IVR); and 2 infants (4 eyes, 0.6%) were treated simultaneously with LP and IVR. One hundred twenty-six eyes (36%) of 63 patients required retreatment: 20.4% treated with LP and 66.7% treated with IVR. Retinal detachment occurred in 14 eyes (4%). The incidence of ROP, ROP requiring treatment, and reoccurrence rates are higher in the Polish population than in Western Europe and the USA. The identified treatment patterns find increasing use of anti-VEGF agents.
