Retinopathy of prematurity (ROP) remains a major cause of childhood blindness. Its pooled prevalence worldwide is 31.9%, and that of severe ROP is 7.5% among prematurely born babies. Investigating risk factors is essential for improving early detection and treatment outcomes. Purpose: To determine the frequency and stages of ROP cases and evaluate the treatment methods for premature infants at the Medical University of Vienna. Methods: In this retrospective study, 352 children who underwent ROP screening between 2018 and 2021 with a gestational age (GA) ≤ 32 weeks and/or a birth weight (BW) ≤ 1500 g were included. Results: ROP was found in 144 (40.9%) of the 352 screened premature infants, with 17 (4.8%) requiring treatment. Significant risk factors included GA and BW, while sex and pregnancy type were not significant. The mean GA was 27.7 ± 2.5 weeks, and the mean BW was 989.1 ± 359.7 g. Infants with ROP had a lower GA (25.9 ± 1.7 weeks) and BW (778.6 ± 262.4 g) than those without ROP (28.9 ± 2.2 weeks; 1134.9 ± 345.9 g). GA and BW were significantly lower in infants developing ROP (p < 0.001). Stage 2 ROP was the most common severity in 74 children (51.4%). Laser therapy was the most common first-line treatment, used in 11 infants (64.7%), followed by anti-VEGF therapy, used in 6 infants (35.3%). Children were treated within 1.0 ± 0.6 days on average. Of the 17 infants treated, 14 (82.4%) showed initial regression. Three infants (17.6%) required re-treatment: two with initial anti-VEGF therapy and one after laser therapy. Conclusions: The findings provide insights into ROP’s prevalence and treatment preferences at a university tertiary care center. GA and BW were confirmed to be significant predictors, aiding in early detection and informing treatment decisions. These insights will enable comparisons with similar studies and contribute to improved patient care.
