Methods We conducted a retrospective cohort study of preterm infants screened in 2021 at the University Medical Centre Ljubljana, Slovenia. The G-ROP criteria were systematically applied. Primary outcomes were sensitivity for ROP requiring treatment, sensitivity for any ROP, and reduction in the number of infants screened. Results Of 102 infants screened, 27 (26.4%) developed ROP. Eleven infants (10.7%) had type 1 ROP, of whom 2 (1.9%) had aggressive ROP; 5 infants (4.9%) had type 2 ROP, and 11 (10.7%) had milder ROP. Using the original or simplified G-ROP criteria, all infants who developed type 1 ROP (sensitivity, 100% [95% CI, 74%-100%]), and all infants who developed ROP (sensitivity, 100% [95% CI, 88%-100%]) were correctly identified. Application of the original G-ROP criteria would have reduced the number of infants screened by 29.4% (30 of 102). Conclusions In our cohort, both the original and simplified G-ROP criteria showed 100% sensitivity for predicting ROP type 1 while reducing the number of unnecessary screenings. These results confirm the reliability of the G-ROP criteria in the Slovenian context and suggest that their use improves screening efficiency.20252025-03-05 13:25:18Članek v reviji167660sl
