Purpose
To validate the performance of Postnatal Growth and Retinopathy of Prematurity (G-ROP) screening criteria in a Taiwanese cohort.
Design
Screening evaluation with retrospective data.
Method
Premature infants who underwent retinopathy of prematurity (ROP) screening between January 2015 and April 2019 at a tertiary hospital were examined. Infants with known final ROP results and complete longitudinal weight records were included. G-ROP screening criteria, both original and simplified (G-ROP 180 g), were applied as the prediction model for type 1 ROP; sensitivity and specificity were analyzed. The reduction in the number of infants requiring ROP screening and the number of funduscopic examinations were calculated.
Result
A total of 303 infants with documented ROP outcomes and complete weight gain records were examined. Of these, 103 infants developed ROP, of whom 29 developed type 1 ROP, whereas the other 200 did not develop ROP. For the detection of type 1 ROP, the sensitivity and specificity of the original G-ROP screening criteria were 96.6% and 42.3%, and 100% and 31%, for the simplified G-ROP 180 g model, respectively. The reduction in the number of infants requiring screening and funduscopic examinations was 32.6% and 33.5% for the original G-ROP criteria, and 28.1% and 23.2% for the G-ROP 180 g model, respectively.
Conclusion
Both the original G-ROP and G-ROP 180 g criteria attained high sensitivities in detecting type 1 ROP in the current Taiwanese cohort, with the G-ROP 180-g model outperforming the original one. Validation and modification may be required before applying G-ROP screening criteria to different populations.
