OBJECTIVES: The objective is to predict the development of retinopathy of prematurity (ROP) in discordant twins using a machine learning approach.
METHODS: The records of 640 twin pairs born at 32–35 weeks gestational age (GA) with birth weight (BW) discordance were evaluated retrospectively. The infants’ gender, GA, postmenstruel age at examination, BW, discordance rate, ROP Stages and Zones, and treatment options were recorded. The variables were used to develop a model to predict the development of ROP. Machine learning models were used for algorithm training and 10-fold cross-validation (CV) was applied for validation. The main measures were reported as sensitivity, specificity, receiver operating characteristic curve, and the area under the curve.
RESULTS: A total of 640 twin pairs underwent ophthalmic examination, of which 55 (4.3%) were ROP. The infants’ GA was 33.56±1.01 weeks (32–35 weeks) and BW was 1996±335 g (1000–3400 g). The mean discordance rate of the infants was 11.8±9.7% (0.0–53.9%). Using operating points, the Decision Tree algorithm detected ROP prediction with 71% sensitivity and 80% specificity in CV, while the Multi-Layer Perceptron algorithm detected 70% sensitivity and specificity. In addition, the X-Tree and Random Forest algorithms detected ROP prediction with 84% and 80% specificity, respectively.
DISCUSSION AND CONCLUSION: The results of this study support that BW discordance may be effective in the development of ROP in preterm twins and that artificial intelligence models can predict the development of ROP in accordance with clinical findings.
