The flowchart illustrates the dataset preparation steps. Dataset 1 comprised of the previously collected database of 483 eyes.8 Dataset 1 prime (n = 1313) was generated by triplicating Dataset 1. The pneumatic retinopexy (PR) success-to-failure ratio was approximately 2-to-1 in Datasets 1 and 1 prime. Dataset 1 was further augmented to generate Datasets 2 (n = 660) and 3 (n = 1313) with a 1:1 PR outcome ratio. The test set was independently collected at the University of California, Davis (UCD) and was not included in the training phase.
