The purpose of this study was to assess unique corneal tomographic parameters of allergic eye disease (AED) using optical coherence tomography (OCT) and artificial intelligence (AI). A total of 57 eyes diagnosed with AED were included. The curvature and aberrations of the air-epithelium (A-E) and epithelium-Bowman's layer (E-B) interfaces were calculated. Random forest AI models were built combing this data with the parameters of healthy, forme fruste keratoconus (FFKC) and KC eyes. The AI models were cross-validated with 3-fold random sampling. Each model was limited to 10 trees. The AI model incorporating both A-E and E-B parameters provided the best classification of AED eyes (area under the curve=0.958, sensitivity=80.7%, specificity=98.5%, precision=88.2%). Further, the E-B interface parameters provided the highest information gain in the AI model. A few AED eyes (n=9) had tomography parameters similar to FFKC and KC eyes and may be at risk of progression to KC. This article is protected by copyright. All rights reserved.
