Abstract (in Japanese) (See Japanese page) 
(in English) Keratoconus is one of an ophthalmic disease on a cornea, which brings thinning and deformation in the center of cornea and causes high myopia or astigmatism. Anterior segment optical coherence tomography (Anterior Segment OCT) is used to diagnose keratoconus including its stage. We applied machine learning to analyze images by anterior segment OCT. A resulted trained model, based on convolutional neural network, classified eyes of normal and grade 1 to 4 in Amsler-Krumeich classification with 85.3% accuracy. It also classified normal eyes and keratoconus eyes with 99.6% accuracy.
