Performance of the NDLS in the internal test dataset
(A) Receiver operating characteristic curves (ROCs) of the NDLS for discerning keratitis, other corneal abnormalities, and normal cornea in low-quality images.
(B) ROCs of the NDLS for discerning keratitis, other corneal abnormalities, and normal cornea in high-quality images.
(C) Confusion matrixes of the NDLS in low- and high-quality images. NDLS, new deep learning system. “Others” denotes other corneal abnormalities. “Normal” denotes normal cornea.
