Inclusion criteria
Inclusion criteria: 1.Patients who visited or were hospitalized in the Corneal Disease Specialty Group 101 or the Cornea and Ocular Surface Disease Center of the Eye Hospital of Wenzhou Medical University between January 1, 2013 and May 1, 2026. 2.Patients who underwent at least one slit-lamp anterior segment photography or anterior segment photography examination during previous clinical care. 3.Availability of corresponding demographic information, visit information, diagnostic information, or relevant medical record text. 4.Anterior segment structures are sufficiently visible in the images for sign recognition and annotation.
Exclusion criteria
Exclusion criteria: 1.Images with severe defocus, markedly abnormal exposure, or major obstruction of the observation area by eyelids, instruments, or other factors, making evaluation of key anterior segment signs impossible. 2.Corrupted or unreadable image files, or images that cannot be effectively linked to key information such as patient identity, laterality, or visit time. 3.Missing key clinical records that prevent necessary data verification or label construction. 4.Duplicate images or images clearly irrelevant to the study purpose. 5.Other data considered unsuitable for model training or evaluation after quality control by the research team.
