Corneal endothelial cell images
Conditions
Interventions
Gold Standard:1.Corneal endothelial cell density: At the age of 20, the cell density should be greater than 3000, while at the age of 60, the cell density is approximately between 2400 and 2700. If th
Index test:The degree of cell distortion XV=S/Sth * Dmax/Dmin, where S is the area of a single cell, Sth is the critical area of decompensated cell square threshold, and the critical area of decompens

Inclusion criteria
Inclusion criteria: Corneal endothelial cell images taken from patients diagnosed with corneal endothelial dysfunction, macrovesicular keratopathy, Fuchs' corneal endothelial dystrophy, and conical cornea in the outpatient clinic were selected, as well as images of corneal endothelial cells in the above patients after penetrating keratotransplantation. Corneal endothelial cell images were also collected from the normal population.
Exclusion criteria
Exclusion criteria: 1. Images of corneal endothelial cells from other diseases; 2. Poor quality images caused by halo, defocus, and darkness are excluded due to difficulty in image recognition.
