This dataset of size and shape measurements of 354,998 human corneal endothelial cells, from 2000 routine assessment images, from a sequential series of 678 corneas from 351 donors, was collected with consent by the New Zealand National Eye Bank over several years, after organ-culture storage but prior to release for transplantation. The measurement methodology using Voronoi segmentation is detailed in:Brookes NH. Morphometry of organ-cultured corneal endothelium using Voronoi segmentation.
