CORN: Corneal Confocal Microscope Dataset Collection
Combined corneal confocal microscopy collection comprising CORN-1, CORN-2, CORN-3, CORN-1500, CORN-Pro, and CORN-Complex. The subsets support corneal-nerve and cell segmentation, image enhancement, tortuosity grading, and multi-disease analysis.

Counts retain their source-reported units. Additional rows can describe components, paired items, or derivative copies and are not automatically added to the primary quantity.
Notes
The Zenodo record is publicly visible, but its files require a logged-in access request containing the user's name, organization, work, and intended use. EyeDataHub displays those instructions and does not submit the request. This collection includes and overlaps the separately indexed CORN-1500 and CORN-Pro records; its six subsets must not be counted as independent cohorts.
Dataset family
This record belongs to corn_collection. Family links group documented collection/component records or exact task views; they do not imply independent cohorts.
