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.

• corn_pro: CORN Pro: Corneal Nerve Confocal Microscopy Dataset (component_dataset)

Documented relationships

These links record source-supported lineage or overlap, not merely similar modality tags.

• corn1500 is component of this record: CORN-1500 is a named component of the combined CORN collection. (evidence)
• corn_pro is component of this record: CORN-Pro is a named component of the combined CORN collection. (evidence)
• This record is has component corn1500: The CORN collection lists CORN-1500 as one of its six component deposits. (evidence)
• This record is has component corn_pro: The CORN collection lists CORN-Pro as one of its six component deposits. (evidence)

Access information and download

CLI

# This route requires upstream human action; no transfer starts.
eyehub download corn_collection --data-dir ./data --dry-run --json
# Follow the official instructions shown by preflight.

Python

from eyedatahub.acquisition import preflight_dataset
from eyedatahub.datasets.registry import REGISTRY

ds = REGISTRY.get_dataset('corn_collection')
print(preflight_dataset(ds, './data'))  # returns manual_access_blocked
