Dataset Summary

Harvard-FairSeg is a large-scale ophthalmology dataset for studying fairness in medical image segmentation. It contains 10,000 SLO fundus images with pixel-wise optic disc and cup segmentation masks, paired with comprehensive demographic annotations. The dataset is designed to benchmark and improve demographic equity in segmentation models, including foundation models such as SAM (Segment Anything Model).

This dataset was introduced at ICLR 2024: FairSeg: A Large-Scale Medical Image Segmentation Dataset for Fairness Learning Using Segment Anything Model with Fair Error-Bound Scaling.

Data Fields

Each subject is stored as a .npz file (data_00001.npz … data_10000.npz) containing:

Field	Description
`slo_fundus`	Scanning Laser Ophthalmoscopy (SLO) fundus image
`disc_cup_mask`	Pixel-wise optic disc and cup segmentation mask
`age`	Patient age
`gender`	`0` = Female, `1` = Male
`race`	`0` = Asian, `1` = Black, `2` = White
`ethnicity`	`0` = Non-Hispanic, `1` = Hispanic, `-1` = Unknown
`language`	`0` = English, `1` = Spanish, `2` = Other, `-1` = Unknown
`maritalstatus`	`0` = Married/Partnered, `1` = Single, `2` = Divorced, `3` = Widowed, `4` = Legally Separated, `-1` = Unknown

A metadata overview is provided in data_summary.csv under the ReadMe folder.

Demographics

6 demographic attributes are annotated per patient: age, gender, race, ethnicity, preferred language, and marital status.

Uses

Direct Use

Fairness benchmarking for medical image segmentation models, including evaluation of demographic disparities in optic disc and cup segmentation. Intended for use with segmentation architectures such as SAMed and TransUNet.

Out-of-Scope Use

Clinical decisions, patient care, or any commercial application. This dataset shall not be used for clinical decisions at any time.
