BioSight Tissue Repository and Service Center

A Duke University School of Medicine Service Center and Repository

History, Mission and Partners 


The BioSight shared resource is a product and vision of the late, R. Rand Allingham, MD., the Richard and Kit Barkhouser Distinguished Professor and former Chief of the Glaucoma Service for Duke Eye Center.  The Eye and Tissue Biorepository and Donor Registry of the Duke Eye Center was first established in July 2016, because of the tireless efforts of Cecile Santiago-Turla, MD. The biorepository was named BioSight in July 2018, when it became a shared resource and joined the Duke University School of Medicine Core Research Facilities.  In 2020, its name changed to BioSight Service Center and Repository to align with new Duke naming policies.

Our mission is to effectively evaluate, fairly distribute and securely store the highest quality human ocular tissue possible for the Duke research community.

As a shared resource, we maximize the use of precious, well-characterized ocular tissues to support world-class eye research. Our streamline procurement protocols improve the freshness and number of eyes available for research; and our immediate access to electronic medical records improves tissue value.

Our program is made possible with the strong ongoing partnerships with Duke Health Systems (DHS), Donate Life North Carolina, Carolina Donor Services (CDS) and Miracles in Sight (MiS). Our eye registry for donation is conducted through Donate Life North Carolina website, which manages donor registrations for the state of North Carolina.  Carolina Donor Services (CDS) is the federally designated organ procurement organization for North Carolina, whose core purpose is ensuring that gifts of donation are fulfilled. CDS also works diligently to increase awareness of the need for organ and tissue donation.  CDS partners directly with DHS (Hospitals and Hospice) and MiS to coordinate timely procurement of the eye tissue. A local MiS recovery specialist plays a critical role in directly providing BioSight with the donated eyes from Duke Hospitals.

Together we are all moving forward to advance eye research.




We provide characterized ocular tissue for research

  • Fresh eye globes
  • Ocular tissue Processing and Storage
  • Training and Consultation
  • Protocol Support and Development
  • Consenting for Surgical Tissue Discard
  • Extract relevant medical history from EMR (de-identified)
procurement process


If you are interested in obtaining samples or collaborating, please contact:

We can discuss your study-specific needs, as well as help you process your request.

Postmortem ocular tissues can be provided as whole globes, half globes, or tissue sections. 

Available fresh (without preservative) within a specified death to preservation time, or preserved following your specific research protocol.

De-identified clinical and ophthalmic information is associated with most of the samples provided regulatory requirements are met to receive human samples with de-identified data.
