Biobanks: collections of eye disease biological samples
Biobank’s eye disease samples inventory
Biobanks (also known as biological resource centers) are entities responsible for the management of biological samples and their associated data.
These structures can collect and preserve biological samples of eye disease in the form of samples inventory.
Eye diseases represent all the pathologies affecting the components of the eye and the vision. They may be due to infections, genetics or aging, and may cause vision disorders such as a decrease in visual acuity, blurred vision, double vision or distorted vision.
Microorganisms (bacteria, fungi, viruses) that can infect the eye may induce eye infections such as conjunctivitis and keratitis. Some eye diseases are more common with age, such as glaucoma and cataracts, while others are age-related, such as presbyopia and age-related macular degeneration (AMD).
Biobanks collect and store biological samples from patients with eye diseases. Some samples are made available for research: nucleic acid extractions, tissue blocks and organs, etc.

Setting up a collection of biological samples
After a biopsy, or other procedure to retrieve a human sample, a sample may be retained, with the patient's consent, for research purposes.
How is a eye disease collection request made?
Collecting, receiving and sending eye disease samples are regulated activities and must be declared and/or subject to authorization. The biobank or biological resource center assists external applicants in the structuring of their project and their administrative procedures.
Setting up a biological collection
The first step in setting up a sample collection is to identify the partner(s) with both access to patients with the disease of interest, and also the technical capacity to collect the type of biological samples required.
Biobanks will typically be able to respond individually to certain requests, and collectively to requests that require expertise or resources not available to them. This is particularly the case for specialized biobanks such as tumor banks, cell banks, serum banks, etc.
Since these are collections of biological samples from patients, the request must be motivated, clear, and included in a proposal that can be shared with the biobank. The required information generally relates to the nature of the project in which the biological collection is to be built up, the number and types of clinical samples desired, the processing and preparation of the samples for analysis, etc. The information should be provided in a clear and concise manner.
The biobank can decide for or against the setting up of the project; the files are submitted to a scientific committee, which must give its approval before proceeding with the project. If the project continues, a feasibility study is carried out to determine whether the biobank has the technical capacity for the application. A financial estimate, as well as the drafting of a contract is carried out by the biobank in order to finalize the agreement between the parties. Finally, the biobank puts in place the internal operating procedure for collection, reception, storage and preparation of the biological resources until they are taken over.
Access a pre-existing collection - availability
Retroactive sample release is a transfer of biological material to another organization (public or private) as part of a joint research program (research partnership). This partnership must be formalized by a research collaboration agreement or contract that defines the framework of the joint research between the partners and the use that will be made of the biological resources. Applications must also be motivated and included in a project, which will be submitted to a scientific committee or to the clinical manager of the biological collection for validation. These requests may concern tumor or non-cancerous samples, as well as blood cells in the case of regular requests.
Types of providers
There are two major categories of biological resource centers:
University hospital structures
The majority of biobanks and BRCs are attached to a public hospital organization, which give them access to clinical physicians and allow them for biological collections from patients.
Some private service companies may provide collections built up in the course of in-house projects or organize sample collections for clinical projects.
These two types of service providers differ from their public or private nature and their degree of specialization in a certain type of biological resources: cell bank, tumor bank, serum bank, etc.
Automatic DNA and RNA extractors
Conservation cold environment: freezers -20°C, -80°C and tank Liquid nitrogen -180°C
Computer system for managing anonymized data
Estimated rates for this type of service
Setting up a collection: €5,000 to €15,000
The price of a biological sample depends on the preparation required (slide, fresh, nucleic acid extracts), the original organ, the desired quantity and the clinical information associated with the patient; and can vary from approximately €200 to €2,000.
