Abstract:
Objective:To explore the necessity, construction plans, and implementation methods for the establishment of a fundus disease-specific biobank are discussed.Methods:An evidence-based medicine study. "Biobank", "Disease-specific biobank", "Eye diseases", "Fundus disease" were hereby used as search terms. Literatures were retrieved related to biobank construction from PubMed, Embase, China National Knowledge Infrastructure, and Wanfang databases since their establishment until October 2023. Two researchers independently selected and analyzed literature, extracting data for further analysis.Results:After screening, 23 articles were included, comprising 11 articles in Chinese and 12 articles in English, involving 23 institutions. The disease-specific biobank has been built earlier abroad than domestically. Both domestic and foreign biobank have a scale of less than 1, 1 to 10, and more than 10 thousand samples, with the eye disease-specific biobank having less than 10 thousand samples. The majority of these disease-specific biobank focued on tumor-related diseases and consist of both physical and information components. Ethical committees were required to declare and record the construction of biobank, and dedicated personnel and information management systems are established. Quality control systems have been developed with standard operating procedures from sample collection to storage. These disease-specific biobank effectively supported research projects, but there was a lack of resource sharing domestically compared to abroad. Based on practical experience, the construction of fundus disease-specific biobank at West China Hospital of Sichuan University has been improved. Separate sample collection processes have been formulated for outpatient clinics and operating rooms. Standard operating procedures have been established for unique eye samples, including vitreous fluid, proliferative membranes of the retina, aqueous humor, tears, etc., to ensure sample quality.Conclusion:Establishing a fundus disease-specific biobank can promote basic and clinical research, advance the development of translational medicine, achieve resource sharing, and foster discipline development.
