Abstract: BACKGROUND: Due to the lack of effective donor and tissue reconstruction materials, many diseases in the ophthalmology field have unsatisfactory therapeutic effects.
OBJECTIVE: To summarize the sources of acellular materials by referring to the published literature, and analyze acellular material in clinical and basic research of ophthalmology so as to promote the effective application of acellular tissue materials in ophthalmology.
METHODS: The Wanfang database, CNKI database and PubMed database were searched for relevant literature from January 2014 to August 2020 using the keywords “acellular, decellularization” combined with “cornea, conjunctiva, lacrymal gland, lacrymal drainage, trabecular meshwork, retina, sclera, orbit”, separately. A total of 56 articles were eventually included, of which 49 were in English and 7 in Chinese.
RESULTS AND CONCLUSION: (1) There are multiple sources of decellularized tissues currently used in ophthalmology, which can be broadly categorized into three categories: human, animal and acellular matrix after in vitro cell culture. (2) The use of decellularized tissue materials in the reconstruction and repair of ophthalmic diseases can achieve better clinical results and save the vision of some blind people. (3) The acquisition of implants containing active cells through decellularized scaffolds combined with recipient cell transplantation is a new direction for future ophthalmic regenerative medicine treatment. (4) Some deficiencies were found during the application of the decellularized material, such as longer adaptation time, graft sheet dissolution and shrinkage, and incomplete cellularization.
