Techniques for subretinal injections in animals

open access: yesVeterinary Ophthalmology, Volume 28, Issue 2, Page 506-518, March 2025.
Abstract Subretinal injections are not commonly performed during clinical treatment of animals but are frequently used in laboratory animal models to assess therapeutic efficacy and safety of gene and cell therapy products. Veterinary ophthalmologists are often employed to perform the injections in the laboratory animal setting, due to knowledge of ...
