Abstract

Adeno-associated virus (AAV) vectors have been widely employed in gene therapy for ocular and systemic diseases. However, clinical trial outcomes have indicated that gene therapy may trigger severe adverse events associated with immune-inflammatory reactions, thereby impacting the safety and efficacy of gene therapy. The immune-inflammatory reaction induced after gene therapy in the eye is referred to as gene therapy-associated uveitis, which has become a major obstacle limiting the long-term and effective use of ocular gene therapy. This review comprehensively explores four aspects: the immune response mechanisms of gene therapy, ocular manifestations of associated uveitis, factors influencing immune inflammation, and preventive and therapeutic strategies. The aim is to provide insights for the development of safer and more effective ocular gene therapy.
