Abstract:Wet age-related macular degeneration is a severe and blinding disease with progressive central visual impairment, accounting for about 10%-15% of age-related macular degeneration.

However, this treatment mode requires frequent intraocular injection, and many patients must continue to use it indefinitely to preserve their vision. Gene therapy can provide long-term stable anti-VEGF activity, which has become a new hotspot of research. Several methods of gene therapy are summarized as follows.
