Gene therapy for wet AMD
Gene therapy is a promising alternative to ongoing eye injections of drugs such as Eyelea, Lucentis and Avastin. The goal of gene therapy is to provide a 'one-and-done' treatment by helping the eye make its own anti-VEGF medicine.
Which is worse dry or wet macular degeneration?
Wet macular degeneration is more serious and is the leading cause of permanent central vision loss. Though the dry type is less serious, it can lead to the wet type if not monitored closely by a doctor.
