Research summary
Wet age-related macular degeneration is the most common cause of blind registration in the UK. Standard treatment involves regular eye injections of a drug called ranibizumab (Lucentis). For most patients, ranibizumab maintains their vision but the effect of the drug is temporary, and they therefore require monthly hospital visits and typically six injections into the eye every year, probably for life. This study tests a new surgical device that delivers a focal dose of radiation (epimacular brachytherapy) to the macula (the part inside the back of the eye that gives fine central vision), to try and reduce or eliminate the need for ongoing, regular eye injections. The trial compares epimacular brachytherapy to ongoing standard treatment with ranibizumab. Whereas most studies of this new surgical device target patients who have not yet commenced any treatment, this study targets those who are requiring frequent eye injections, as there are limited surgical resources and these resources are best directed to those who have not fully responded to ranibizumab therapy, or whose response is shortlived. These patients have the most to gain from a device that may reduce their burden of treatment. The findings in untreated disease cannot be extrapolated to this discrete subset of patients, hence the need for a study that targets refractory disease.
