What is Photodynamic Therapy?
Photodynamic therapy is a form of laser treatment used to treat certain types of wet AMD. It was the first NICE approved treatment for wet AMD and was a breakthrough treatment in the early 2000s.
When is it used?
In practice although it slowed deterioration in vision this was superceded by anti-VEGF injections which showed much better results. Nowadays photodynamic therapy is still used in rare cases of disease types which are not responding or are unlikely to respond to anti-VEGF injections alone.
The main subset of macular degeneration treated in this way is called idiopathic polypoidal choroidal vasculopathy.
Although rare in the UK it is important you are assessed for idiopathic polypoidal choroidal vasculopathy.
This may mean you need a different type of angiogram called ICG. Your doctor will advise you if you need this.
