Although not now new, gene therapy is an evolving procedure for the treatment of a range of eye conditions. Recent developments include an American-based trial involving a gene editing process known as CRISPR. We speak to Dr Eric Pierce and Dr Mark Pennesi, who were both involved in the trial, as well as Olivia Cook, who tells us about her experience of undergoing the pioneering treatment.

Closer to home, we caught up with Professor Rob Lucas from the University of Manchester. Professor Lucas tells us about developments in gene therapy here in the UK.
