Retinoblastoma is a childhood eye cancer, which usually occurs before the age of three. The cause is almost always genetic - and results from defects in a gene called RB1.
These defects can be identified through genetic sequencing of DNA taken from retinoblastoma patients' blood and/or tumours. Currently, the only way to analyse tumour DNA is by removing the eye, so affected children have to go under general anaesthetic.
Dr Amy Gerrish at Birmingham University is working on a test that will allow researchers to identify Rb in patients who have not had their eye removed.
In this webinar, she will spotlight her research, leading to better childhood cancer diagnosis. Dr Gerrish will be joined by Fight for Sight's Ambassador, Katie Elliott, who aged four was diagnosed with retinoblastoma.
