We are walking across London at night for the Childhood Eye Cancer Trust to raise money for retinoblastoma research.

Asa was diagnosed with retinoblastoma in January 2012. Since then he's received many different treatments, but still the struggle against the disease continues.

For details of the excellent research that the Childhood Eye Cancer Trust supports, see here.
