Norwich and Norfolk University Hospital (NNHU) have unveiled a new research study to help combat blindness in the region.

Twenty-five patients are signed up to the 'STAR study' which received a surge of interest following the ophthalmology unit's new machine, the IRay, which was unveiled in May.

The machine is a non-invasive robotic radiotherapy, used to treat patients with wet age-related macular degeneration (AMD).

Heidi Cate, ophthalmology research unit manager, said: 'We are the only trust in the east of England to have the machine and patients had to travel down to London before.'

'AMD affects the central vision and patients affected are desperate to hold on to it.'

Two-thirds of patients taking part in the study will receive an active treatment, with the remaining participants undergoing a placebo.
