A UNIVERSITY of Southampton eye expert is leading research using state-of-the art imaging to predict which patients with early age-related-macular-degeneration (AMD) are at more risk of blindness.

Andrew Lotery, professor of ophthalmology in the University’s Faculty of Medicine and Institute for Life Sciences member, heads an international research team which has received nearly £4m funding from the Wellcome Trust to explore what makes early AMD progress towards visual loss.

The innovative study brings together experts in ophthalmology, genetics, statistics and computer science to collaborate on the project.

AMD is a very common cause of blindness with 200 million people expected to be affected by 2020, increasing to nearly 300 million by 2040.

It is a complex, inherited, and diverse disease that affects the macula - the central retina that is responsible for detailed central vision.

Doctors currently don’t know who will develop the sight-threatening stage of the disease; some patients progress slowly, or not at all, while others quickly deteriorate.

The five-year research project will teach computers to analyse high resolution images of the inside of the eye to identify what eye changes appear in patients with AMD and identify the structural changes that lead to and are associated with cell degeneration in the retina in patients with early AMD.

Andrew, who is also a consultant ophthalmologist at Southampton General Hospital’s eye unit, says: "Our research aims to pinpoint what makes AMD progress towards visual loss, and enable us to better predict which patients will progress to the late stages of the disease.

"By understanding more about these markers and why AMD develops, we will be able to better inform patients, clinicians and researchers on prevention, screening, and individualised treatment strategies.

"Ultimately it will help us make sure patients are in the right place - with some in the community and those who need specialised treatment in hospital – and will also help us manage capacity better.

"We will be able to run clinical trials more effectively and thus allow faster development of new treatments.

"We expect the research to give us new insights into how the disease develops and new treatments will result from this."
