People in Ireland are being invited to be screened for free for a condition that can cause sight loss.
They will also be able to join a trial if they are found to have early stages of it.
Anyone of any age can make an appointment to go to the Whitfield Institute of Vision Research in Waterford on Saturday, reports Independent.ie.
They will be tested by the Macular Pigment Research Group at the Waterford Institute of Technology for Age-Related Macular Degeneration (AMD) and can join a free trial if the early signs of the ailment are detected.
The trial, led by Eithne Connolly and Dr John Nolan, includes use of Macushield, a dietary supplement.
Dr Nolan said: "It is hoped the trials will inform healthcare professionals regarding the benefits of nutritional supplements to help thousands more at-risk patients losing their sight."
In February, Independent.ie reported the case of Jimmy Aherne, erstwhile Cork club hurler, who suffered from AMD.
He was initially told he would lose his sight.
But after taking Macushield, the worsening of his sight stopped and his vision has improved in his good eye.
