Training software of a new app that spots abnormal 'white eye' reflection in photographs
Taking photos with a flash often leads to 'red eye' – bright light reflecting off the retina leaves pictured faces with red pupils. This is actually a healthy sign of clear eyes – with the flash doing a similar job to a doctor’s ophthalmoscope. With many more photos taken during early childhood than routine eye exams, a new app called CRADLE (also called White Eye Detector) can help parents to scan through photos of their children, spotting any unusual 'white eye' reflections – known as leukocoria – that may need checking by a doctor. This set of leukocoric pupils on the left, and healthy ones on the right, from children under three years old, were used to train the software to spot tell-tale signs – potentially leading to earlier diagnosis of conditions that obstruct the eye, like childhood cataracts or amblyopia.
