Eyes tests are peformed on all babies born at less than 30 weeks of age, or weighing under 1.5 kilograms at birth.
Premature babies are at an increased risk of a condition called Retinopathy of Prematurity (ROP) which is linked to high oxygen saturation levels in babies receiving oxygen therapy. This is why we attempt to keep babies' 'sats' roughly within a set range.
An eye doctor (opthalmologist) will examine the retina at the back of a baby's eyes to check that they are normal. This test may need to be repeated after a week or two.
