Retinal Imaging Study of Children That Might be at Risk of Having Retinal Hemorrhages

The prospective study will take place at university hospitals in three Swedish regions, Stockholm, Skåne and Västra Götaland. The data collection from the three regions will proceed in parallel over a three-year period. An estimated number of children will be 400-500 per year. The study children will be consecutively referred to the pediatric ophthalmology units, where the ophthalmological examinations will take place. Bedside examinations will be performed when indicated at the pediatric intensive care units. Retinal fundus examination will be performed according to clinical standards following administration of pupil dilating eye drops in each eye. Visual function will be evaluated if ophthalmic abnormalities are detected. Prospective observational study Group 1: All infants ≤ 18 months of age, who undergo neuroradiological examinations of the brain on the indication increased head circumference. Group 2: All critically ill children \< 15 years of age, cared for at the hospitals, with neurological symptoms, that require neuroradiological examination of the brain. Group 3: All children ≤ 2 years of age, who undergo emergency neuroradiological examinations of the head at the hospitals.
