Fundus imaging in newborn children with wide-field scanning laser ophthalmoscope

Abstract

Purpose: Current fundus imaging in newborn babies requires mydriatics, eye specula and corneal contact. We propose that a scanning laser ophthalmoscope (SLO) allows ultra wide-field imaging with reduced stress for the child. Methods: This prospective observational single centre study was conducted in Landspítali, University Hospital, Reykjavik, Iceland. In this study, a noncontact wide-field SLO (Optomap 200Tx) was used to image the retina in healthy full-term newborns without the use of mydriatics or eye specula. The child was held by one of the parents, while one of the researchers supported the child's head in front of the SLO camera for alignment and opened the eye with either a finger or a cotton tip. Results: Fifty-nine participants were recruited (34 females). The mean age was 16 days, and the mean gestational age was 40 ± 1 weeks at the time of imaging. Ultra-wide-field (200°) images were obtained of 44 participants. Twenty-seven participants (61%) had at least one ultra wide-field image with the optic disc and vessel segments in all quadrants of the fundus visible and in focus. No retinal pathology was found in the participants with the exception of one participant with small retinal haemorrhages. Conclusion: Scanning laser ophthalmoscope (SLO) ultra-wide-field fundus imaging is feasible in healthy full-term newborns without corneal contact, eye speculum or mydriatics. This approach could be an improvement for retinal imaging in newborn infants. Eye movement of the infant, whether asleep or awake, influenced which part of the fundus was captured, but focus and image quality were generally good.
