Purpose: To describe the foveal morphology of pre- term infants with and without retinopathy of prema- turity (ROP)
Method: Retrospective review of charts of preterm infants who were imaged with bedside handheld spectral-domain optical coherence tomography (OCT) (Envisu, Bioptigen, Inc., Research Triangle Park, NC) at the Royal Children’s Hospital, Mel- bourne, Victoria between February 2018 and May 2018. Electronic medical records were accessed; ges- tational age, birth weight, presence of and severity of ROP was recorded. Digital wide field images (RetCam 3, Clarity Medical Systems, Inc., Pleasan- ton, CA) and bedside handheld spectral-domain OCT of the fovea were collated and reviewed.
Results: Records and images of 12 preterm infants were reviewed. These comprised of preterm infants with varying grades of ROP. Foveal morphology was correlated with demographic data and ROP grade. Cystoid macular oedema is a common finding in these infants. Inner and outer retinal layer thick- ness contribute to the foveal morphology being vastly different from that of adults.
Conclusion: Foveal morphology in preterm infants changes rapidly with growth. ROP seems to influ- ence foveal development. Cystoid macular oedema is a common finding in preterm infants.
