OCT angiography of the choroid in children with spontaneously regressed retinopathy of prematurity and children born preterm

The changes in choroidal thickness (ChT) in children with retinopathy of prematurity (ROP) and those born preterm have recently attracted scientific interest. It has been suggested that together with retina findings, ChT may represent a new biomarker to measure in these eyes since the choroid plays a major role in photoreceptors’ nutrition . ChT has indeed been found reduced in ROP [2, 3, 4]. However, this finding was not replicated in a large population-based study . In the present study, we used OCT angiography (OCTA) imaging to assess the microvasculature in the choriocapillaris layer in spontaneously regressed retinopathy of prematurity (srROP) and in children born preterm (preT) who did not develop ROP, in comparison with an age-matched control group with normal ophthalmologic exam.
We enrolled children born in 2010–2012 and excluded patients with retinal or cardiovascular disease, ocular trauma or surgery, and inadequate cooperation. The study adhered to the...
