목적 : To evaluate the retinal findings before retinopathy of prematurity (ROP) as prognostic factors
방법 : The authors reviewed the wide-field retinal imaging at 33~34 weeks of postmenstrual age (PMA) from 78 premature infants (< 31 weeks of gestation age) between March 2018 and April 2019. The authors assessed the location of the leading vascular edge location, the committed vascular abnormality ( the retinal edge hemorrhage, circumferential vessels, branching vessels) in immature retina. Analysis was performed to find out the correlation between each variable and the occurrence of any stage ROP.
결과 : Any stage ROP had occurred more in infants with the vascular edge in Zone I or posterior Zone II other than infants with normal retinal vessel formation up to Zone II at 34 weeks of PMA. The probability of developing ROP in preterm babies with the retinal edge hemorrhage was 28.96 times higher. The presence of circumferential vessels, branching vessels of immature retina were more common in preterm infants who developed any stage ROP.
결론 : The retinal findings such as retinal edge hemorrhage, circumferential vessels and branching vessels at PMA 33~34 weeks suggest higher chances to develop ROP than those without theses findings.
