Maternal diabetes mellitus as an independent risk factor for clinically significant retinopathy of prematurity severity in neonates less than 1500g.

BackgroundRetinopathy of prematurity (ROP) is a significant morbidity in preterm babies. Multiple risk factors for severe ROP have been extensively studied, however, only a few studies have included maternal diabetes mellitus (MDM) in their assessment. ROP and diabetic retinopathy are both retinal vascular diseases in which there is leakage and/or neovascularization from damaged retinal vessels. Diabetes may affect ROP development; however, there are conflicting results on the association between MDM and ROP.ObjectiveTo determine if MDM is an independent risk factor for clinically significant ROP (ROP > Stage II) in neonates weighing less than 1500g.Design/methodWe conducted a retrospective cohort study of neonates weighing ResultsWe extracted 883 paired maternal-neonatal data. The mean (standard deviation) gestational age and birthweight were 28.5 (2.9) weeks and 1052.7 (300.9) grams, respectively. Of the 883 mothers, 72 (8.2%) had DM. The incidence of ROP and severe ROP was 42.4% (374/883) and 6.5% (57/883) respectively. The odds ratio comparing MDM and severe ROP was 3.47 [95% CI: 1.51-7.96]; pConclusionMaternal diabetes is associated with ROP and the strength of association increased with increasing severity of ROP
