Objective: We aimed to investigate if hyperglycemia is a risk factor of retinopathy of prematurity (ROP) in very low birth weight (VLBW) infants.
Methods: One hundred forty-seven VLBW infants during the years 2011 through 2015 were included in this retrospective study. Glucose levels were analyzed with whole blood for three weeks after birth. Hyperglycemia was defined as the blood glucose level over 125 mg/dL. ROP patients were compared with non-ROP patients. Variables significantly related to ROP including glycemic characteristics were evaluated in a multivariate analysis.
Results: ROP occurrence was associated with perinatal factors like birth weight (BW), gestational age, 5-minute Apgar score and premature rupture of membranes. It was also significantly related to neonatal factors like respiratory distress, surfactant use, bronchopulmonary dysplasia, congenital heart disease, transfusion, surgical operation, apnea, aminophylline or caffeine use, ventilator days, and admission days. In glycemic characteristics, hyperglycemia duration, average and maximum glucose level for 3 weeks after birth showed statistical significance. But, in a multivariate analysis, only BW and surfactant use were independently associated with ROP, while glycemic characteristics were not. In comparisons based on ROP severity, hyperglycemia duration, average blood glucose level of 3rd week after birth, and insulin use showed significant difference, but they were not independent factors.
Conclusion: In this study, hyperglycemia duration, average and maximum blood glucose level during three weeks after birth were statistically significant, but they were not independent factors associated with ROP development.
