Abstract
BACKGROUND: Retinopathy of prematurity (ROP) is a preventable cause of childhood blindness. Without treatment, over 45% of eyes can develop permanent visual loss. Hyperglycaemia has recently been described as a risk factor for the development of retinopathy of prematurity (ROP), a proliferative vascular disease of the retina that primarily affects premature infants. The characteristic neoproliferative growth of blood vessels in the retina is very well under stood with the clinical and experimental experiences with Diabetic retinopathy. The purpose of this study was to evaluate a possible relation between glucose levels in VLBW (Very Low Birth Weight) infants and development of ROP. METHOD: All at risk infants of a Neonatal Intensive Care Unit (NICU) of a tertiary care centre in western India were included in the study. The blood sugar values of the neonates were recorded at multiple times during their first week of life. On completion of 31 weeks of gestational age or 04 weeks of birth age, the neonates were subjected to ROP screening as per standard protocols. RESULT: A total of 103 neonates were included in the study and were subjected to ROP screening. A total of 32 neonates developed ROP at the end of the study. It was found with statistical significance that the neonates with higher average blood glucose values in the initial period of life had higher incidence of ROP at the time of screening with a Relative Risk of 2.506 (CI = 1.287, 4.882). CONCLUSION: A high average blood glucose level in neonates during the first week of life is an indicator for developing ROP at a later date. These neonates should be kept under close follow up in order to facilitate timely detection and prompt intervention.
