Abstract
Retinopathy of prematurity (ROP) is a vasoproliferative disorder of the developing retinal vessels of premature infants. ROP remains one of the leading causes of childhood blindness worldwide. India and other developing countries are facing the third epidemic of ROP. Various risk factors for development of ROP include low gestational age, low birth weight, hyaline membrane disease, sepsis, shock, prolonged oxygen therapy, poor nutrition and weight gain and blood transfusions. Objective: To study nutritional factors and postnatal growth as predictors of ROP in neonates weighing <1750g and/ gestation <34 weeks. Methods: It is a prospective observational study conducted over one year (May 2017 to April 2018) in NICU, Department of Pediatrics, Govt. Medical College Amritsar, in collaboration with Department of Ophthalmology. All antenatal, perinatal and neonatal factors along with nutritional factors and postnatal growth mointoring were recorded. Screening for ROP was done by indirect opthalmoscopy at 4 weeks of postnatal age and followed up till retinal vascularization was complete. Data was analysed using univariate and multivariate regression analysis to evaluate risk factors. Results: Out of 79 babies screened 44 were found to have ROP of which 4 required treatment. Important risk factors found significant on univariate analysis were low birth weight (p=0.023) gestational age (p=0.003), duration of i/v fluid therapy (p=0.004), day of start of feed (p=0.032), day of attainment of full feed (p=0.005), relative weight gain at 4 weeks (p=0.041) and 6 weeks of life (p=0.04). On mutivariate logistic analysis, relative weight gain (g/kg/day) at 4 weeks of life was found to be an independent risk factor. Conclusion: Relative weight gain (g/kg/day) at 4 weeks of life was found to be an independent risk factor for development of ROP. This result may be regarded as providing emphasis on the importance of weight gain at an earlier postnatal age.
