RESUMO
PURPOSE: To identify and compare the profile of retinopathy of prematurity (ROP) in premature babies in urban and semiurban neonatal intensive care units (NICUs). METHODS: A prospective study of babies admitted to NICUs of two urban and seven semiurban centres. They were <36 weeks of gestational age and were subjected to fundus photography with a RetCam shuttle camera. Photos and NICU details were uploaded on a secure website. Photographs were read by a single observer. Infants were followed till retinal vascularisation was complete, or 45 weeks post conceptional age. Babies developing severe ROP were lasered. RESULTS: 500 babies were screened (243, urban group; 257, semiurban group). Incidence of ROP in the urban and semiurban groups was 16.5% (40) and 14.8% (38) respectively. Mean gestational age was 30.90 weeks and 31.53 weeks respectively. Mean birth weight was 1344 g and 1375 g respectively. 28 babies were lasered, 15 and 13 from each group respectively. There was no statistically significant difference between any of the parameters compared. Level of significance was fixed at 0.05. CONCLUSIONS: The magnitude of the burden of ROP is comparable between urban and semiurban NICUs stressing the need for effective screening strategies in semiurban and rural areas as well.
