Resumen:
Objective. Retinopathy of prematurity (RoP) is a retinal vascular disease and a frequent cause of blindness in infants. Our objective was to measure the frequency of RoP in infants with extremely low birth weight (ELBW, < 1,000 g) at the National Institute of Perinatology, Neonatal Intensive Care Unit (NICU), weighing the association of RoP with several risk factors and their results, such as refractive errors and strabismus. Material and methods. We carried out two cross-sectional observations of our prospective study: one near birth, and the second, after a long-term follow-up. Funduscopic examination was performed while the infants were in the NICU to detect RoP. Infants with RoP were followed up by means of visual examinations during an average 8-year period and results were compared with those of infants with ELBW without RoP. Results. Of the 139 screened infants at the NICU, 24.4% were identified with RoP: 79% of these with grade I retinopathy; 18% with grade II, and one infant w
