PURPOSE: To determine the frequency of retinopathy of prematurity at the Clinical Hospital of Ribeirão Preto Medical School (HCFMRP-USP) and verify the association of retinopathy of prematurity with known risk factors. METHODS: Prospective analysis of 70 patients born in the HCFMRP-USP, weighing less than 1,500 grams, in a period of 1 year. The patients were divided into 2 groups (Retinopathy of prematurity and Normal) to verify the association of retinopathy of prematurity and known risk factors. Significance level of 5% was used. RESULTS: The frequency of retinopathy of prematurity was 35.71% among the study population. The studied risk factors significantly related to the development of the disease were: weight (p=0.001), gestational age (p=0.001), score SNAPPE II (p=0.008), use of oxygen by intubation (p=0.019) and continuous positive airway pressure (p=0.0017), multiple blood transfusions (p=0.01), and the use of diuretics (p=0.01). CONCLUSION: The frequency of retinopathy of prematurity was 35.71% and several risk factors have been identified in newborns in the HCFMRP-USP, being evidenced that the more preterm, the more severe retinopathy of prematurity is likely to be.
