Objetive: To determine the incidence of intraretinal hemorrhage in newborns of the Hospital de San Jose from September 2009 to September 2010. Design: Cohort study Methodology: Live newborns were examined at the Hospital de San Jose for a year (September 2009 to 2010), analizyng neonatal and maternal factors associated with the presence of intraretinal hemorrhage. A simple ramdon cluster sampling was used, excluding neborns with a compromised general status, as well as those whose parents or legal guardians did not sign the informed consent form. Patients with the presence of intraretinal hemorrhages were examined every 2 weeks until resolution was observed. Results: A total of 190 newborns were examined, finding an incidence of intraretinal hemorrahages of 22.6% (95% CI 16.6 to 28.6). Most of the mothers werw nulliparous (55.8%) and deliveries were eutocic (65.1%). From newborns with hemorrhages, 81.3% were born al term, and hemorrhages in most patients (93.0%) were resolved by the second week of monitoring. Asociations between hemorrhages and cesarean section (RR 0.42, CI 0.22 to 0.79) and episiotomy (RR 1.73, CI 1.02 to 2.94) were observed. Conclusions: Newborns who presented intraretinal hemorrhages werw childen of nulliparous mothers on whom episiotomy was performed, and some with eutocic and instrumented deliveries. The first two variables had statistical significance for the development of intraretinal hemorrhages.
