FERNANDEZ RAGI, Rosa María et al. Incidence of the retinopathy of prematurity in the low birthweight. Rev Cubana Oftalmol [online]. 2010, vol.23, suppl.1, pp. 580-589. ISSN 1561-3070.

OBJECTIVE: To find out the situation of the retinopathy in children with birthweight under 1750 grams or born with less than 35 weeks in Havana province. METHODS: A prospective longitudinal study of all the low birthweight children in Havana province, who were born from January from 2004 to December of 2008, was made. A total number of 1847 low weighted children was obtained. The study protocol included those children who were born weighing less than 1750 grams or whose gestational age was lower than 35 weeks; their risk factors were taken into consideration. The deceased children in this period were excluded. RESULTS: The incidence was 15.3 % based on the ophthalmologic exam. It was higher in the grade III, in the 1000-1499 gram range of weight and in the age 28-32 wk gestational age. In the studied children, the highest percentage had received oxygen therapy except for two cases. CONCLUSION: Despite the low incidence of retinopathy of prematurity, this disorder is severe in grade III, in the 1000-1499 gram weight and the 28-32 week gestational age; the oxygen therapy is a very important risk factor.
