-- Retinopathy of Prematurity (ROP) is a vasoproliferative retinopathy that affects immature infants whose etiology remains unknown. Some studies have suggested an association between early exposure to light and this pathology. A study was done to demonstrate if the ocular occlusion is related to the incidence of retinopathy in premature infants in the Maternal Perinatal Institute. The analytical quasi-experimental study, includes all the premature babies of very low weight (<1301 grams.) and less than 32 weeks, born between January 01, 2005 to December 31, 2007. It was considered to be 201 patients who expired with the criteria of incorporation, they were divided in two groups, one of them whom became occlusion both eyes with mask of black fabric (study) and other one without occlusion exposed to the natural light of the environment (control). Ambos groups, were homogeneous in age, sex, weigh and taken care of nursery. The ROP's incident was compared in both groups presenting some ROP's degree 25 of 97 patients with eyes occluded (25.8 %) and 34 of 104 patients with eyes not occluded (32.7 %). The study determined that it was no relation between ROP's incident of the exposed children or not to the environmental light RR 1.27 IC 95% (0.82-1.96), and there were benefit moderated for the severe degree (degree 2) in the occluded patients RR 0.55 IC 95 % (0.29 - 1.04). It concludes that the occlusion does not diminish the incident to develop retinopathies in born premature babies of very low weight but it has protective effect in severe cases of this one disease. -- KEY WORDS: Retinopathy of prematurity, ocular occlusion, ambient light.
