BACKGROUND: @entity989 ( @entity989 ) is a cause of neurosensorial morbidity. OBJECTIVES: To study the incidence, associated risks factors, treatment, and outcome of @entity989 in premature @entity1 born at less than 32 weeks in our hospital. METHODS: We performed a descriptive study of @entity1 born between the January 1, 1995, and December 31, 2001, in Sant Joan de D  u Hospital in Barcelona (Spain) at <= 32 weeks of gestation who survived until their first month of life. An ocular evaluation was performed between weeks 4 and 6 of life and was repeated every 1-2 weeks until retinal vascularization was complete. Ocular sequelae and visual function were evaluated. Bivariate comparison of groups with and without @entity989 was performed. RESULTS: Of the 324 @entity1 evaluated, 74 presented @entity989 (22.8 %), of which 63 @entity1 (21.7 %) were classified as stage 1 or 2 and 11 (3.7 %) as stage 3. An inverse correlation between the incidence of @entity989 and weight and gestational age was found. Threshold disease (3 plus) was detected in 9 @entity1 (16 eyes; 3.1 % of the study sample and 12.1 % of the neonates with @entity989 ). All of these neonates were treated with laser therapy. Ocular sequelae were mild in 2.7 % of the @entity1 , moderate in 0.6 % and severe in 0.6 %. The visual function (n 236) of @entity1 with @entity989 (n 74) was altered in 4 @entity1 (1.7 %). Of these, alterations were severe in 2 @entity1 (0.8 %). Bivariate analysis revealed significant differences (p < 0.001) in low birth weight, gestational age, days of @entity26 therapy, days of mechanical ventilation, days of antibiotic therapy, and number of blood transfusions. CONCLUSIONS: In this study the incidence of @entity989 was similar to that in other centers. Development of @entity989 was strongly associated with its various risk factors. Severe stages were not seen above 30 weeks of gestational age. The results of laser therapy were optimal, with fewer alterations in ocular examination and visual function than those estimated in @entity1 without treatment.
