Background and aims Retinopathy of prematurity (ROP) is still a worldwide leading cause of childhood blindness. We aimed to describe the visual outcome at 5 years in a cohort of preterms diagnosed of ROP.
Method We analysed the data based of preterm infants ≤32 weeks and/or ≤1500g born between January2002 and December2008 with the diagnosis of ROP who were followed up. Visual outcome was evaluated at 5 years using visual acuity (impaired <0.8), strabismus and refractive errors (myopia <-3D or hypermetropia >3D).
Results 71 patients were followed-up (mean age 27weeks and mean weight 951g). 64.8% had moderate ROP (MROP), 15,5% not treated severe ROP (ROP-NT) and 19,7% severe ROP treated with laser (ROP-Laser). At the age of 5 years, 21.1% weared glasses, 14,1% had the diagnosis of refractive errors (1 myopia and 9 hypermetropia). Only one patient, with moderate ROP had strabismus. We did not find differences in the visual prognosis according to the severity of ROP. (Table1)
Conclusions In our cohort, patients with severe ROP (treated or not) do not have a worse visual prognosis at five years than those with moderate ROP. These findings are probably related to the gestational age of the study population.
