[Retinopathy of prematurity. The results after a 1-year follow-up].

OBJECTIVE

To analyze prospectively the incidence and outcome of retinopathy of prematurity (ROP) in preterm infants admitted to a neonatal intensive care unit.

PATIENTS AND METHODS

A high risk group of infants with birth weights less than 1,500 g, and/or a gestational age less than 30 weeks, was studied. Ophthalmoscopic examination was performed at six weeks of age. Frequent ophthalmoscopic examinations were then performed depending on the gravity of the ROP.

RESULTS

ROP was found in 14 of the 20 preterm infants (70%). Two developed stage 3 and none of them stage 4 or 5. Cryotherapy for ROP was not used. None of the infants progressed to advanced stages of ROP and complete resolution was the rule.

CONCLUSION

Despite the low incidence of advanced stages of ROP in our study, we suggest that all preterm infants less than 1,500 g and/or 30 weeks of gestational age, should be screened for ROP and repeated ophthalmoscopic examination performed in order to evaluate the progression and treatment of ROP.
