Abstract
Purpose:
To report the current status about the incidence and treatment rate of retinopathy of prematurity(ROP) in Asahikawa medical university.
Methods:
This retrospective study was made on 130 newborn infants with birth weights below 2500 g from2005 to 2011. The series comprised 63 male and 67 female babies. They were born as single birth in 99 cases, as twins in 14 cases, and as triplets in 1.
Results:
The mean birth weight was 1400±453 g, and the mean gestational age was 30.1±2.9 weeks. ROP was present in 34.6% in the whole series. Treatment was performed on 13.8% of cases. In 31 babies with birth weights of 1000 g or less, ROP was present in 80.6% and treatment was performed on 35.5%. There were significant differences in birth weight and gestational age between cases with and without ROP. There were no significant differences in the incidence and treatment rate of ROP between years.
Conclusions:
Incidence and severity of ROP in our hospital were about the same as those reported from other institutions in Japan.
