[The efficiency of 810 nm diode laser photocoagulation for type1 retinopathy of prematurity].

OBJECTIVE

To evaluate diode laser photocoagulation effects in type 1 prethreshold retinopathy of prematurity (ROP) in Peking University People's Hospital.

METHODS

Retrospective cross-sectional study. Clinical records of the premature infants treated for type 1 prethreshold ROP from the year of 2008 to 2012 were reviewed.

RESULTS

We reviewed 226 infants including 146 male and 80 female. The mean birth weight and the gestational age were 1 386 grams and 30.2 weeks respectively. In all the 384 photocoagulation treated eyes, ROP regressed completely in 381 eyes (99.1%). One eye of zone I ROP progressed to stage 4A. Macula kept attaching after vitrectomy. There was no significant difference of regression rate between Zone I and Zone II of type 1 prethreshold ROP. No severe complications occurred.

CONCLUSIONS

Diode laser photocoagulation in type 1 ROP was safe and efficient.
