Insights
Diode laser photocoagulation effectively treated type 1 prethreshold retinopathy of prematurity (ROP) in premature infants. This safe and efficient treatment resulted in a 99.1% regression rate with no severe complications.
Area of Science:
- Ophthalmology
- Neonatology
- Medical Technology
Background:
- Retinopathy of prematurity (ROP) is a significant cause of visual impairment in premature infants.
- Type 1 prethreshold ROP requires timely intervention to prevent severe visual outcomes.
- Diode laser photocoagulation is a common treatment modality for ROP.
Purpose of the Study:
- To evaluate the efficacy and safety of diode laser photocoagulation for type 1 prethreshold ROP.
- To assess treatment outcomes in premature infants at Peking University People's Hospital.
Main Methods:
- Retrospective cross-sectional study.
- Review of clinical records of premature infants treated for type 1 prethreshold ROP between 2008 and 2012.
- Analysis of treatment outcomes, including regression rates and complications.
Main Results:
- 226 premature infants (146 male, 80 female) were included.
- Mean birth weight: 1386 grams; mean gestational age: 30.2 weeks.
- 99.1% of treated eyes (381/384) showed complete ROP regression; no severe complications were observed.
Conclusions:
- Diode laser photocoagulation is a safe and efficient treatment for type 1 prethreshold ROP.
- The treatment demonstrated a high success rate with minimal adverse events.
- Further research can explore long-term visual outcomes.
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.
