Retinopathy of prematurity: progress report
1Department of Neonatology, Children's Hospital National Medical Center, Washington, DC 20010.
Insights
The risk of retinopathy of prematurity (ROP) is linked to the survival of premature infants. Stabilizing their environment and specific treatments can reduce ROP incidence and severity.
Area of Science:
- Neonatal ophthalmology
- Perinatal medicine
Background:
- Retinopathy of prematurity (ROP) is a significant risk for extremely low birth weight premature infants.
- The developing retinas of these infants are exposed to abnormal and fluctuating environments.
Purpose of the Study:
- To outline current strategies for reducing ROP risk and severity.
- To discuss potential future treatments for ROP.
Main Methods:
- Review of current clinical practices for managing premature infants.
- Discussion of established and emerging therapeutic interventions for ROP.
Main Results:
- Stabilizing ventilation, oxygenation, and perfusion can decrease ROP incidence and severity.
- Moderating light exposure and providing vitamin E are beneficial.
- Cryotherapy can arrest the progression of stage 3 ROP.
Conclusions:
- Current management focuses on environmental stabilization and timely intervention.
- Future research may yield pharmacologic agents like antioxidants to improve safety margins.
- Regular eye examinations and specialized ophthalmologic care are crucial for affected premature infants.
Abstract:
For the time being, risk of ROP seems inexorably linked to survival of extremely low birth weight prematures, whose embryonic retinas develop in an abnormal and fluctuating environment. Incidence and severity may be reduced by stabilizing ventilation, oxygenation, and perfusion, moderating light exposure, and providing normal levels of vitamin E. Progression of stage 3 retinopathy may sometimes be arrested by cryotherapy. In the future, antioxidants or other pharmacologic agents may be developed to provide a greater margin of safety. In the meantime, the eyes of prematures must be examined and those with ROP will need specialized ophthalmologic care.
