[Premature retinopathy: recommendations for a screening policy]
Insights
Optimal retinopathy of prematurity (ROP) screening requires multiple assessments. Screening between weeks 7-9 offers the best single detection window, but multiple screenings are recommended for comprehensive ROP monitoring and timely treatment.
Area of Science:
- Ophthalmology
- Neonatology
- Public Health
Context:
- Retinopathy of prematurity (ROP) is a significant cause of visual impairment in premature infants.
- Optimal screening strategies are crucial for early detection and intervention.
- Current data on ROP screening effectiveness are limited.
Purpose:
- To evaluate the effectiveness of different screening schedules for retinopathy of prematurity.
- To determine an optimal screening strategy balancing incidence monitoring and therapeutic intervention timing.
- To assess the detection rate of ROP based on single versus multiple screening moments.
Summary:
- A 1-year study analyzed the incidence and course of ROP in premature infants.
- A single screening detects less than 70% of ROP cases; if used, it should occur between weeks 7-9.
- Multiple screenings (weeks 4-5, 8, and 11) likely provide the best approach for ROP management and incidence approximation.
Impact:
- Findings inform the development of evidence-based ROP screening guidelines.
- Improved screening strategies can lead to earlier detection and treatment of ROP, reducing visual impairment.
- This research contributes to optimizing resource allocation for neonatal eye care programs.
Abstract:
Few data exist from which an optimal strategy for retinopathy of prematurity (ROP) screening can be deduced. This strategy should compromise between the dual purpose of screening, to wit monitoring the incidence of ROP and determining an optimal moment for therapeutic intervention. We recorded the timely incidence and course of ROP in all except four premature infants admitted during a 1-year period. The study results indicated that a single screening moment is not likely to detect more than 70% of all cases. When relying, however, on a single screening the investigation should be performed between the 7th and 9th week. The unpredictable course of ROP, varying between early starting, rapidly progressing forms and very late starting, usually benign forms, probably precludes the possibility of 100% ROP detection. Screening during the 4th to 5th, 8th and 11th week probably gives the best chances for determination of an optimal moment for treatment and approximation of the incidence.
