Insights
Retinopathy of prematurity (ROP) affected 19.4% of preterm infants in Costa Rica (2010-2014). Most ROP cases required laser treatment, with severe visual impairment rare in this screening program.
Area of Science:
- Ophthalmology
- Neonatology
- Public Health
Background:
- Retinopathy of prematurity (ROP) is a significant cause of visual impairment in preterm infants.
- Effective screening and timely treatment are crucial for preventing severe visual outcomes.
Purpose of the Study:
- To analyze demographic data, risk factors, and treatment outcomes for ROP in Costa Rica.
- To evaluate the current ROP screening and treatment protocols within the national healthcare system.
Main Methods:
- Retrospective review of medical records for preterm infants (≤34 weeks GA or ≤1750g BW) from January 2010 to December 2014.
- Data collected included ROP incidence, risk factors, treatment rates, and outcomes.
- Comparison with international screening criteria and ROP incidence data.
Main Results:
- A total of 3018 preterm infants were included in the study.
- ROP was diagnosed in 19.4% (585/3018) of infants.
- Laser treatment was required for 15.4% (90/585) of ROP cases, with 53% having a birth weight <1000g.
- Severe visual impairment occurred in 0.07% (2/3018) of screened infants.
Conclusions:
- Comprehensive data on ROP care in Costa Rica were established.
- The findings allow for the assessment and comparison of ROP screening criteria and treatment protocols.
- The study highlights the effectiveness of the implemented screening program in minimizing severe visual impairment.
Aim:
To determine the recent demographic data, risk factors and results of retinopathy of prematurity (ROP) screening and treatment in Costa Rica.
Methods:
The medical records of all preterm infants meeting ROP screening criteria (≤34 weeks' gestational age (GA) or birth weight (BW) ≤1750g, and those determined at risk by neonatologists) in the national healthcare system, Costa Rica, January 2010-December 2014, were retrospectively reviewed. The numbers and percentages of infants with ROP, risk factors, percentage of patients treated and treatment outcomes were determined. Comparison is made with screening criteria and literature reports of ROP incidence in other countries.
Results:
The study population included 3018 preterm infants. Overall, 585 patients (585/3018, 19.4%) were found to have ROP. Of these, 15.4% (90 patients) required laser treatment, and 53% of those requiring treatment had BW <1000g. Five babies requiring treatment were ≥32 weeks' GA but with BW ≤1750g. Aggressive posterior disease was found in nine patients, and two infants of those screened (2/3018, 0.07%) suffered severe visual impairment during the 5-year study period.
Conclusion:
We provide comprehensive data of ROP care in Costa Rica allowing assessment and comparison of screening criteria and protocol.
