Insights
The number of laser spots and stage 3 retinopathy of prematurity (ROP) significantly correlate with myopia in preterm infants treated with laser photocoagulation (LPC). These findings highlight key factors influencing refractive outcomes after ROP treatment.
Area of Science:
- Ophthalmology
- Neonatology
- Pediatric Medicine
Background:
- Retinopathy of prematurity (ROP) is a significant cause of visual impairment in preterm infants.
- Laser photocoagulation (LPC) is a common treatment for ROP, but its long-term effects on refractive error are not fully understood.
- Understanding factors influencing refractive outcomes is crucial for optimizing ROP management and predicting visual prognosis.
Purpose of the Study:
- To investigate the relationship between corrected 1-year-old refraction values and risk factors in preterm infants treated with LPC for ROP.
- To identify specific clinical parameters associated with refractive outcomes following ROP treatment.
Main Methods:
- Retrospective evaluation of ophthalmic examination findings in preterm neonates with Type I ROP who received LPC therapy.
- Multivariable linear regression analysis was used to assess the association between spherical equivalent (SE) values and clinical findings.
- Included 157 eyes from 80 neonates with a mean gestational age of 27.1 weeks.
Main Results:
- The mean spherical equivalent (SE) at 1-year corrected age was 0.31 ± 1.89 diopters.
- Univariate analysis showed a significant association between the number of laser spots and stage 3 ROP with SE values.
- Multivariable analysis confirmed that both the number of laser spots (ß = -0.25 ± 0.00 D, p=0.01) and stage 3 ROP (ß = -0.28 ± 0.36 D, p=0.00) were significantly associated with SE.
Conclusions:
- The stage of ROP and the number of laser spots applied during LPC treatment are significantly correlated with the degree of myopia.
- These findings suggest that treatment intensity and ROP severity are important determinants of refractive error development in treated preterm infants.
- Further research can explore strategies to mitigate myopia progression in this vulnerable population.
Purpose:
To investigate the relationship between the development of corrected 1-year-old refraction values and risk factors in preterm infants who underwent laser photocoagulation (LPC) therapy for retinopathy of prematurity (ROP).
Methods:
The ophthalmic examination findings of preterm neonates who had developed Type I ROP and received LPC therapy were evaluated retrospectively. The association between spherical equivalent (SE) values and clinical findings were analyzed by using multivariable linear regression analysis.
Results:
The study included 157 eyes of 80 neonates with a mean birth week of 27.1 ± 2.2 weeks (23 to 32 weeks) and a mean birth weight of 995 ± 273 g (565 to 1760 g). The treatments were administered on an average of 36.8 ± 2.7 (32 to 45 weeks) postmenstrual age. LPC treatment was applied bilaterally to 77 of the 80 neonates included in the study, and unilaterally to 3 of them. The mean ± standard deviation of the SE value was 0.31 ± 1.89 diopters (D) (- 8.00 to 4.63 D) according to the results of the 1-year corrected age refraction examination. In univariate analysis, no significant association between GA, BW, and ROP zone and SE value, while the number of laser spots (ß = - 0.27 ± 0.00 D, p = 0.00) and stage 3 ROP (ß = - 0.29 ± 0.37 D, p = 0.00) were significantly associated with the SE value. In multivariable linear regression analysis, a significant association between number of laser spot, stage 3 ROP and SE value (ß = - 0.25 ± 0.00 D, p = 0.01 for number of laser spot, ß = - 0.28 ± 0.36 D, p = 0.00 for stage 3 ROP).
Conclusion:
In conclusion, this study supports that stage of ROP and the number of laser spots count applied in photocoagulation treatment for ROP is significantly correlated with degree of myopia (p < 0.05).
